How long before BrownDwarfHunters starts, eh? That would be an interesting project!

WISE has found the first-discovered Earth Trojan asteroid. Neat!

Great find! I think that the WISE dataset is gonna keep on giving for many years to come.

on the historical side, Earth Trojans had been searched since at least three decades http://cdsads.u-strasbg.fr/abs/1983BAAS...15..830D
-------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

WISE discovers 100+ brown dwarfs, including 6 Y-dwarfs, one with an estimated surface temperature of 80F.
http://www.nasa.gov/mission_pages/WISE/new...se20110823.html arxiv links First 100 WISE brown dwarfs Y-dwarfs Edited to add. Table 8 in the fist paper lists lower limits of the space density of various spectral types of brown dwarfs. The sum of the values for brown dwarfs T6 or cooler is 0.00455 per cubic parsec. For comparison the value for stars in the solar neighborhood is ~0.1 per cubic parsec. |

NASA To Host News Conference On Asteroid Search Findings WASHINGTON -- NASA will hold a news conference at 1 p.m. EDT on Thurs., Sept. 29, to reveal near-Earth asteroid findings and implications for future research. The briefing will take place in the NASA Headquarters James E. Webb Auditorium, located at 300 E St. SW in Washington.
NASA's Wide-field Infrared Survey Explorer (WISE) mission, launched in December 2009, captured millions of images of galaxies and objects in space. During the news conference, panelists will discuss results from an enhancement of WISE called Near-Earth Object WISE (NEOWISE) that hunted for asteroids. The panelists are: -- Lindley Johnson, NEO program executive, NASA Headquarters, Washington -- Amy Mainzer, NEOWISE principal investigator, NASA's Jet Propulsion Laboratory, Pasadena, Calif. -- Tim Spahr, director, Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, Mass. -- Lucy McFadden, scientist, NASA's Goddard Space Flight Center, Greenbelt, Md. The event will air live on NASA Television and the agency's website. For NASA TV streaming video, downlink and scheduling information, visit: http://www.nasa.gov/ntv The briefing also will be streamed live, with a chat available, at: http://www.ustream.tv/nasajpl2 For more information about the mission, visit: http://www.nasa.gov/wise |
