Please Donate Aid to Myanmar (Burma)

As you might have heard in the news and can see here, Myanmar (Burma) was devastated by Cyclone (Hurricane) Nargis this Saturday. The damage is quite extensive - I know personally because my wife is Burmese, she in fact is in Yangon (Rangoon) now helping her parents with the clean-up and I will be joining her this weekend for two weeks. If you can, please done money here to the American Burmese Buddhist Association, an organization which runs Burmese Buddhist monasteries in the United States. The monks at these monasteries are sending the money directly to people in Burma who need the money - no worries about it being appropriated by the military government or going into the pockets of some fund administrator. Thank you.

PS. Myanmar is the name for Burma in Burmese, the language of the largest ethnic group in the country. (In fact, in Burmese the name of the country, people, and language is Myanmar.) Burma was the name given to the region by the British.

Fly through the Earth's Ionosphere

NASA has recently released a real-time model of the ionosphere, the upper-most layer of the Earth's atmosphere where atoms are ionized largely by ultra-violet light from the Sun, available for Google Earth here. For more information on this model, and the importance of the ionosphere, read this article. Enjoy!

April 30th Radio Show - Mercury and Venus

The April 30th radio show is now online, available here. Our tour of the Solar System continues with the two innermost planets, Mercury and Venus. I made a mistake on-air when I discussed why it is so hard to get a spacecraft from Earth to Mercury, and have added an errata to the mp3 available above, so even if you heard this show live I strongly encourage you to listen to the mp3 so you can hear the correct information. On this program, I also covered:

• News: Solar flare on Sun observed to trigger a "tsunami"-like shock wave through Sun's atmosphere as well as launch a coronal mass ejection on April 26; congratulation to Dr. Adam Riess (JHU/STScI) for being elected to the American Academy of Arts and Sciences, to the Galaxy Evolution Explorer (GALEX) team for successfully maintaining this UV telescope in space for 5 years; happy birthday to the Hubble Space Telescope, which celebrated 18 years from launch on April 27th - to celebrate, pretty pictures of 59 colliding galaxies were made public (link); assembly of the Herschel telescope, an European space-based infrared telescope, has been completed; DAMA/LIBRA experiment in Italy has claimed to directly detect "dark matter" on Earth again, other groups skeptical; shoulder motor on Mars rover Opportunity experiencing technical difficulties (link); Austria declares intention to join European Organization for Astronomical Research in the Southern Hemisphere (ESO); astronauts interviewed live by students on April 30 (link); NASA's Jet Propulsion Laboratory (JPL) to have an open house May 3-4
• Wednesday Morning Astronomer, a response to the astronomy content in Gregg Easterbrook's column "Tuesday Morning Quarterback" (available here) - yes, Gamma Ray Bursts (GRBs) are absolutely amazing but, no, I don't think a flurry of them were timed to mark the death of Arthur C. Clarke. I know it was a joke, but...
• Calendar of upcoming events in the greater Poughkeepsie/New York City area
• Mercury: Small rocky planets very close to the Sun, very poorly understood relative to many of the other planets in the Solar System since it is hard to observe and hard to send spacecraft to. NASA's recently launched a spacecraft to Mercury called MESSENGER, which has already flown by Mercury once. During this flyby, it imaged several craters which have dark rims, a crater with a shiny bottom, a crater wit radial spokes coming out of its center, and a very weak magnetic field emanating from its surface. The origins of these features are not known, and hopefully with more data obtained by MESSENGER after it enters Mercury's orbit in the March 2011 people will be able to figure it out. Also, scalloped-edge cliffs (called "lobate scarps") on Mercury's surface possible result of very thin mantle underneath Mercury's crust (link)
• Venus: Has, by far, the thickest atmosphere of any of the Rocky Planets in the Solar System. Recent results include the discovery of a variable bright haze layer, likely composed of sulfuric acid, at the top of its atmosphere whose origin is unknown; possible evidence for active volcanos on Venus's surface detected by the European Space Agency's Venus Explorer (link); Carbon Monoxide plays a more important role in atmosphere of Venus and Mars than previously thought (link); eye of a hurricane observed at the south pole of Venus observed to flicker and change shape within a matter of days (link); it is possible that Venus was created from the collision between two very large objects in early Solar System, could explain why - despite similar mass and distance from the Sun - Earth and Venus or so different (link); another possibility for these difference is lake of plate tectonics on Venus (link).

Hope you enjoyed, and thank you very much for listening. As always, please leave below or email any questions, comments, or concerns you might have.

2008 World Science Festival in New York City

The first ever (but hopefully annual) World Science Festival will be held all around New York City between May 28 and June 1. There are a lot of really interesting events, for a complete listing, go here.

Mercury visible

Since Mercury is so close to the Sun, it is often hidden in the Sun's glare and therefore very difficult to see from the Earth. However, this Tuesday evening, (May 6th), just after sunset the crescent Moon glides by Mercury in the darkening western sky. A sky map and photos are available at http://spaceweather.com, which was the sources of much of this information.

eta Aquarid Meteor Shower

Courtesy of spaceweather.com:

"ETA AQUARID METEOR SHOWER: If you see a meteor flit across the sky tonight, it could be a piece of Halley's Comet. Earth is crossing a stream of dusty debris from Halley and this is causing the annual eta Aquarid meteor shower. Sky watchers in the tropics and southern hemisphere (where the shower is most intense) could see as many as 70 meteors per hour during the dark hours before dawn on Monday, May 5th, and Tuesday, May 6th. The show is diminished at northern latitudes where rates may be 15 meteors per hour or less. Check http://spaceweather.com for sky maps and more information."

Happy meteor shower watching!

Want to learn what it takes to be an astronaut?

Well, on May 7th NASA astronauts Dan Tani of Illinois and Suni Williams of Massachusetts, will be answering questions on what it takes. Tani will be available from 5 to 8 a.m. CDT and Williams will be available from 4 to 6 p.m, as part of NASA's recruitment for its 2009 astronaut class (the deadline for applications is July 1.). NASA's media channel will be used to conduct the interviews. The channel is located on satellite AMC 6, transponder 5C, which is located at 72 degrees west, downlink frequency 3785.5 Mhz, vertical polarity, FEC of 3/4th, symbol rate 4.3404 Mbaud. For more information on astronaut recruitment, go here, and for NASA TV, go here. Enjoy!

2008 U.S. Astronaut Hall of Fame Induction

I didn't realize there is a US Astronaut Hall of Fame but there is one, and it's induction ceremony will be broadcast live, this Saturday, beginning at 3 PM EDT on NASA TV. Enjoy!
