There’s a celestial body in the galaxy messier 82also known as the Cigar Galaxywhich emits 10 million times more light than the Sun. According to the laws of Physics,this is only possible if the body is about to explode.
In new research, a Canadian-led team of astronomers turned up another 25 repeating FRBs, doubling the number already discovered.
Scientists have unlocked one of the biggest mysteries of quasars—the brightest, most powerful objects in the universe—by discovering that they are ignited by galaxies colliding.
The James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed just 320 million years after the Big Bang when the universe was still in its infancy, new research said on Tuesday.
One newly discovered dwarf galaxy, FAST J0139+4328, located a mere 94 million light-years away is barely emitting any light at all. The galaxy seems to be made up almost entirely of dark matter.
Astronomers have recently released new images of the Milky Way that offer an unprecedented look at an enormous slice of the galaxy, complete with star clusters, clouds of cosmic dust and the supermassive black hole Sagittarius A*.
Researchers from Montreal and India have captured a radio signal from the most distant galaxy so far at a specific wavelength known as the 21 cm line, this is the first time this type of radio signal has been detected at such a large distance.
A Japanese scientist has shown that large gamma-ray-emitting bubbles around the center of the Milky Way were produced by fast, outward-blowing winds and an associated "reverse shock."
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.
James Webb Space Telescope has captured light emitted by the galaxies more than 13.4 billion years ago, which means the galaxies date back to less than 400 million years after the Big Bang, when the universe was only 2 % of its current age.
Scientists have proved that the source of high-energy neutrinos is a special kind of supermassive black holes called blazars.
NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb'nas First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
More than three years after the release of the first-ever image of a black hole, scientists from the Event Horizon Telescope (EHT) shared an image of Sagittarius A* — the supermassive specimen sitting at the center of our own Milky Way galaxy.
Astronomers completed a 40-hour long observation of an ultra-diffuse dwarf galaxy and discovered no traces of dark matter. Galaxies without hints of dark matter had been previously discovered though these remain rare anomalies.
New research has just answered one of the fundamental questions about our universe: Why did some of the oldest, most massive galaxies go quiescent early in their formation? The answer, we now know, is because they ran out of cold gas.
