Some of the biggest galaxies in the universe stopped making stars billions of years ago, and even today, no one fully understands why. This mystery is puzzling because many of these galaxies still ...

For decades, astronomers have known that supermassive black holes lurk at the hearts of essentially all large galaxies, occasionally feasting on infalling material and burping out powerful jets. But ...

Astronomers are drawing attention to a Christmas Tree-shaped cluster of stars glowing inside one of the Milky Way’s most active stellar nurseries. Known as the Cosmic Christmas Tree, the cluster sits ...

Researchers from Yunnan University, the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, and the National Astronomical Observatory of Japan have unveiled new insights into ...

NASA’s Nancy Grace Roman Space Telescope is scheduled to conduct the Galactic Plane Survey to map the Milky Way’s structure and examine star formation across the galaxy. The survey, Roman’s first ...

Astronomers have made a surprising discovery about NGC 6789, an isolated dwarf galaxy located 12 million light-years away in the constellation Draco. Despite residing in the Local Void—one of the ...

About 12 million light years away lies an impossible galaxy. Over the last 600 million years, its core has been forming new stars – but there is no apparent source for the fuel that has fed that star ...

Also known as the Seven Sisters and Messier 45, the Pleiades — an open star cluster about 440 light-years from Earth in the constellation of Taurus — constitutes the bound core of a much larger ...

A telescope tasked with making the largest-ever map of the universe has confirmed a harsh, if unsurprising, truth: Nothing lasts forever — not cold November rain, or even the cosmos itself. Using a ...

Imagine a universe that barely exists—just fractions of a second old, too young to look anything like the cosmos we know today. Now, picture black holes, boson stars, and even something as outlandish ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...
