Did you watch Meteorite Men last week? If not, you can probably catch a repeat. It is a new series, airing 9pm ET/PT Wednesday nights, on the Science Channel about two guys who search for meteorites. Check your local listings for times. (Photo cheekily snapped from their site. Copyright aerolite meteorites.)
I learned about it from Bob Melisso, my producer/filmmaker friend (and occasional collaborator: see here, here and here) who made the pilot and is the supervising producer for the series. From the website: Continue reading ‘Meteorite Men!’
Amy Mainzer has shared and discussed the first released picture from the WISE project that was launched (you’ll recall) not so long ago. It looks marvellous. Press release here.
By the way, I hope you’re following Amy’s blog to learn more about the mission now it is in full swing. She’s giving you a window into the science as it breaks and the excitement of doing the science itself, seeing a project come together Continue reading ‘Eye on the Sky’
My friend, The Universe co-contributor, and colleague Amy Mainzer (JPL) is rubbing gloved hands together in the chilly night air up at Vandenberg. Well, ok, if not this very moment, she probably will be at various points this evening and into the wee hours of the morning. The launch pad for WISE (the mission on which Amy is deputy project scientist) is set, and everything is ready to go! See my earlier post about what Continue reading ‘Imminent Launch’
The skies have cleared here in Los Angeles after a sequence of remarkably rainy days - really torrential downpours that have been very enjoyable. Happily, the clearing has taken place just in time to see the Geminid meteors, which I learned are likely to be quite striking this year*. After midnight or so ought to be good for viewing, and be sure to be looking at the right part of the sky (they originate from the direction of Gemini - see the NASA map on the right). There’s more about it on NASA’s site, and be sure to look at their tips for viewing.
Don’t forget: - don’t assume that being in a large city means you can’t see anything Continue reading ‘Geminids!’
Once again I’m excited about a new piece of machinery. This time it is a space mission again. There have been several remarkable missions launched (many in very recent years), doing all sorts of excellent science, helping us discover all sorts of things about our universe, near and far, young and old. I’ve spoken about (and sometimes followed live) the launches of some of them here on the blog, or spoken about the science results they’ve helped produce. See the graphic on the right for some of them.
Well, very soon (possibly as early as December 9th), there will be the launch of WISE, the Wide-field Infrared Survey Explorer! I learned from my friend, colleague and fellow presenter on History Channel’s The Universe, JPL’s Amy Mainzer, who is a senior scientist and the deputy project scientist on the WISE mission, that they made a series of exciting videos about WISE for you to learn about the science that WISE will do and how it will go about Continue reading ‘Get Wise to WISE’
Well, I’m simply exhausted. I gave my second two-hour lecture today and drained my energy resources quite a bit. This is after an early(ish) start to the morning (7:30am) and with going late to bed last night (1:30am). A good lunch afterward helped restore things to a balance a bit, but I need to rest some more.
I’ve been modifying my lectures during the process of giving them, making adjustments for time and the kind of questions I get. This means that I end up kicking some parts to later lectures, and then trying to spend some of the afternoon writing new material, as well as on the train back to my hotel, and in the evenings.
Well, briefly in the evenings so far. That is because last night was set aside for a tour of some of the tapas you can find in the old part of Madrid. I had the presence of mind to go back to my hotel and get a short nap first, and then met my gracious Continue reading ‘Working and Playing Hard’
I had a lot of time to kill in Philadelphia’s International Airport on Sunday (I was changing planes), and I must say that is not a bad airport in which to be in such a situation. I like the city a lot, and so am not surprised that its main airport is to my liking. First of all, who can not like an airport that supplies you with… (you’re expecting free wireless, and they had that, sure, but no, I mean)… with… Rocking Chairs!!!
I saw some excellent art as well. And lots of displays of various types. I’ll share a couple more in a post or two, but look at some of the pieces I snapped pictures of for you. They are done with packing tape! Yes, packing tape. That brown thin stuff you know well… It was part of a series of scenes from noir films, rendered in this way. Very effective indeed, I felt. The series name is “Tape Noir”.
