A radio telescope in Australia recently captured a stunning image of NGC 4632, a galaxy some 56 million light-years from Earth. The image reveals a halo of cool hydrogen orbiting perpendicular to the galaxy itself.
According to a new analysis of a type of galaxy known as a blazar, the best explanation for unusual changes in their glow is a pair of supermassive black holes locked in a decaying orbit.
Astronomers detected the most distant galactic magnetic field so far. The galaxy is called 9io9. Its light has to travel travel more than 11 billion years to reach us, from a time when the universe was a young 2.5 billion years old.
The bubble is 10,000 times wider than the Milky Way and located 820 million light-years from our own galaxy. The astronomers have called their bubble Ho’oleilana – meaning “sent murmurs of awakening”.
The galaxy, called JD1, is seen as it was when the universe was only 480 million years old, or 4% of its present age.
International research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.
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.
