Astronomers spotted a magnetic explosion on the surface of the sun unlike anything they've ever seen before. Although it was initially theorized about 15 years ago, this was their first direct observation of it thanks to NASA's Solar Dynamics Observatory.
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.
Data obtained by VLT showed evidence of massive stars bursts billions of years ago in the galaxy’s center. The more recent burst was so intense that resulted in 100,000 supernova explosions. These findings are inconsistent with our notions that stars formed continuously in our galaxy.
CHEOPS stands for the Characterizing Exoplanet Satellite. It’s a partnership between ESA and Switzerland, with 10 other EU states contributing. Its mission is not to find more exoplanets, but to study the ones we already know of.
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.
Astronomers have spotted an unusually distant star-forming galaxy, the light of which took a whopping 13 billion years to reach Earth. Perhaps most incredibly, however, the galaxy was observed directly, without gravitational lensing.
Comet 2I/Borisov is only the second interstellar object known to have passed through the solar system. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star.
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.
Astronomers have measured a 40 billion solar mass black hole in the Holm 15A galaxy. Their results could lead to even more massive black holes.
The discovery of Metallosphaera sedula - the bacteria that eats meteorites not only invites speculation on how terrestrial life could survive off world, it offers insight into how early biology could have received key nutrients through space rocks.
On Thursday, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral in Florida bound for the International Space Station. It marked SpaceX’s 19th trip to the space station and the company's final trip to the station for the decade.
We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.
Extensive observations indicated the presence of three supermassive back holes in the three galaxies NGC 6240 that are the process of merging. Up until now, such a concentration of supermassive black holes had never been discovered in the universe.
Researchers have observed a gamma-ray burst with an afterglow that featured the highest energy photons -- a trillion times more energetic than visible light - ever detected in a burst.
