The highest angular resolution X-ray observatory ever (and likely to hold this title for at least 20 years, maybe more) and first of the current, new generation of X-ray telescopes, the Chandra X-ray Observatory was launched into space onboard the space shuttle Columbia about 10 years ago. For more information on the wonderful science this satellite has helped accomplish, read this article. Chandra really is an amazing facility, and hopefully will last (at least) another 10 years!

Slowly working through to backlog of radio shows I need to put online, now available here is the July 13th episode. This program begins my current discussion of recent scientific results concerning the Solar System and, since it lies at its center, I appropriately start with the Sun. And because it is so close to the Sun, I cover Mercury as well. As always, please email me or leave below any questions, comments, or concerns you might have. Thank you for listening!

Galaxy Zoo, which I personally feel is one of the best ongoing Astronomy programs out there, is looking for people to help identify supernovae - bright flashes of light believed to be produced by explosion of white dwarfs or massive stars - in the Sloan Digital Sky Survey. Go here for more details, and good luck!

Moons can eclipse each other as the orbit their respective planets, as proven in this pretty amazing video from Christopher Go, an amateur astronomer in the Phillipines. Video courtesy of spaceweather.com. Enjoy!
Before reading this New York Times article, I hadn't really thought it was an issue - but after reading it I can see why NASA employs someone to think about these things. Definitely worth a read, I feel. Hope you agree.

Now available here is the June 8th episode of this radio show, not devoted to the wonderful contributions of the scientists whose names are in the title of this post, but the recently launched European astronomy satellites which bear their name. Both Herschel and Planck promise to do some very impressive science, which I hope I did justice too in this show. As always, please email me or leave below any questions, comments, or concerns you might have. Thank you for listening!

Well, actually, right at Dawn. According to spaceweather.com,
at dawn Monday, Aug. 17th, Venus and the crescent Moon will be near each other in the eastern sky. For much of North America, the International Space Station (ISS) will also appear. Check spaceweather.com (naturally) for a sky map and ISS flyby predictions. Enjoy!

Peaking right about now is the the Perseid Meteor shower, when the Earth runs into debris left behind by Comet Swift-Tuttle as it orbits around the Sun - causing these rocks to enter the Earth's atmosphere where they burn up as little meteorites should, producing lovely little trails of fire. In today's New York Times there is an interesting article by Prof. Christopher Cokinos of Utah State University on the history of this meteor show. Go here to read it, I personally enjoyed it quite a bit. Enjoy!
Is that what you call it? Anyway, NASA astronaut Col. Tim Kopra is the first International Space Station crew member to "tweet" about living and working in orbit, in partciulat the International Space Station. To follow Kopra on Twitter, click here. He will also be periodically answering questions submitted here. Enjoy!

The Perseid meteor shower, one of the most active of the year, will peak between sunset on Tuesday, August 11th, and sun rise on Wednesday, August 12th. This is the result of the Earth passing through the tail of dust and ice left behind by Comet Swift-Tuttle as it passes around the Sun. This material isn't stationary, but actually in orbit around the Sun, which is why each year the Earth hits some material. This year the Earth is expected to pass through a denser-than-usual filament of dust, so it should be even more active than normal - with a meteor rates possibly as high as 200 per hour. For more information on this event, read this NASA Science article and visit spaceweather.com. Lots of Astronomy clubs in the NY area are holding observing events, look at the calendar to the right to see if there are any convenient for you. Enjoy!
Also, if you take any pictures, I'd love to link to them from this site. Just leave the URLs in the comments section below.
Here is the May 6th episode of this radio show where I discuss the latest telescope news: from recycling radio telescopes to launching new satellites. Thank you very much for listening, and hope you enjoy.

NASA has just announced a new competition where a team of undergraduate and graduate students can design and build excavation systems that could be used for future lunar exploration. Full competition proposals can include a request for up to $5,000 to cover designing, building, and travel expenses. NASA anticipates funding the first 10 approved team requests. Teams will test their designs in a "head to head" challenge to see which design can excavate the most simulated lunar regolith, or dirt, over a specific timeframe. The competition also involves submittal of a
systems engineering paper, as well as an educational outreach project. The event will be held at the Astronaut Hall of Fame near NASA's Kennedy Space Center, Fla., May 25-28, 2010. For information on the competition and how to apply, go here. Good luck!

(again) for the lack of radio show postings. I do have several months of backlog shows to put here, and hopefully they will be appearing every other day or so until I am caught up. Unfortunately, I did have to move offline all of the 2007 shows due to disk space concerns - if you want them, please email me and I can temporarily put them back online. Again, thank you very much for your patience.

NASA (as does ESA, by the way) sponsors a good number of programs for museums, students, etc. to get people interested in science and engineering. It is currently accepting proposals here (Deadline Oct. 28) for experiments in microgravity conducted by undergraduates, as well as here (for more information, go here) from museums and planetariums for educational activities, and super-efficient aircraft (here).
It also awards prizes for engineering excellence (for example, here), or superb designs of a supersonic aircraft (here). Congrats to the winners, good luck to the applicants, and I'll post information on any further contests as I get them.
To any of you out there who speak Spanish, NASA astronaut Jose Hernandez has recently started his own bilingual twitter, is accepting questions in both English and Spanish here for the next Space Shuttle crew. Enjoy!
Earth, as it travels around the Sun, is passing through the trail of ice and dust left behind by Comet Swift-Tuttle (again), bringing not death and destruction but a very pretty sky show (for free!) known as the Perseid Meteor shower. Go here to read a NASA science article with more details - the Perseid meteor shower is one of most active, and really is a site to behold. Please leave below links to any pictures you take of this event, I'd love to see them. Enjoy!
