Why is everyone excited about this picture?
Actually, there’s a dot on the bottom left quadrant. What is it? What did the excellent photographer Thierry Legault manage to image?
Well, it’s wonderful: […] Click to continue reading this post
Tomorrow is the Big Day. For what? The launch of Planck and Herschel – Major new windows on our universe. Keep your fingers crossed for luck!
They’re on the launch pad right now. See here.
So, what are the missions and objectives of these fine spacecraft, I hear you ask.
Well, from the Planck site: […] Click to continue reading this post
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 […] Click to continue reading this post
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 entire […] Click to continue reading this post
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 … Click to continue reading this post

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 […] Click to continue reading this post
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. (And don’t forget it is International Year of Astronomy, … Click to continue reading this post
Gosh, time flies!
I almost did not get to announce this before it was upon us. Tomorrow and the day after combine into a notable event in the College Commons series here at USC. Some of us have been working on this for quite a while. On Tuesday we have Stephen Hawking giving a big public lecture entitled “Out of a Black Hole”. Here’s the announcement. Note that general tickets for seats in Bovard Auditorium all went within hours of us releasing the tickets several weeks ago, but there is room in the two spill rooms that we have set up where there will be screens relaying the talk. Make a bit of an event of it and go with friends! [Update: I forgot to mention that we had a competition in local high schools and also at USC where the prize was to ask Stephen Hawking a question. People submitted questions over the last few weeks and we selected some of the best. There will be three undergraduates and three high school students coming up from the audience (we’ve a lot of high school students visiting us for the talk) to ask him a question each at the end. Should be fun.]
The day after, there will be a related event. Some of us from the physics department […] Click to continue reading this post
This post would be better suited to three weeks from now, but the subject item is so very good, so here goes…
Astronomers Declare February No Longer a Month
Emboldened by their success in declaring Pluto not a planet, the International Astronomical Union determined this week by a close vote that February is too short to be considered a true month. It has, however, been granted the newly created status of “dwarf month.” It shares this dubious distinction with several other calendar time spans, including Labor Day Weekend, Christmas Vacation, and the Time Between When You Were Supposed to Get Your Oil Changed and When You Actually Did.
“It only seems fair,” said IAU President Ron Eckers. “February reaches a peak […] Click to continue reading this post
I learned* that the Kepler craft (NASA artist sketch on right – this is the device that will look for “other earths” – see below) is all go to try for launch later today! Extract from an announcement that went around:
On 6 March (EST, 7 March in UTC) there are two opportunities for a launch into the Earth trailing orbit. The first window is at 6 March, 10:49:57 p.m. EST (UTC: 7 March, 03:49:57) and the second window is at 11:17:44 p.m. EST (UTC: 7 March, 04:17:44). If Kepler is not launched tonight there is a another possibility at approximately the same time tomorrow night.
Countdown will begin 3 hours before launch and Kepler separation into Earth trailing solar orbit will take place 3709 sec into flight. First contact after separation is expected 4640 sec into flight.
For more information, and to follow the launch live, here are some links: NASA TV, Launch Blog, Spaceflight.
I noticed that Amy Mainzer is over at the Kennedy Space Center to see the launch. She begins to talk about it here on her (excellent) blog. You might want to check back there in case she does a nice report on it. Check out Phil’s Bad Astronomy blog for more on this too. He says he’ll be tweeting and all. (Yes. Tweeting. There, I have used that word in its recent new context/meaning in a sentence for the first time. I feel a bit silly.)
What is this all about? It is very exciting. Here are some sources of information for […] Click to continue reading this post
The next Categorically Not! is on Sunday February 1st. The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events.
The theme this month is Dark Matters. Here’s the description from K C Cole:
This year is not all about Darwin. There’s even more fun to be had. It is the International Year of Astronomy. It is 400 years since Galileo Galilei looked at the night sky using a telescope, and this is regarded by some as the birth of modern astronomy. There’ll be lots of celebratory events and discussions taking place under this banner, and of course it is a wonderful opportunity to highlight and kindle interest in Astronomy, so keep your eye out for lots of such events. The theme is “The Universe: Yours To Discover”, which I think is rather good, don’t you? See the official website of IYA2009 for more information. Here’s a BBC World service piece about it, in the form of an interview with Astronomer Royal, Sir Martin Rees. (That same page has an audio visit to the Vatican’s Observatory, Castel Gandolfo (a facility previously mentioned on the blog here), which might be of interest.)
