Ghosts of the Future: First Giant Structures of the Universe Hold 800 Trillion Suns – Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster yet seen at a distance of 7 billion light-years. The cluster (designated SPT-CL J0546-5345) weighs in at around 800 trillion Suns, and holds hundreds of galaxies. –Science Daily

Confirmed Exoplanets Could Reach 500 by the End of This Month – If it seems like a new extrasolar planet is discovered every week these days, that’s because there is. In fact, the rate is actually faster than one per week – 70 have been discovered thus far this year alone, bringing the overall tally of confirmed exoplanets at 494. At that pace we very well might hit exoplanet number 500 before the end of this month. -Clay Dillow / PopSci

Being in space can change the way you view the Earth – That was certainly the case for the Apollo 8 crew who produced the iconic image of our planet emerging from behind the limb of the Moon –Jonathan Amos / BBC

Hubble and Rosetta unmask nature of recent asteroid wreck – High-resolution images from the Hubble Space Telescope and a rare view obtained, from a unique perspective, by the Rosetta spacecraft provide a comprehensive picture of P/2010 A2, a puzzling body in the asteroid main belt. –ESA

Camera That Saved Hubble Leaves Nest for Good – NASA’s Wide Field and Planetary Camera 2 was loaded for transport from the Jet Propulsion Laboratory, Oct. 13, 2010. – NASA/JPL

Gliese 581g, that new “goldilocks” exoplanet we got excited about a few weeks ago, might not exist – A group of Swiss astronomers announced yesterday at the International Astronomical Union’s annual meeting in Turin, Italy, that they couldn’t detect the “goldilocks” exoplanet found by U.S. researchers a few weeks ago. –Discovery Blogs

SOHO sheds new light on solar flares – After detailed analysis of data from the SOHO and GOES spacecraft, a team of European scientists has been able to shed new light on the role of solar flares in the total output of radiation from our nearest star. Their surprising conclusion is that X-rays account for only about 1 per cent of the total energy emitted by these explosive events. –ESA SOHO

Giant Star Goes Supernova, Smothered by its Own Dust – Astronomers using NASA’s Spitzer Space Telescope have discovered that a giant star in a remote galaxy ended its life with a dust-shrouded whimper instead of the more typical bang. –JPL/NASA

The six-member crew of the next space shuttle mission, STS-133, arrived at NASA's Kennedy Space Center on Oct. 12 to participate in a full launch dress rehearsal, known as the Terminal Countdown Demonstration Test, and related training. The test provides an opportunity for the crew and ground teams to participate in various simulated countdown activities, including equipment familiarization and emergency exit training. Shuttle Discovery's crew members are Commander Steve Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Michael Barratt, Tim Kopra and Nicole Stott. Discovery is targeted to launch Nov. 1 on its final scheduled flight. - Credit: NASA TV