Another meteor shower is almost upon us. Next week it is the turn of the Leonids. Now, as the name implies, these have their apparent origin in the constellation Leo. So how visible it will be for you, if you live in an urban area, might depend upon Leo’s position in the sky relative to your local bright city lights at the time of viewing. But it is worth trying. Look for a public park, rooftop, or other open area of sky. Parks can be better for pulling you away from some of the immediate lights, and then sit still and look at one patch of sky steadily for a while (generally in the right direction!) To get Continue reading ‘The Leonids are almost here!’
Aha! So you were thinking the mission last month was a bit of a failure, right? Because there was no big splash (literally) of a plume for the press to gush about? I’m talking about the October LCROSS mission on October 9th that smashed an impactor onto the moon’s surface (at the Cabeus crater) to create a cloud of dust for analysis. I remember people thinking, encouraged by various reports, that the event was rather a damp squib, since it did not produce a Hollywood-style flash and plume. See an NPR report on the mission here from back then.
Well, science is known for being able to carry on steadily even if there are no overt special effects and a catchy soundtrack. Today, NASA announced that their analysis of the data produced from measuring the dust cloud’s properties has shown very definite signs of water (confirming and strengthening the results accumulated by other missions (India’s Chandrayaan-1 and NASA’s Deep Impact and Cassini probes) that I Continue reading ‘Wet Moon’
You may recall my mentioning a desert trip to shoot something for TV, some time back. One done at precisely the wrong time of year. And to Death Valley, one of the hottest places on earth, to boot. Well, I meant to mention that the episode of the History Channel’s The Universe that the shoot was for aired a week or two ago and it was really excellent. It was entitled “Liquid Universe” and it was a rather beautiful and thoroughly pleasant episode exploring the role of liquids in our universe, a matter not often raised in questions of astronomy except when it comes to matters of water from time to time. This was not about water per se, but rather the whole matter of material that flows and the role it plays in diverse areas of the solar system and perhaps the universe at large. I was using sand to demonstrate how sometimes there are surprising places where you can find fluid/liquid behaviour, and mentioned some of the new phases of matter found in the context, for example, of quarks and gluons at RHIC. (I’ve spoken about that here a number of times in the context of some of my research. See the archives.)
This is a photo I borrowed from Dara Norman’s blog post over on NSBP’s Vector. It is about the star party held over at hhe White House in October of this year. It looks like it was a lot of fun! Er, you may recognize one or two of those people at the telescope…
Here’s a fun thing to get involved with. You can ask John Mather (2006 Physics Nobel Prize) a question on YouTube! Go and submit yours!
What might you ask him? Something about physics, or something else? Religion, art, politics? His favourite colour? If you consider asking a question, and whether you go ahead and ask it or not, feel free to mention in the comments what you might ask.
The Orionids peak today. Well, actually, they peaked a few hours ago, but I imagine there’ll still be some excellent viewing of this meteor shower the next night or two. If you’re up late or very early and out for a walk (in the pre-dawn hours), look up, stay steady for a while, and see what you can see. You’re looking just above Orion’s shoulder (you know Orion since I am sure you are often struck by those three equidistant stars in his belt…see the diagram on right from NASA’s site) for the apparent source of these fragments of Halley’s comet’s tail that we happen to be passing through. It is these chunks of comet-tail that enter our atmosphere and produce what we see as meteors.
Friday evening was very enjoyable indeed, with some arts and literature near the start, and live scientific research toward the end. It began with a nice trundle across town on the 920 bus, when it eventually arrived (why are there still so many long gaps in the 720 and 920 schedules at crucial times of the day?) heading over to Westwood to the UCLA campus. I listened to music, read Jonathan Gold’s column in the LA Weekly, and listened to conversations around me. I got to Westwood and Wilshire after half an hour or so and walked up to campus and to Royce Hall, getting coffee on the way and even stopping in to an AT&T store to check on something. The campus was surprisingly quiet at 7:30 or so and I made my way over to Royce Hall, sending a text to a friend about later.
