Cosmic archeologists have used the James Webb Space Telescope to excavate ancient disk galaxies that tell the story of how the Milky Way and other modern galaxies evolved.

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black holes or a cosmic particle accelerator.

The Mars rover captured images of low ridges called boxwork patterns, which appear like spiderwebs from space.

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

"Its occurrence is like finding a tropical seed in Arctic ice – indicating either an unexpected local environment or long-distance transport in the early solar system."

Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.

"Each new detection brings us closer to understanding the origins of complex organic chemistry in the universe — and perhaps, the origins of the building blocks of life themselves."

The satellites were seen in the night skies near the summit of Mauna Kea in Hawaii.

With the aid of NASA's exoplanet-hunter TESS, citizen scientists have discovered a new gas giant that is cool, literally and figuratively.
