ESA Signs Astro-H Agreement With JAXA
2012-04-11 04:04:52

An agreement was signed by ESA and the Japanese Aerospace Exploration Agency (JAXA) for cooperation on Astro-H, an important mission that will provide a unique opportunity for probing extreme phenomena in the Universe. Astro-H will study astrophysical objects including black holes and neutron stars, explore the non-thermal Universe, and investigate the large-scale structure of the Universe and its evolution. The agreement was signed on 16 March by Prof. Alvaro Giménez...

Studies of two supernova remnants using the Japan-U.S. Suzaku observatory have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the explosions. Even after thousands of years, gas within these stellar wrecks retain the imprint of temperatures 10,000 times hotter than the sun's surface. "This is the first evidence of a new type of supernova remnant -- one that was heated right after the explosion," said Hiroya Yamaguchi at the Institute of Physical...

The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. For the first time, Suzaku has detected X-ray-emitting gas at a cluster's outskirts, where a billion-year plunge to the center begins. "These Suzaku observations are exciting because we can finally see how these structures, the largest bound objects in the universe, grow even more massive," said Matt George, the study's lead author at the University of...

A pioneering X-ray detector developed at NASA'S Goddard Space Flight Center (GSFC) in Greenbelt, Md. will launch on board the new Astro-E2 space observatory. Astro-E2's primary instrument is the high-resolution X-ray Spectrometer (XRS), developed jointly by GSFC and the Japan Aerospace Exploration Agency (JAXA) Institute of Space and Astronautical Science (ISAS). The XRS measures the heat created by the individual X-ray photons (light particles) it collects. To sense the heat of a single...

TOKYO (AP) -- Japan's space agency said Wednesday it plans to launch a satellite carrying X-ray telescopes into Earth's orbit as early as next month to study black holes and far-flung galaxies. The launch of the Astro-EII satellite was planned between June 26 and July 15 but could be delayed until August, said the Japan Aerospace Exploration Agency, or JAXA, in a statement on its Web site. JAXA said the satellite will carry five X-ray telescopes - which detect traces of light - to study the...
