NASA-funded x-ray instrument settles interstellar debate

July 30, 2014 9:42 am | News | Comments

New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy x-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB.

NASA’s Fermi space telescope finds a “transformer” pulsar

July 23, 2014 9:19 am | Videos | Comments

In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope. It was as if someone flipped a switch on the pulsar.
