ESA's XMM-Newton has found a pulsar - the spinning remains of a once-massive star - that is a thousand times brighter than previously thought possible.
Neutron stars are one possible suspect responsible for an abundance of positrons in the Milky Way. Now astronomers have caught one red handed.
Just 4,000 light-years from Earth is a strange, star-sized object. It’s been observed by radio telescopes, but astronomers aren’t sure what it is. They call it a long period transient.
By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind fast radio bursts after all. The bursts may come from a highly magnetized, isolated neutron star - magnetar.
International team of astronomers found a star 100 times larger than our sun that nearly disappears from the sky every few decades. They also have no idea why it does so. This could be a new class of stars.
Astronomers studying data from NASA’s TESS mission have found a remarkable sextuple star system featuring three gravitationally bound eclipsing binaries.
Researchers using the Hubble Space Telescope observed one of the closest globulars to Earth – NGC 6397 and were surprised to find signs of multiple stellar-mass black holes.
The star in question is called Swift J1818.0–1Th607 is what's known as a magnetar, though, none of the magnetars have ever been observed pulsing in quite the same way as Swift J1818.0–1607.
A mysteriously dimming star located about 1,480 light-years away in the constellation of Cygnus and known as Tabby's star is, in fact, a binary stellar system, made up of a F-type star and a smaller red dwarf star.
Only 31 magnetars ( type of neutron star that has the strongest magnetic field ) have even been discovered and recently astronomers have found an extremely unique object that is both a magnetar and a pulsar.
Until now, the source of Fast Radio Bursts was a mystery. Now astronomers at multiple institutions have pinpointed the FRB spotted in the Milky Way and conclude it most likely was generated by a magnetar.
The record-breaking field was discovered at the surface of a neutron star called GRO J1008-57 with a magnetic field strength of approximately 1 BILLION Tesla. For comparison, the Earth’s magnetic field is about 1/20,000 of a Tesla.
Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.
The star with the smallest orbit is known as S62. Its closest approach to the black hole has it moving more than 8% of light speed. S62 orbits our supermassive black hole Sagittarius A every ten years.
Can a massive star collapse into a black hole without first exploding in a supernova blast? That’s at least one explanation for the disappearance of a star 2.5 mil times brighter than the sun in a dwarf galaxy 75 mil light years away.
