New evidence that Mars was volcanically active around 4 billion years ago could provide researchers with more places to hunt for signs of ancient life on the Red Planet.

Our universe's lack of super-Earths or mini-Neptunes could be caused by some planets migrating toward the hearts of their systems early on in their lives.

A young star's extreme outburst could show us the violent conditions that may be experienced by planets, including those of the solar system, as they form in infant systems.

Using the James Webb Space Telescope astronomers have zoomed in on a dwarf galaxy in the Milky Way's local group to understand the ebb and flow of star formation since the early universe.

The Vera C. Rubin Observatory won't ever leave Earth, but its big picture, highly detailed view of the solar system will inspire a new era of space missions destined to visit asteroids.

Observations of bright galaxies in the early universe could indicate that black holes were driving star formation and galaxy growth just 50 million years after the Big Bang.

NASA's Juno spacecraft has seen Jupiter's volcanic moon Io like never before, catching active eruptions, lava flows, and a side to the solar system's most volcanic body not seen in 35 years.

CERN has revealed further plans for the Future Circular Collider, which will dwarf the Large Hadron Collider in size and power to hunt for dark energy and dark matter.

The upcoming solar maximum may help scientists solve the puzzle of why the sun's poles emitted ten times more high-energy radiation than expected during the last peak in activity.

Infant exoplanets may not be spherical as astronomers have always assumed. Instead, they may be oblate spheroids, like the 'Smarties' candy found in Europe.

Astronomers have made a shock discovery that Saturn's moon Mimas seems to have a liquid ocean beneath its surface, potentially redefining our search for life on alien moons.

Do the Milky Way's most common planets, mini-Neptunes, have atmospheres filled with opaque clouds or a more transparent haze?

Thanks to a powerful engine burn on Feb. 3, NASA's asteroid-hopping Lucy spacecraft is on its way back to Earth for a Christmas-time rendezvous this year.

Over the course of 3 years, Chandrayaan-2 observed thousands of mysterious, slow-building, ultra-hot solar flares as they erupted from the sun.

When asteroid 2024 BX1 exploded over Earth it littered the planet with rare meteorites that are similar in composition to the unspoiled building blocks of our planet.

NASA's exoplanet-hunting spacecraft TESS has spotted a 'super-Earth' in the habitable zone of its red dwarf star, with indications it may have Earth-sized company.

The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.

Space Mysteries High-energy particles from space constantly bombard Earth at near light speed, but what are their origins?

NASA experts spoke ahead of the launch of the ocean and atmosphere studying spacecraft PACE from Cape Canaveral Space Force Station early on Feb. 8.

The ALMA telescope spotted a molecular gas outflow coming from a black hole-powered, 13-billion-year-old quasar, explaining why some galaxies stop forming stars.

NASA's Hubble Space Telescope has observed a cosmic 'tug of war' between two galaxies that have lasted for tens of millions of years and could end in a collision.

A nearby supermassive black hole is erupting, and astronomers spotted the outburst using the Event Horizon Telescope.

The James Webb Space Telescope has directly imaged two exoplanets orbiting white dwarf stars. These systems offer a glimpse at the future of our solar system after the sun has died.

The XMM Newton space telescope has seen a feeding supermassive black hole as it throws a major tantrum, "flipping over the table" and preventing its parent galaxy from birthing new stars.
