Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing 10 times brighter than the ...
For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery ...
In new images, scientists have gotten the closest look yet at Sagittarius C -- a 'stellar nursery' where clouds of gas and dust have collapsed to form thousands of new ...
At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts -- caused by the death of a massive star -- may ...

NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young ...

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old ...

In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby ...

Leo P, a small galaxy and a distant neighbor of the Milky Way, is lighting the way for astronomers to better understand star formation and how a galaxy grows. Scientists have reported finding that ...

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same ...

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 ...

By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from ...

The night sky has always played a crucial role in navigation, from early ocean crossings to modern GPS. Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies ...

Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present ...

Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky ...

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that ...

Researchers have found evidence of magnetic fields associated with a disc of gas and dust a few hundred light-years across deep inside a system of two merging galaxies known as Arp220. They say these ...

Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut ...

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...

The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the ...

Stunning new photographs by a team of astronomers have revealed a newly forming galaxy that looks remarkably similar to a young Milky Way. The extraordinary images give us an unprecedented picture of ...

Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be ...

Researchers have used the ALMA telescope and found old elliptical galaxies in the universe can form from intense star formation within early galaxy ...
