XMM-Newton discovers X-ray nova and unique, pulsating white dwarf in the
Andromeda Galaxy

"In its first look at the Andromeda Galaxy, known as M31, the X-ray
Multi-Mirror satellite observatory has revealed several unusual X-ray
sources. In examining new satellite data, an international team of
scientists, including researchers at the United States Department of
Energy's Los Alamos National Laboratory, discovered an unusually bright
spot created by an enormous X-ray nova outburst. Another mysterious object
has been found as well: one of the "coolest" sources of the central region
appears to be a luminous white dwarf with an extremely soft energy spectrum
and the shortest X-ray pulsation period seen to date."

New Map of the "Nearby" Universe Reveals Large-Scale Structure of Galaxies

"Astronomers presented a new view of the "nearby" universe, probing the way
that galaxies cluster together over distances of hundreds of millions of
light years. The new map for the first time covers the whole sky, including
the large portion ordinarily hidden by our own galaxy, the Milky Way, and
reveals a complicated network of galaxies surrounding us."