Besides the environmental reason I like to try to take public transport, it is also nice to plan it out and then be 15 minutes early and nice and relaxed before an event, and not be arriving all stressed due to traffic and then worried about parking and so forth. The show started late (as everything does in LA because there is a tacit assumption that everyone will be late due to traffic and parking and so people mostly were late because, of course, they know this assumption is in place. (At the 8:00pm actual official start time only about 20% of the audience that would arrive in the next 15 minutes were actually seated.)
The event, you’ll recall, was all about Margaret Atwood’s new book Year of the Flood. The author and the actors and musicians came onto the nicely decorated set and started with one of the songs specially written for the event. There is a limited set of engagements in 16 or 20 (I’ve forgotten) cities performing this reading and this is one of them. Margaret Atwood was the narrator and there were three actors reading the parts of three characters from the book. A central cult/religion that appears in the book (and the previous book with Continue reading ‘Friday Night Observations’
I’m sitting on the sofa watching what has so far been a really excellent episode of The Universe on the History Channel. It is entitled “Cosmic Clusters” and it has been a lovely journey (15 minutes show time gone by so far) on an imaginary spaceship ride through the galaxy looking at formations of star clusters, and discussing the process of star formation in those clusters, their birth and the conditions involved, how those conditions change as things progress, the different kinds of stars that can result, the curious case of globular clusters (M13 is pictured below, by Yuugi Kitahara) and so forth. I think it is going to go on to discuss clusters of galaxies, and clusters of those…
I’ve learned quite a bit so far from watching it, actually. It is a really lovely discussion with excellent contributions from my friend and colleague Amy Mainzer, Alex Continue reading ‘Clusters’
Well, I’ve been somewhat neglectful of lots of space and astronomy type noticing (here on the blog) in the last couple of months or more, but it is not unusual for me to re-balance my foci a bit as my interests and available time permits. However, I’ve been meaning to point to the quite astonishing results that are being discussed in recent days… The confirmation of what appears to be a remarkable amount of water on the moon. It is an indirect set of measurements, using spectroscopy, (using results from three separate spacecraft) and is quite an interesting story. Happily, Phil over at Bad Astronomy has just put up a rather splendid summary of the story and I’m simply going to recommend that you pop over there and have a read. (There’s also a Space.com story by Andrea Thompson that is nice too.) Very interesting in the whole thing is the discussion of how the water got there, and why it is rather more mobile than you might expect (clue: the sun might be involved).
I’ve been wondering why over the last day or two I’ve been getting email about various apocalyptic scenarios. I’ve now figured out why, I think. On Tuesday, several scientists, myself included, played with the idea of how to destroy the earth! Well, it was on the History Channel in an episode of the show the Universe, (it was recorded back in June and July) entitled “Ten Ways to Destroy the Earth”. Of course, these are not scenarios we envision happening any time soon, but rather an excuse to talk about various kinds of science (from spontaneous symmetry breaking and the early universe, through planetary science, solar physics, and of course black holes and more). We list various favourite ways that were chosen to be discussed, and each physicist (although they called me an astrophysicist) picks a favourite. Fun stuff.
Well, here it is. After lots of interruptions over the last 24 hours, I give you the trailer for Laser, the next of my films. I think it is a bit more playfully enigmatic than the trailer for the first film. (I’ve only just (half an hour ago) finished recording the music for it, and so it really is being rushed to you straight from the cutting room, as it were.)
See earlier posts for my thoughts about the project, and see the trailer for the first film here, and the actual first film, Shine a Light, here. Sorry it is so late… the semester started and I got swamped. See my chatter about that here.
Well, ok… Boom is not quite accurate, but the idea is that there will be ten kinds of blasts/explosions/major_energetic_events discussed tonight on the History Channel’s The Universe:
The Universe is full of explosions that both create and destroy. The Chicxulub impact on the Yucatan peninsula, which may have wiped out the dinosaurs 65 million years ago, was two million times more powerful than the largest nuclear bomb ever detonated on Earth. But guess what? That’s only good enough for the very bottom of the Biggest Blasts top ten list. This episode works its way up through supernova explosions and gamma ray bursts all the way to the blast that started it all–the Big Bang.
