The Ultimate Television

Huffington Post - Seth Shostak - Fri, 2013-02-01 17:52
Television technology is not in Kansas anymore. Image displays are about to go where no displays have gone before. Nonetheless, I figure they'll hit the equivalent of a brick wall within a decade or two. There will be an end point to how good TV pictures can get.

Space art competition for kids

"Bad Astronomy" - Wed, 2012-10-24 15:30

More art and science are colliding! The Lunar and Planetary Institute is hosting the Humans in Space Youth Art Competition. Kids from anywhere in the world ages 10 – 18 are encouraged to express their feelings about human spaceflight using "…visual, literary, musical and video artwork".

I’m a big supporter of scientific art, and I think this is a great idea. If you’re that age, or know someone who is, let them know! The deadline for submitting the work is midnight U.S. Central Standard Time, November 15, 2012. The website has the details.

Go! Be artistic!

Pew! Pew! Take *that*, Mars!

"Bad Astronomy" - Wed, 2012-10-24 13:00

Hey, remember that one ton nuclear rover we sent to Mars? Yeah, that. On October 20, it aimed its megaWatt laser at the sand on Mars and blasted it 30 times in rapid succession, carving out a hole about 3 mm across. NASA kindly has provided a before-and-after animation of the damage inflicted on the Red Planet:

Cool, eh? [Click to coherentlightenate.]

Curiosity’s laser is designed not as a weapon against a hapless Marvin, but instead to do actual science. It very rapidly heats the rock (or sand or whatever) to the point where it vaporizes. Material heated like that glows, and in fact glows at very specific colors. By identifying those colors, scientists can determine precisely what the material is composed of. I gave the details in an earlier post when Curiosity zapped its first rock. You should read it, because spectroscopy is cool, and I spent many years doing it.

This sand was chosen to get lasered because it’s made of fine grains that are blown by the wind. Some Martian sand is bigger, some smaller, but it’s all pretty much formed from eroded rocks. But different grains may have different compositions, and ...

NuSTAR catches a black hole’s hot belch

"Bad Astronomy" - Tue, 2012-10-23 19:33

Our Milky Way galaxy is a sprawling collection of gas, dust, and hundreds of billions of stars, arrayed in a more-or-less flat disk. In the very center of the galaxy – just as in countless other large galaxies like ours – lies a hidden monster: a black hole. And not just any black hole, but one with four million times the Sun’s mass.

It’s called a supermassive black hole for a reason.

Usually, it’s not doing a whole lot except sitting there being black and holey. But sometimes it gets a little snack, and when it does it can let out a cosmic-sized belch. A very, very, very hot belch. Like it did in July 2012:

[Click to schwarzschildenate.]

These images were taken with NASA’s newest X-ray satellite, NuSTAR (more on that in a sec). NuSTAR can detect high-energy X-rays coming from space, and happened to be pointed toward the black hole when it erupted. On the left is an overview of the region near the center of our galaxy. The whitish area is the stuff immediately surrounding the black hole (the pink glow is most likely from a ...
