Altair: The Hottest Magnetically Active Star in X-rays

OK, so now you have a new trivia pursuit question you can use with the astronomers among you. Altair is the brightest star in the constellation Aquila the eagle. It’s close to 17 light years distant, and is the 12th brightest star in our night skies. Utilizing the XMM-Newton x-ray telescope in orbit about Earth, astronomers have concluded that Altair is about as magnetically active as is possible.

NASA’s Constellation Program

Hey Fellow Astrocasters!

I hope you have high speed Internet because you will want to see all of the INCREDIBLE multimedia videos at NASA’s Constellation website.

We used some of the stills and clips in Episode 12, but you have to experience all of the video clips – with the volume up – to really get the real thrill of seeing NASA’s new rockets and moonships. It isn’t quite “2001″ but it isn’t bad for the little screen.

Happy Moondreaming!

Greg
