I’m repeating myself, I’ve noticed, but it’s ok. Turns out that after I decided today that it was time to post a photo of this lovely flower (click for larger view), I noticed that I’d done exactly the same thing last year, on the same day. It’s the first of the buddleia (budlea) flowers to bloom in the garden, and it’s always a welcome sight. It takes a […] Click to continue reading this post
One of the Phoenix images that has most captivated has been the one that shows the rest of the background of that startling image of the parachute part of the landing phase that was taken by the Reconnaissance orbiter’s HiRiSE camera. I showed it a few days ago here, and it is amazing, for all the reasons I said back then and more. I’m still buzzed by the idea that we have cameras from another craft photographing the landing of a new craft. Well, a while later, the mission released the photo showing the larger backdrop to that image. There’s the (giant 10 km) Heimdall crater in the background! (See the little inset bottom left showing where the previous image focussed; credit: NASA/JPL).
Rather dramatic, wouldn’t you agree? It’s not really as close to the crater as it […] Click to continue reading this post
Brian Greene, theoretical physicist and one of the founders of the World Science Festival in New York (May 28th – June 1st), talked to Stephen Colbert about the excitement of science, and how the festival will give people a chance to see lots of fun exhibits and chat with scientists to find out about the wonderful “adventure story” (nicely put) that is science. He manages to do this pretty well, between giggles generated by sharp fun-poking from Colbert.
There’s the festival, large-breasted alien robots (their words), some fun quips about […]
A reader asked for more string. You can see my reply here. Not being one to deny the punters entirely, 
I’ll pass on some clips from a 70s British TV comedy show, about string. It was a popular show called “The Goodies”. Some of you might remember them. Well, they did an entire episode with the title “It might as well be string”, and although the clips (below) are out of context and even with not knowing the characters and so forth (I don’t) there are some amusing bits here and there, if you turn it around to poke harmless fun at those of us who work on string theory decades later – It’s all about a PR/Advertising campaign for string!
There’s the string song, the “documentary” about string (best to gloss over the oh-so-funny “smelly Arab” remarks and accompanying laughter), the excellent samples from the […] Click to continue reading this post
Marvellous. It is good to get the chance to use the word in its most basic sense, and fully mean it. You know how there’s a lot of reliance on artist’s impressions to depict aspects of space missions (such as landing) that we can’t get photos of because, well, there’s nothing else there to take the photo (unlike the movies and TV)? Well look at this:
It may not look like much to some, but I’m really impressed with this. It is a first. It is the Phoenix lander during the act of landing during the “Seven Minutes of Terror” yesterday! NASA’s Mars Reconnaissance Orbiter was in the right position to take a […] Click to continue reading this post
The first images are showing that everything’s ok. There are several here. From the Phoenix press release site:
16:56 or so: Yep. That was a tense seven minutes. But it is over and they are getting signals. I watched the live feed from the JPL control room. Wow. Who knew this could be so exciting from so far away?! Anybody else watch it?

P.S. Yes, with my choice of title, I’m clearly practicing for the commentary on the Olympic gymnastics… Click to continue reading this post
Remember the launch of the Phoenix spacecraft last summer? I mentioned it in earlier posts (including talking about the mural for it – see here and here) and Phil did a lovely post on the launch here. Have a look at the mission website. Here is a space.com article that gives an update on the mission so far.
Well, today’s the day it approaches and (it is hoped) lands on Mars!! So, the landing. The landing, the landing the landing. It’s all about the landing. The craft has to slow down from 12500 miles per hour to make a soft landing on the surface. In a matter of […] Click to continue reading this post
Have you seen them? March Fourth? They’re quite excellent, rather hard to describe. Clickable photos below open up the somewhat abstract teaser above. They played for an hour at […] Click to continue reading this post
Wetly cloaked mountains, a green hill, a shimmering field of dry grass. Point Mugu State park, early May.

Ok… A dying star. Here’s the before and after shot (images from the NASA Swift team):
An the amazing thing is that they were able to watch and record the events in real time! The galaxy hosting the explosion was already under study because of an earlier supernova. This is wonderful, of course, and a big deal is made in various news articles about how great it is that this is the first time that a supernovae event was caught in real time from an earlier hint from an X-ray emission signature… Except that it seems that it isn’t!!! I do find it a tad annoying/puzzling that in a few seconds I was able to find pretty much the same sort of news announcement from two years ago. Does the press think that the members of general public are stupid, or have no memory? (I don’t yet have time to re-read both articles carefully, so I imagine this is maybe much better (it is rather closer), and there were more telescopes recording, and maybe from earlier, in a wider spectrum, and so forth, but not to mention the earlier event at all, as though a big news story was not made of it back then, is strange. (Perhaps the finding was discredited?) I did a blog post mentioning it entitled “When Stars Go Bang”, and you can link from there to a BBC news article for example of the coverage.)
Anyway, back to the excitement. We must not take away from the joy of discovery: From […] Click to continue reading this post
Oh boy. Not what I really want to read just before going to bed. I’m likely to have dreams of falling into giant cracks* that open up under you no matter where you run. Did you have those when you were a child? I did. That one, and a slightly different version that involved a volcano, where….
Oh, wait. Back to the point. A report has come out with carefully researched projections from geophysicists and […] Click to continue reading this post
I was at an unusual and splendid event on Saturday. My friend and colleague, the writer Aimee Bender, organized a group of 25 of us to go to the top of Mount Wilson and spend the evening, mostly sitting in the dark, right up to well after midnight! What were we doing? Astronomy. We had the Mount Wilson Observatory’s 60 inch telescope entirely at our disposal!! This is not any old 60 inch telescope – it is one of the historic telescopes that’s up there, used since the early part of the 20th Century to discover things about our galaxy and beyond. (See also a post I did about the 100 inch, and the hike you can do up the mountain to see the site. [Update: Note – For this trip, we drove up, carpooling!])
Aimee had reserved the space well in advance, and we had a guide and a telescope operator (the excellent Shelley Bonus and Arbi Karapetian, respectively), and we brought food, which was spread out on a large table alongside vats of coffee and hot water supplied by the observatory.
This is an excellent way to spend an evening. Shelley is informative and enthusiastic, and does a great job of selecting various objects to be viewed (she also takes requests!) and giving lots of information and anecdotes about them, and much else besides. Arbi was also a gold mine of information.
The party was of 24 non-scientists (there were a lot of writers of various types, for example – poets, screenwriters, novellists, experts in poetry and literature and language…) and one physicist. As the latter, I tried to remain undercover, so as not to […] Click to continue reading this post
I really hope the scientists said that when they found this. Really. It’s a mountain, underwater, colonized by millions of starfish. Amazing.
