Stars in distant galaxies are more massive than those in the Milky Way

A team of astrophysicists from the University of Copenhagen has achieved an important result by studying stellar populations in a large sample of galaxies far beyond the Milky Way. The discovery could change our understanding of a wide range of astronomical phenomena, such as those related to the formation of black holes, supernovae and the … Read more

Alcyonea, the largest radio galaxy ever observed

3 billion light-years from our tiny planet lurks a galaxy unlike any we’ve ever seen before. In fact, Alcyonée is a giant radio galaxy measuring 16.3 million light-years across, making it the largest known structure of galactic origin. In Greek mythology, Alcyoneus was one of the greatest giants, the son of Ouranos (Heaven) and Gaia … Read more

A “sleeping” black hole discovered for the first time outside our galaxy

It was estimated that many stellar black holes must exist in pairs with a star, but without tearing material from it and therefore could not signal themselves by shining in the form of X-rays after the accretion of this material. A candidate for such a “sleeping” black hole has just been discovered in the Large … 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

A hidden graveyard of dead stars would envelop our galaxy

Simulations suggest that a significant number of neutron stars and stellar black holes born in the disc or bulge of our Milky Way Galaxy were ejected into orbits outside these structures. So there would be a hidden world of dead stars waiting to be discovered around our galaxy. The theory of the structure and evolution … Read more

Launched in 2004, its purpose was to help identify, locate and observe gamma-ray bursts. But precisely, we learn that on October 9, 2022, he … Read more

Large asteroid impacts on Earth would leave traces on the Moon

Over the past billion years, the Moon and Earth may have been hit simultaneously by clusters of small celestial bodies accompanying at least one major impact, such as the one that caused the Chicxulub astroblem. This is suggested by a recent study of lunar soil samples brought back to Earth by the Chinese Chang’e 5 … Read more

The Noema telescope dedicates its 12 antennas to view the cold universe

For the uninformed hiker launching an attack on the Bure Plateau in the Dévoluy Alpine Massif, arriving at their destination can be surprising. After climbing a steep slope, he discovers at an altitude of 2,550 meters 12 parabolas of 15 meters in diameter facing the sky. If he waits a little, he will even be … Read more
