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.
The signal appears to emanate from the direction of our neighboring star and cannot yet be dismissed as Earth-based interference, raising the very faint prospect that it is a transmission from extraterrestrial intelligence.
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.
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.
Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. They share some characteristics with supernova explosions and gamma-ray bursts.
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.
The object, called Fomalhaut b, was first announced in 2008. It was clearly visible in several years of Hubble observations that revealed it was a moving dot. Now it has vanished and scientists seek for a plausible explanation.
One of the core assumptions of astronomy is that the universe appears the same in all directions, or it is isotropic. However, a recent study suggests that may not be the case.
It's calculated that, thanks to rapid inflation, the universe may contain more than 1 googol (10^100) stars, and if this is the case then more complex, life-sustaining RNA structures are more than just probable, they're practically inevitable.
A comparative analysis of historical and contemporary astronomical data has resulted in the discovery of approximately 100 star-like objects that unexpectedly vanished. These strange occurrences are likely natural, but scientists say alien technology is a remote possibility.
Scientists have been gathering a growing well of evidence that our universe may be connected via a vast array of large-scale "structures" that seem to reach out across the cosmos to synchronize the movements of galaxies that are separated by vast distances.
