Two projects using the James Webb Space Telescope will look at the auroras of Uranus and Saturn to discover what processes make them tick.

Recent observations show that some white dwarf stars suddenly stop cooling. Now, scientists propose a 'fountain of youth' mechanism that may explain how these stellar husks avoid death for billions of years.

A stunning new map of the magnetic fields at the Milky Way's center charts never-before-seen features, and raises new questions about how our galaxy's central engine works.

The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.

The beloved James Webb Space Telescope will soon begin working on a fascinating to-do list for 2024 and 2025, including research into black holes, alien moons, dark energy and more.

New observations with the James Webb Space Telescope reveal that dwarf galaxies in the early universe released enough collective radiation to change the cosmos forever.

NASA's DART spacecraft seems to have completely reshaped asteroid Dimorphos after violently crashing into it in Sept. 2022

A neutron star spotted by the James Webb Space Telescope stayed hidden for 37 years while lurking in the wreckage of a stellar explosion, Supernova 1987A.

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another.

The discovery or an ultra-tiny white dwarf could reveal how stars smaller than Jupiter are born.

A meteor that exploded over Germany on Jan. 21 was confirmed to be a rare aubrite, a type of asteroid as old as the solar system.

A new study of Saturn's 'Death Star' moon Mimas finds evidence of a young, underground ocean that may be hospitable to early forms of life.

The James Webb Space Telescope has detected two alien planets orbiting white dwarfs, the collapsed husks of once-mighty stars. The discovery offers a hint of what our solar system will look like after the sun's eventual demise.

Astronomers investigated an active supermassive black hole at the heart of Perseus A using the Event Horizon Telescope, spotting an epic battle between gravity and magnetism.

New simulations show how thousands of galaxies evolve by traveling through the strands of gas, dust and stars that make up the universe's "cosmic web."

Team "pro-exomoon" is back to defend the discovery of the first and only exomoons potentially seen by humanity.

Organic matter found in samples of asteroid Ryugu suggests that ancient comets may be responsible for bringing the 'seeds of life' to Earth.

The powerful James Webb Space Telescope captured a starburst complex in the Large Magellanic Cloud, with stunning results.

The most sensitive image of a globular cluster, a tightly packed ball of ancient stars, has revealed a strange radio signal that could be a black hole.

A new cosmic crime scene reconstruction tells the full story of a star ripped apart by a ravenous black hole, revealing a previously unknown aspect of these tidal disruption events.

The most powerful and distant fast radio burst ever seen has been tracked to a "blob" of galaxies that existed when the universe was less than half its current age.

The Einstein Probe has left Earth to survey the cosmos for X-ray signals from feeding black holes, colliding neutron stars and exploding stars.

Later this year, NASA's Parker Solar Probe will come even closer to the sun than it has before, while traveling at record-breaking speeds.

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.

"Continuous unmitigated subsidence on the U.S. East Coast should cause concern."