Sounds good doesn’t it? There’s a lot of good people contributing again, so I know it’ll have some good material and explanations.
In addition, I’m reasonably confident I play a role in this one…This one was a blast (sorry) to film. You saw some posts earlier reporting on some of the filming. Assuming they used the material I did with them, you’ll get to see why I was at the Continue reading ‘Ten Things That Go Boom!’
Tonight’s 9:00pm episode of the History Channel’s The Universe ought to be interesting. It is all about objects that fall to earth from space. It’s a good opportunity to learn things about the universe (both near and far) from the perspective of things we glimpse arriving here on earth. You’ll get to learn about the earth as well, and how it (and life on it) has been affected by these things. There’ll be asteroids and planetary science of course, and maybe other things. I know from hearing some chatter of the program makers that there’ll be lots of demos using impacts and collisions and so forth. I know some good people were involved in making it, such as the writer/director Laura Verklan, and my friend and fellow regular on the show, JPL’s Amy Mainzer (who has an excellent blog here). Continue reading ‘It Fell From Space…’
Continuing my series of posts on the approach of the fires to Mount Wilson and the threat to the Observatory (see previous for information and discussion - this morning I am happy to hear that the radio news is now mentioning the Observatory and not just the tv and radio antennae up there)… Last night at about midnight I decided to look out to see whether I could see anything going on, and was greeted with a sight from the pages of Tolkien describing Orodruin (Mount Doom):
The fires are racing up the sides of Mount Wilson as I write (19:38). They expect the burn to get to the top sometime in the next few hours, and yes, I imagine it’ll affect the Mount Wilson Observatory in some way.
[Update (20:59): You can get regular updates from the director at this page*. Seems that fire crews will remain on site for when/if the fires sweep through the grounds. ]
All of the working scientific equipment, including the solar telescopes and of course the historic telescopes (the 60 inch is pictured to the right) with which astounding discoveries were made about our universe (such as the fact that it is expanding, and the fact that the universe is vastly more than just our Milky Way Galaxy) are presumably in some danger, as well as support buildings of various kinds. I’ve no idea how much since I do not know what fire-proofing measures are in place up there, although I am sure there are several - such as keeping brush away from the buildings themselves. Here’s a camera up there on one of the solar telescopes where you can see regularly updated pictures that it snaps. I grabbed this one just now (click for larger view):
There’s a remarkable amount of smoke in the skies here in Los Angeles. Strangely there is little or no wind to accompany this super-hot day, and so the smoke is largely staying over the region where the fires are - the San Gabriel mountains, North of La Canada, Altadena, etc.
There was a bit of movement of the smoke overnight, and early this morning (while the sun shone dull and red like a sunset instead of a sunrise) there was some ash fall over where I live (I was working outside on some writing while it was still cool), a good number of miles away from the fires, in the city of Los Angeles itself, but this seems to have gone away. So there are clear skies in all directions, and then ominous-looking mushroom clouds in one direction. It is odd. This stillness is the reason the firefighters are having a lot of difficulty fighting the fires, actually - the smoke is affecting visibility for the various ground and airborne crews. There’s a lot of concern about what the fires will do next, (including a threat to the Mt. Wilson Observatory) and so let’s all keep out fingers crossed for luck. [Update: 6:30pm - I've heard that they have no choice but the let the fires take Mount Wilson. I hope that the Observatory survives ok. If you're not familiar with the significance of the Mount Wilson Observatory, read here and here.]
Here’s a recent (about 5:00pm today) shot of the mushroom clouds of smoke. You can Continue reading ‘Smoke’
I learned* a short while ago that the fourth season of The Universe on the History Channel starts tonight! As you may have read from a number of posts of mine over the last couple of months (see e.g. here, here and here), there’s been a lot of filming for this new cluster of episodes. I actually thought it was all going to start airing in the Fall, so this is a surprise to me.
