The Simultaneous Merging of Giant Galaxies

Scientists proved for the first time that the galaxy NGC 6240 contains three supermassive black holes. The unique observations show the black holes close to each other in the core of the galaxy. The ... read more

First Evidence of Bio-Essential Sugars in Meteorites

A new study has discovered meteorites containing RNA sugar, ribose, and other bio-important sugars; the first direct evidence of bio-essential sugars' delivery from space to the ... read more

Astronomers Discover Most Energetic Gamma-Ray Burst Ever

Gamma-ray bursts are the most energetic phenomenon known to humankind. Although short-lived, they outshine stars and even galactic quasars. They usually display energies in the region of tens of ... read more

Caught in the Act: MeerKAT Telescope Spies Stellar Flare

The MeerKAT radio telescope in the Northern Cape of South Africa has discovered an object which rapidly brightened by more than a factor of three over a period of three weeks. This is the first new ... read more

Outback Telescope Captures Milky Way Center, Discovers Remnants of Dead Stars

A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the galaxy in which we live, the Milky Way. The image from the Murchison Widefield Array (MWA) ... read more

NASA's TESS Helps Astronomers Study Red-Giant Stars, Examine a Too-Close Planet

Astronomers have been studying two red-giant stars -- older, 'retired' stars no longer burning hydrogen in their cores. The study details an interesting case of planetary evolution and ... read more
