The European Space Agency’s (ESA) XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10,000 times its normal brightness. Astronomers believe the outburst was ...

Sweet new research suggests that some neutron stars have stiff mantles and soft cores, while others have soft exteriors and stiff hearts, just like different types of chocolates. When you purchase ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...

In 1987, astronomers had an incredible front-row seat to a cosmic event that maybe isn’t rare, but rarely happens near us. Just 168,000 light-years away, on February 23 of that year, a star in the ...

WASHINGTON, April 24 (Reuters) - Magnetars are among the universe's most extreme objects - a class of the compact stellar remnants called neutron stars that possess immensely strong magnetic fields.
