Astronomers have witnessed a never-seen-before event in observations by ESA’s XMM-Newton spacecraft – a collision between a pulsar and a ring of gas around a neighbouring star. The rare passage, which ...

In 1967, astronomers thought they had finally heard from the neighbors. They intercepted a signal so regular and precise it ...

It may be made from a former star ...

Tiny delays in pulsar signals measured by SETI scientists could aid the search for gravitational waves and extraterrestrial ...

Like anthropologists piecing together the human family tree, astronomers have found that a misfit “skeleton” of a star may link two different kinds of stellar remains. The mysterious object, called ...

Editor’s Note: Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. An international team of astronomers has ...

Hiding within the huge catalog of newly found pulsars are several "spider pulsars," or neutron stars that devour their companion stars. When you purchase through links on our site, we may earn an ...

Pulsars are one of the strangest celestial bodies in space. These cosmic lighthouses emit periodic bursts of radiation from their magnetic poles, and now a team of researchers claim they have detected ...

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons ...

A rapidly spinning neutron star that sweeps beams of radiation across the universe like a cosmic lighthouse has been discovered by U.S. Naval Research Laboratory (NRL) Remote Sensing Division intern ...

Some stars never really die. Pulsars are the undead magnetized cores of massive stars that have met their end in a supernova. They rotate furiously, spewing jets of electromagnetic radiation from ...
