The James Webb Space Telescope has spied a distant galaxy that represents the wreckage of a titanic collision between two galaxies 500 million years ago.
ODIN Space's demonstration team confirmed their new debris sensor successfully recorded acoustic data during its recent on-orbit test, bringing micro-space debris tracking a step closer to reality.
New observations of the sun have revealed never-before-seen meteor-like fireballs raining down as shooting stars on the surface of the sun.
After a year without people, the sky would be bluer, the air clearer. The wind and the rain would scrub clean the surface of the Earth; all the smog and dust that humans make would be gone.
The Hubble Space Telescope has spied on the Milky Way's galactic neighbor, irregular galaxy ESO 174-1, imaging it as a lonely hazy cloud.
A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas.
Stunning first videos from a new space-borne instrument designed to improve the monitoring of thunderstorms show the crackle of lightning over Europe, Africa and the Atlantic Ocean.
Astronomers have discovered high amounts of tryptophan, an amino acid key in the formation of life, in a nearby star-forming region of space called the Perseus Molecular Complex.
The giant sunspot AR3354 blasted out an X-class solar flare on Sunday, July 2, ionizing Earth's atmosphere and causing a shortwave radio blackout over the U.S. and the Pacific Ocean.
The sun has produced 163 sunspots in June, the highest monthly number in more than two decades, sparking concerns that Earth may soon face space weather trouble.
The Royal Observatory of Greenwich released a shortlist of the top submissions for 2023 Astronomy Photo of the Year. and the pictures are incredible.
The very fabric of the universe is ringing with gravitational waves from its earliest epoch, and researchers have finally "heard" this cosmic symphony.
Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.
The European-led Euclid mission will launch July 1 aboard a SpaceX Falcon 9 rocket. Here's how to watch the free webcast of the liftoff.
Dark matter and dark energy distort traditional Euclidean geometry in the universe, and the Euclid mission will measure how much they distort it by.
We have never seen dark matter and dark energy, so why do we think they exist? And what would happen if Europe's new space telescope Euclid finds evidence that they don't exist after all?
The Euclid spacecraft, which aims to shed light on dark matter and dark energy, is ready to lift off atop a SpaceX Falcon 9 rocket on Saturday (July 1).
Saturn's famous rings shine bright in an incredible new photo by NASA's James Webb Space Telescope, its first officially released shot of the gas giant.
