Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical ...
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...
Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
For the third time in 35 years, the black hole at the center of the galaxy IC 3599 has erupted, and this time, astronomers were watching it closely. IC 3599, a galaxy roughly 280 million light-years away, has flared this ...
For more than a century, astronomers have puzzled over a strange discrepancy in the historical record. Theta Eridani, a modest star in the constellation Eridanus, is the third-brightest star in its constellation, with a magnitude ...
An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint server arXiv, deliver ...
Researchers in the U.S. have carried out the most stringent tests to date of the idea that an ultraviolet glow in the atmospheres of giant planets could partly arise through the indirect interaction between dark matter and ...
Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. ...
European astronomers have conducted optical and radio observations of an enigmatic radio source designated GRS 0917+75. As a result, they found that GRS 0917+75 is a giant radio galaxy and determined its properties. The new ...
Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported ...
