There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there is another class […]

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what […]

Astronomers have used the James Webb Space Telescope to catch an extraordinary glimpse of a massive galaxy taking shape in the early universe. They identified a compact group of at least six galaxies that are […]

Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon […]

Astronomers have discovered a “remarkable” bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published today in Monthly Notices of the […]

Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results of the observations, […]

A stunningly concentrated and hefty galaxy cluster, from a time in the universe’s history when such massive structures aren’t expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of three […]

The Bullet Cluster has so far been considered evidence of the existence of dark matter. An international team of researchers has now analyzed new data and current images from the James Webb Space Telescope (JWST). […]

Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few seconds than the sun emits in 10 billion years. Los Alamos National Laboratory scientists, having […]

A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star’s detonation sent its binary companion hurtling […]