There are some fun topics coming up in this season. There’ll be plenty of interesting things to learn, with contributions from a variety of interesting scientists telling you Continue reading ‘The Universe: Season 4′
I’m 24 hours too late to warn you of the peak, which was this morning, but I imagine it will still be very good over the next few nights. This is the Perseid meteor shower. Apparently it is very good this year. So wander out when it is dark enough and see what you can see. Look toward Perseus, of course. More information here, from the Meteor blog, and the ever-excellent Stardate site gives you some directions (or look here).
It is Friday, so time for a film release. So, get your popcorn, your ice-cold drink, and find your comfy chair! It has been a long time coming (see related posts listed below), but finally the first of the series of films I’ve been talking about is ready for you!
But before I run the projector, let me say a few words. As I said before, this short film is (I hope) fun, engaging, and informative. I hope lots of people take the time to watch it at least a couple of times. A basic scientific knowledge of the world is for everyone. Science is part of our culture and should be more widely circulated. Films such as this is one of the ways the National Science Foundation, who provided the support to make it, is helping to bring science to everyone. For this (and the other ones in the series) to be a success, your help is needed. It needs to be seen. Tell your family and friends, colleagues and students, local teachers, etc., about it. Forward it on to people you know. Blog it, tweet it, facebook share it, etc. Crucially, remember that it is designed to be not just for people who already know they have an interest in science, but others too, so make no assumptions about who might like it… just please send it. Thanks.
Ok, let’s dim the lights! Run the Projector! (Tip: It is a high video quality, so pause it and let it buffer Continue reading ‘Shine a Light’
Dennis Overbye wrote a nice summary article in the New York Times about the current status of the delays to the Large Hadron Colllider’s (LHC’s) re-opening. (Photo left by Valerio Mezzanotti for NYT) The issue is very frustrating, overall, even though one knows that delays like this can happen (and ought to be expected to happen) if you’ve built the largest and most complicated machine ever. I (and many colleagues) have in some sense waited for the LHC almost my entire professional career, and last Summer/Fall it seemed so close to finally starting to give us physics, only to have the failure happen, and set it all back. That’s life, of course. These things happen. I’ve a great deal of faith in the Continue reading ‘LHC Update’
One of the offerings for my 17 guests during my solstice celebratory cooking session yesterday. (Click for larger view.) For background, see yesterday’s post.
I produced five or six core dishes for the menu, overall. Boy, that was fun! (There were also some excellent dishes brought by guests, and I had various other things Continue reading ‘Solstice Salad’
The Sun stood still earlier today! Don’t panic - It is Summer Solstice. I’m talking about an apparent motion of the sun, or, more accurately the migration of its path across the sky. Take a moment to think celestially for a bit and ponder the earth as it goes around the sun on its annual path. There’s a tilt to the earth’s own rotation axis, remember? (About 23 degrees). That tilt results in our seasons, and the path of the sun through the daily sky. Visualize this for a moment and it’ll make sense, if you let it. Today the sun’s path has got as northernmost as it will get, and it is now turning around, being more Southern each day until Winter Solstice. To turn around and change direction, you first have to stop. No way around it. So, the sun stood still today.
So, I decided to celebrate all this lovely geometry on the spur(ish) of the moment. Will you? I’m going to cook up several tasty dishes and have some friends around to Continue reading ‘Summer Solstice!’
I just learned from Phil’s blog that the Galileoscopes I mentioned to you some months back (remember? International Year of Astronomy? Not just Darwin year?) are ready for shipping. There were issues with production at first, but now they are ready. The key issue right now seems to be that they are in danger of having to stop production of these lovely things if they don’t get lots of orders by May 31st. Ack!
So please please consider sending in a order for one or a few. Imagine what a delightfully unusual gift it would make for someone. Either someone you know, or someone you don’t know like a neighbour, your local school, church (yes!) or community center, or… even that special someone who you’d like to get to know - what an icebreaker, eh? Here’s a picture from the site of what a happy owner’ll have after assembling it:
The space shuttle mission launching today (around 2:00pm ET) has a very special task. It is going to take some astronauts up to do some crucial repairs (see story here) on the Hubble Space Telescope. It is the last such mission (Hubble will be retired into the Pacific eventually) and has been long awaited. Please keep your fingers crossed for a successful mission to keep such an important scientific instrument working for another five (or so) years to teach us more about the universe. (Go to the Hubble site here.)
