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

Messenger sends back photos of never-before-seen Mercury surface

The MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) spacecraft, launched on August 3, 2004 is the first mission to visit Mercury in over three decades. Yesterday, at 21:55 UTC, the probe flew by Mercury 228 km above the surface with the relative speed of 5.28 km/s. The third and final gravity assist slowed down the spacecraft and placed it on a trajectory for Mercury Orbital Insertion (MOI) on March 18, 2011.

Yesterday, as the spacecraft approached Mercury for the mission's third flyby of the Solar System’s innermost planet, MESSENGER captured this striking view. This WAC image shows portions of Mercury's surface that had remained unseen by spacecraft even after the three flybys by Mariner 10 in 1974-75 and MESSENGER's two earlier flybys in 2008 - Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington
