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.
Scientists identified the cause of the unusual single-sided pulsation of the star named HD 74423. It is located in a binary star system with a red dwarf - its close companion distorts the oscillations with its gravitational pull.
This star is going to go nova (not supernova) by 2083. V Sagittae is in the constellation Sagitta and is s about 1100 light years from Earth. When the brightening happen, it will be historic. V Sge will appear startlingly bright in the night sky.
Astronomers have found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. These objects look like gas but behave like stars. They are so peculiar that they have been assigned a brand-new class - what astronomers are calling G objects.
Betelgeuse in constellation of Orion is looking markedly faint, the faintest it has been for the 21st century. Betelgeuse is a nearby supernova candidate. Its transformation into Type II supernova could occur 100,000 years from now… or tonight.
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.
In the first observation of its kind, astronomers using the Very Large Telescope in Chile have found evidence of a Neptune-size planet orbiting a white dwarf, the collapsed remnant of a Sun-like star that has run out of nuclear fuel.
Since its 2018 launch, NASA's Parker Solar Probe (record-holder for closest-ever spacecraft to the Sun) has finished three of 24 planned passes through never-before-explored parts of the Sun's atmosphere.
