galaxies

Astronomers recently announced the discovery of a galaxy located a record-breaking 13.5 billion light years away when the universe was in its infancy.

Astronomers say they may have solved the decades-old mystery of why some galaxies stop creating stars, causing them to die.

Prolific star hunter Filipp Romanov, 24, previously discovered 80 variable stars, planetary nebula, and binary stars, but SN 2022bsi is his first supernova.

Images of the Cartwheel galaxy located around 500 million light-years from Earth show a massive star erupting in a supernova that will disperse heavy elements throughout the Universe.

Almost 126 years to the day since its discovery, an image taken by the Hubble telescope shows the three-way galactic merger IC 2431.

The black hole powers a region roughly the size of the solar system that is more luminous than

Researcher Martijn Oei didn't know how impressive the 16 million light-years long galaxy was until another expert told him: "Congratulations, this is the largest radio galaxy ever found!"

The catalog represents an important development in "galactic archeology" revealing a multitude of stars that formed in the early universe.

Astronomers found that parts of the galaxy where stars are born were being protected from these powerful outflows thanks to its structure.

Some massive stars travel distances that should take many of their relatively short lifespans to traverse. Astronomers think they now know how this happens.

The supermassive black hole at the heart of the Centaurus A galaxy blasts out powerful radio jets as it ejects material into space at near light speed.

The results could help astronomers understand violent cosmic events in which black holes devour stars and launch powerful jets of material at near light speed.

The void is located 170,000 light-years from Earth, within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud.

New research has revealed that galaxies are being sent to cosmic graveyards because a crucial ingredient needed for star formation is being snatched from them.

The new research suggests a modified theory of gravity that can explain the large-scale structure of the Universe.

The Hubble telescope has found that star formation happens in sudden bursts giving clues about the Universe's bumpy start.

The material that billows out from feeding supermassive black holes stretches for thousands of light-years "impacting anything that stands in their way."

The fact that the solar system could be traveling through a highly magnetized filament in space may also explain mysterious rope-like structures in the sky.

Scientists found the elusive black hole with a mass 10,000 times that of the Sun after it gave off the powerful X-ray flare.

The galaxy, which is 9.4 billion light-years from Earth, appeared to the Hubble Space Telescope as a cosmic illusion known as an Einstein Ring.

Using the Hubble Space Telescope, astronomers have made findings that could redefine what we know about the evolution of galaxies

Scientists can now hold the birthplace of stars in their hands, and study them in unprecedented detail.

The discovery could change the way astronomers measure the ages of stars in the Milky Way, and means previous estimates could be off by as much as a billion years.

"There are likely more weird ones out there, and we need to think about how to look for them," said Davy Kirkpatrick, an author of the study.

The image shows Centaurus A's curling tendrils of dust and gas in never-before-seen detail.

The star cluster is located in the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way.

"We had never seen anything like it before, and we had no idea what they were," said astrophysicist Ray Norris.

Astronomers peered at a galaxy hundreds of millions of light-years away and found evidence it is recycling lost gases.

The galaxies are located approximately 763 million light-years away in the constellation of Lynx.

The galaxies are located hundreds of millions of light years away from Earth and are leaving a trail of stars and dust as they merge.