NPR had a rather good piece about the special tools that were designed to allow these repairs to be carried out. The point is that the astronauts are not just swapping out parts or modules that were designed to be swapped out (like you do a light bulb, a shower head, or a shaving foil), but they have to go in and take out things deeper Continue reading ‘The Right Tools for the Job’
I had a lot of fun at this year’s Jet Propulsion Laboratory (JPL)open house. I’m happy to report that there were, once again, lots of people wandering around looking at the displays and demonstrations, asking questions, hanging out, and so forth, and an impressive turnout of JPL staff answering questions and being very enthusiastic about the science (something which is easy to do because it’s such an excellent topic!). I’ve made a video for you that is coming up at the end of this post. (Click on stills for larger views.)
There was the usual huge emphasis on planetary exploration with rovers and robots and so forth - this seems to capture the imagination of everyone, so why not? - but I was more than a little surprised to find virtually no showing for the Planck mission. There was one poster somewhere, but no booth, no model, no description of the truly amazing science that it will do in unlocking more about the origins of the entireContinue reading ‘Yesterday at JPL’
It is that time of year again. The Jet Propulsion Laboratory is having an open house this weekend, 2-3 May 2009! This is excellent news, as I’ve been very impressed with the open house in past years, and I am pleased that it has continued. There’s a real dedication to doing it well, with lots of volunteers giving of their time to make it a really high quality event. I recommend it. Their event page is here. You might find my description of one of the visits I did useful as a guide to what to expect. It is here.
I promised a report on last week’s College Commons trip to the Page Museum at the Tar Pits, here in Los Angeles. It was an excellent trip. The usual thing I do for blogging these things is, some time later, as time allows, I sit down and do a sort of brain-dump. I tried to do something different this time, and walk on the tour with my Palm Tungsten (yes, really really old technology, I know) and simply write a sort of narrative into it as I went along. Then I combined the uploaded file with the images I took as I went along, and supplemented with some extra sentences here and there. The overall effect should be a sketchier description of the event than I usually do, which may or may not be an improvement given that everybody seems to skim everything these days anyway. (Click on the photos for larger views.) So, here goes:
And so it begins. And it begins well - after a name tag is given out, upon check in for the bus, we are given a little brown paper bag of snacks. Hurrah!
3:39 and we’re off! (We run by the excavations for the Expo line and since it is an elevated bus, I get a nice view of what’s going on for quite a way. Wish I’d had the camera out to make a video for you.)
My colleague David Bottjer, a paleontologist, gives a little run down of the history of the region (both social and paleontological) as we go north on La Brea (appropriately - they are the La Brea Tar Pits… Or given that La Brea means The Tar, they are The Tar Tar Pits…)
4:05 We’re here! Somehow, the little bag of goodies is all empty already. Except for Continue reading ‘Pit Visit’
This weekend, you might like to participate in the 100 Hours of Astronomy events going on all over the world. Recall that it is the International Year of Astronomy, and that there are lots of things going to celebrate the 400 years of the Astronomy era launched by Galileo’s use of the telescope for his landmark Astronomical observations. There are all kinds of exciting events, from local astronomers setting up telescopes in your neighbourhood for all to use, to things involving some of the great professional telescopes around the world live webcasting and even… twittering. From the main page of the organizers:
Over on Bad Astronomy, Phil has a nice article entitled “Ten Things You Don’t Know About Pluto”. It is nicely illustrated, and indeed, some of those things he mentions might be new to you. Go and have a look and see.
Did you watch Meteorite Men last week? If not, you can probably catch a repeat. It is a new series, airing 9pm ET/PT Wednesday nights, on the Science Channel about two guys who search for meteorites.
