NASA : Andromeda in High-Energy X-rays .- Rayos X de alta energía en Galaxia Andrómeda

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Vista captada por NuSTAR (recuadro) muestra los rayos X de alta energía procedentes en su mayoría de binarias de rayos X, que son pares de estrellas en el que uno de los miembros "muerto" se alimenta de su compañera. El miembro de muertos de la pareja es o bien un agujero negro o una estrella de neutrones. NuSTAR puede recoger siquiera el más leve de estos objetos, proporcionando una mejor comprensión de su población, en su conjunto, en Andrómeda. Los hallazgos en última instancia, ayudar a los astrónomos se reúnen pistas sobre objetos similares en El Universo muy lejano.

NASA's Nuclear Spectroscope Telescope Array, or NuSTAR, has imaged a swath of the Andromeda galaxy -- the nearest large galaxy to our own Milky Way galaxy.

NuSTAR's view (inset) shows high-energy X-rays coming mostly from X-ray binaries, which are pairs of stars in which one "dead" member feeds off its companion. The dead member of the pair is either a black hole or neutron star. NuSTAR can pick up even the faintest of these objects, providing a better understanding of their population, as a whole, in Andromeda. The findings ultimately help astronomers gather clues about similar objects in the very distant universe.

The background image of Andromeda was taken by NASA's Galaxy Evolution Explorer in ultraviolet light.

Andromeda is a spiral galaxy like our Milky Way but larger in size. It lies 2.5 million light-years away in the Andromeda constellation.

NuSTAR is a Small Explorer mission led by the California Institute of Technology in Pasadena and managed by NASA's Jet Propulsion Laboratory, also in Pasadena, for NASA's Science Mission Directorate in Washington. The spacecraft was built by Orbital Sciences Corporation, Dulles, Virginia. Its instrument was built by a consortium including Caltech; JPL; the University of California, Berkeley; Columbia University, New York; NASA's Goddard Space Flight Center, Greenbelt, Maryland; the Danish Technical University in Denmark; Lawrence Livermore National Laboratory, Livermore, California; ATK Aerospace Systems, Goleta, California, and with support from the Italian Space Agency (ASI) Science Data Center.

NuSTAR's mission operations center is at UC Berkeley, with the ASI providing its equatorial ground station located at Malindi, Kenya. The mission's outreach program is based at Sonoma State University, Rohnert Park, California. NASA's Explorer Program is managed by Goddard. JPL is managed by Caltech for NASA.
