After 16 years in space, NASA’s Rossi X-ray Timing Explorer (RXTE) has made its last observation. The satellite provided unprecedented views into the extreme environments around white dwarfs, neutron stars and black holes.
RXTE sent data from its last science observation to the ground early on Jan. 4. After performing engineering tests, controllers at NASA’s Goddard Space Flight Center in … Read the rest of this article
Sensors destined for ESA’s LISA Pathfinder mission in 2014 have far exceeded expectations, paving the way for a mission to detect one of the most elusive forces permeating through space – gravity waves.

The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays. The observations from NASA’s Chandra X-ray Observatory will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity.

Galileo first turned his telescope to the heavens in 1609, marking the dawn of modern astronomy. To commemorate 400 years of exploring the universe, 2009 has been designated the International Year of Astronomy.
In conjunction with Galileo’s birthday on Feb. 15, NASA is releasing images from its Great Observatories — the Hubble Space Telescope, Spitzer Space Telescope, and Chandra X-ray … Read the rest of this article
NASA has made a decision to restart an astronomy mission that will have greater capability than any existing instrument for detecting black holes in the local universe.
The Nuclear Spectroscopic Telescope Array, or NuSTAR, will expand our understanding of the origins and destinies of stars and galaxies. NASA had stopped the study effort on the NuSTAR mission in 2006 due … Read the rest of this article
