For the first time ever, astronomers have witnessed a black hole swallowing a star. The event took place 150 million years ago in a pair of colliding galaxies called Arp 299. The black hole was 20 million times larger than our own Sun, and was seen consuming a body twice the size of our stellar companion.Read More Black Hole Seen Eating Star for First Time Ever
An asteroid orbiting backwards around the Sun may have come from another solar system, according to astronomers in France.
Asteroid 2015 BZ509 is roughly two miles across, and orbits the Sun at roughly the same distance as Jupiter. Computer simulations suggest the object may have joined our planetary family four-and-a-half billion years ago, just as the Earth and other planets were being formed.
The earliest stars in the Universe formed just 250 million years after the big bang, according to astronomers working at the ALMA facility in Chile. Researchers also discovered the oldest oxygen ever detected, from just 500 million years after the creation of the Universe. These discoveries push back the time when astronomers believe starlight first filled the Cosmos.Read More First Stars Formed Just 250 Million Years After Big Bang
