A ‘glowing’ bubble of gas circles the Milky Way’s giant black hole at breakneck speed

On May 12, 2022, the very first image of the central black hole in our galaxy, Sagittarius A*, was revealed. Scientists have since continued their studies of this supermassive star. And by observing data from the Alma radio telescope, they made a surprising discovery: a bubble of glowing gas is orbiting the black hole at … Read more

While studying the supermassive black hole at the center of our galaxy, Sagittarius A*, scientists made a strange discovery: a bubble of glowing gas spinning around it at very high speed! A phenomenon that is explained by the eruption of black holes. On May 12, 2022, the very first image of our central black hole … Read more

The Alma radio telescope is making progress on the trail of galaxy killers

One of the great mysteries of astrophysics concerns the death of galaxies, that is, we find that some of them have not formed stars for billions of years, largely emptied of the necessary material. We suspected explosions of supernovae or movements in the intergalactic medium, in the clusters that blew the gas of the galaxies. … Read more

There would be many habitable Tatooins in the galaxy

There are so manystars in our Universe. So many planets too. Looking for traces of extraterrestrial life is a bit like looking for a needle in a haystack. Aside from perhaps focusing primarily on planets that resemble the only planet we know has allowed life to evolve: our Earth. It is therefore astronomers seek heaven … Read more
