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.
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.
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.
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.
Magnetars generate the absolute most powerful magnetic fields the cosmos has ever seen – and astronomers have recently spotted a newborn. It appears to be the youngest- ever magnetar ever detected.
Astronomy is advancing to the point where we can see planets forming around young stars. This was an unthinkable only a few years ago. It was only two years ago that astronomers captured the first image of a newly-forming planet.
A Milky Way magnetar called SGR 1935+2154 may have just massively contributed to solving the mystery of powerful deep-space radio signals that have vexed astronomers for years.
