Visual Astronomy 3 Jul 2009, 07:28 UTC On July 22nd, 2009, viewers in India and Southeast Asia will be treated to a total solar eclipse. With an incredibly long totality of 6 minutes and 39 seconds, this solar eclipse will be the longest solar eclipse until 2132! This eclipse will be visible starting in India, moving through Nepal, Bangladesh, China, and the southern end of Japan, finally ending in the South Pacific. To see a detailed map of the total eclipse's path, see the maps below.The eclipse's path through India, Nepal, Bangladesh, and Bhutan.The eclipse's path through China.The eclipse's path through southern Japan.For more detailed maps, see NASA's page on the eclipse.SAFETY FIRST!Although you will want to look at this eclipse, DO NOT LOOK AT A SOLAR ECLIPSE without proper safety equipment. Doing so can cause permanent and irreversible eye damage and possibly blindness.In order to safely view this eclipse use a pinhole eclipse viewer. Here's how to make one for cheap.Eclipse Predictions by Fred Espenak, NASA's GSFCClear skies!
Space Fellowship 3 Jul 2009, 07:19 UTC With NASA’s Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. In two studies published in the July 2 edition of Science Express, international teams have analyzed gamma-rays from two dozen pulsars, including 16 discovered by Fermi. Fermi is the first spacecraft able to identify pulsars by their gamma-ray emission alone.A pulsar is the rapidly spinning and highly magnetized core left behind when a massive star explodes. Most of the 1,800 cataloged pulsars were found through their periodic radio emissions. Astronomers believe these pulses are caused by narrow, lighthouse-like radio beams emanating from the pulsar’s magnetic poles. “Fermi has truly unprecedented power for discovering and studying gamma-ray pulsars,” said Paul Ray of the Naval Research Laboratory in Washington. “Since the demise of the Compton Gamma Ray Observatory a decade ago, we’ve wondered about the nature of unidentified gamma-ray sources it detected in our galaxy. These studies from Fermi lift the veil on many of them.”The Vela pulsar, which spins 11 times a second, is the brightest persistent source of gamma rays in the sky. Yet gamma rays — the most energetic form of light — are few and far between. ...

The Night Sky Guy 2 Jul 2009, 18:38 UTC According to the first findings from the Phoenix Mars Lander mission, snow and water-ice clouds play a crucial role in the exchange of water between the atmosphere and surface of Mars, which suggests that the Red Planet is even more like Earth than previously thought. The surprise discovery of Martian snow in 2008 by the Canadian-built weather station on NASA’s Phoenix Mars lander helps explain how the water cycle on Mars behaves, especially the seasonal increase of the Martian polar caps in winter and their consequent shrinking in summer.
Cosmic Diary 2 Jul 2009, 16:32 UTC For so many people, science is something hard to understand. Only genius who could understands math, physics and all science subject including astronomy. And those genius proof themselves as the best when they win a gold medal in science olympiads. We often heard.. young people in Indonesia are talented and we could compare them with other country since many of them win a medal in olympiads.
NASA Watch 2 Jul 2009, 16:20 UTC Last few days remaining to win a scholarship to attend IAC'09 in Korea through SGAC "Move An Asteroid 2009" Competition! "Move An Asteroid 2009" is an International Student and Young Professional Technical Paper Competition. The competition accepts individuals or team (maximum of 3 individuals) under the age of 33 to submit a 3-10 page technically detailed paper on a unique and innovative concept for deflecting an asteroid/comet with at least 50 metre of diameter.Please visitwww.spacegeneration.org/asteroid for more information. The deadline for entries is 26th July 2009. The winner will be sponored to attend IAC and SGC '09 in Daejeon, South Korea. The entries should be send to firstname.lastname@example.org"
Professor Astronomy 2 Jul 2009, 15:40 UTC When reading about scientific discoveries, it is always important to remember Professor Astronomy's Discovery Law: The last person to discover something gets the credit. Yesterday, a news story was released on a nice bit of research that is "the first solid evidence of a new class of medium-sized black holes." Only many other astronomers who have claimed to discover medium-sized black holes would argue that they had already discovered the first solid evidence of such things.
Universe Today 2 Jul 2009, 15:38 UTC Although current astronauts are Twittering and blogging from space, it's a cumbersome process as the ISS, shuttle and Soyuz do not have internet access. Instead, they have to downlink their information to mission control, where someone posts it to the web. But if future commercial space travelers or astronauts living on the Moon want to blog, Tweet and share their experiences real-time, will it be possible? Well, a group of engineers are working on applying the same wireless systems that keep our mobile phones, laptops and other devices connected to the web to a new generation of networked space hardware. They say that wireless technologies will likely be important part of future space exploration, not only for human communication but for transfer of data and commands.
Astrocast.TV Blog 2 Jul 2009, 13:53 UTC In a paper to be published in the Astrophysical Journal Letters, available online now here, astronomers have announced the uncovering of new evidence in support of a very early sunspot cycle in the 18th century. The authors inform the community that this “brings the attention of the scientific community to the need of revisingthe sunspot series in the 18th century.”
