High-temperature experiments conducted on Earth with lunar rock samples may have finally revealed how a unique type of rock was created and distributed on the moon.

The Hubble Space Telescope zoomed into a galaxy 150 million light years away to study a supernova that released 2.5 billion times more energy than the sun, resulting in a stunning image.

Giant clouds of cold gas in NGC 4945, were blasted through the spiral galaxy when its central black hole erupted 5 million years ago.

Scientists studied 1,500 supernovas to better understand dark energy and the results call the standard model of cosmology into question.

The nearly new moon is set for a close approach to the gas giant Saturn on Sunday, Jan. 14, at which time the two celestial bodies will also be in conjunction.

An unexpected and unexplained gamma-ray signal from beyond the Milky Way found among 13 years of NASA Fermi Telescope data could be linked to another cosmic mystery.

The surface of Venus is a hellscape with temperatures hot enough to melt lead, but some regions of its atmosphere high over the surface remain cool enough to harbor ice and birth ghostly clouds

The James Webb Space Telescope has caught the young planetary system Beta Pictoris by the tail seeing a new structure of dust that resembles the lower half of a cat.

NASA's exoplanet-hunting TESS spacecraft has discovered an Earth-sized alien world called HD 63433 d that is surprisingly young and has a hemisphere of scorching-hot lava.

Astronomers inadvertently discovered a "dark" galaxy rich in gas but lacking stars when they pointed the Green Bank Telescope in the wrong direction.

The elusive planet Mercury reaches its furthest point from the sun on Friday (Jan. 12), with this separation allowing skywatchers a rare chance to spot the tiny planet.

Astronomers have discovered a "missing link" supernova that directly connects the death of a massive star to the birth of a black hole or a neutron star.

On Jan. 9, China launched its Einstein Probe to observe the X-ray sky, hunting for high-energy light from neutron stars, feeding black holes and other exotic objects.

Mysterious "odd radio circles" or ORCs that compass entire galaxies may have finally been explained, with astronomers pointing the finger at winds from bursts of supernova star explosions.

The James Webb Space Telescope has spotted signs of a ghostly aurora over a 'failed star,' in the form of infrared emissions from methane in the brown dwarf's atmosphere.

Astrobotic's Peregrine Lander has set the stage for a new era of commercial missions to the moon in the coming years.

Astrobotic's Peregrine moon lander launched today (Jan. 8) with five NASA science payloads aboard. Here's what the experiments are designed to do.

On Saturn's largest moon, Titan, snows of organic compounds may form glacier-like honeycomb chunks in methane lakes, appearing as floating "magic islands."

New observations of the Small Magellanic Cloud show that it might actually be two galaxies disguised as one.

Satellite images show major cities on the U.S. East Coast, including New York City, are sinking. This has caused concern among scientists.

The mystery of what dwells within dead stars could be solved at last, thanks to supercomputer simulations that show neutron stars are comprised of "cold quark matter."

If the James Webb Space Telescope detects depleted carbon dioxide in a planet's atmosphere, that could indicate water.

On Dec. 30, 2023, NASA's Juno spacecraft came closer to the volcanic moon Io than any other mission has in 20 years. In the process, Juno was able to grab some incredible images.

A coronal mass ejection from an X-5 class flare that erupted on New Year's Eve, the strongest flare of solar cycle 25, will likely trigger geomagnetic storms when it hits Earth today (Jan. 2).

Astronomers have discovered a new gas cloud created by winds blown from a rapidly spinning neutron star, naming it "Potoroo" after a small Australian marsupial.
