Orienteering for Robots: Algorithm Could Aid Navigation, Scene Understanding

April 10, 2014 2:22 pm | by Larry Hardesty, MIT | News | Comments

Suppose you’re trying to navigate an unfamiliar section of a big city, and you’re using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns and, for a while, you lose sight of your landmarks. When they reappear, in order to use them for navigation, you have to be able to identify them as the same buildings you were tracking before — as well as your orientation...

Monster El Gordo Most Massive Galaxy Cluster Ever Seen

April 10, 2014 2:14 pm | by NASA | News | Comments

NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname — El Gordo (Spanish for "the fat one"). By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to be as much as 3 million billion times the mass of our sun.

Fermi Data Tantalize with New Clues to Dark Matter

April 4, 2014 4:30 pm | by Francis Reddy, NASA's Goddard Space Flight Center | News | Comments

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources
