JUICE and the Hubble Space Telescope turned their gazes towards the interstellar visitor in November.

New simulations suggest TRAPPIST-1e's possible methane atmosphere may be a false signal from its star, raising fresh questions about the planet’s habitability.

NASA imaged Comet C/2025 R2 (SWAN) every four minutes for nearly 40 days, marking the longest any comet has been tracked with such frequency.

A new joint analysis from the NOvA and T2K experiments offers the most precise look yet at neutrino behavior, bringing scientists closer to understanding why the universe is made of matter.

Asteroid Bennu samples contain life-friendly sugars, a strange "space-gum," and ancient stardust

"This is a snapshot of where we are very early in the scientific process."

A new set of computer simulations may finally explain several long-standing mysteries surrounding gigantic radio "relics" that appear when galaxy clusters collide.

"All that remained was the particular flat shape."

Parts of Earth's magnetic field work in reverse compared to what long-standing models predict, new research suggests.

A European Mars orbiter spotted barcode-like dust streaks on the slopes of Apollinaris Mons, revealing how tiny avalanches help drive the Red Planet's massive dust cycle.

New lab experiments suggest that water may not be a rare visitor delivered by chance but rather a fundamental ingredient woven into the process of planetary birth.

"Solar Orbiter can now provide this missing piece of the puzzle."

NASA's first dual-satellite mission to another planet, ESCAPADE, will study Mars' magnetic field and atmosphere in 3D to uncover how it lost its water and air.

"This discovery ends a protracted search for these waves that has its origins in the 1940s."

Two new climate reports warn Earth's vital signs are flashing red after the hottest year in 125,000 years, but say recovery is still possible with swift action.

New research shows how Jupiter carved out rings and gaps that changed how and when planets and meteorites formed.

The century-old mystery of dark matter — the invisible glue thought to hold galaxies together — just got a modern clue.

Ancient rocks from Greenland, Canada and Hawaii preserve a rare chemical fingerprint that may come from the Earth before the moon-forming impact, a new study reports.

A new study suggests dark matter could subtly tint or polarize light, leaving faint color clues that next-generation telescopes might detect.

From how space rocks wobble to where to hit them, scientists are learning the fine art of asteroid deflection — and it could one day save Earth.

After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287.

Scientists have spotted the first clear sign of water from an interstellar comet, 3I/ATLAS, offering new clues to the chemistry of other planetary systems.

Two decades of spacecraft images reveal more than 1,000 dust devils whipping across Mars at unexpected speeds, offering fresh insight into how wind and dust shape the Red Planet.

Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a decades-old mystery about why such stars rarely appear to go supernova.

NASA's Perseverance rover has found minerals that could have powered life on Mars — or simply shaped the Red Planet's environment in fascinating ways.
