New images from NASA's DART asteroid-smashing mission show space rocks exchanging material in a slow process that reshapes their surfaces over millions of years.

"Life might actually survive being ejected from one planet and moving to another."

Antarctica has lost nearly 5,000 square miles of "grounded ice" in 30 years, as warming ocean waters drive retreat in vulnerable regions, a new study finds.

NASA's Perseverance rover can now pinpoint its exact location on Mars without help from Earth, paving the way for longer, more autonomous exploration.

Scientists may have narrowed down the landing site of the Soviet Union's Luna 9, which in 1966 became the first spacecraft to touch down softly on the moon.

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to how black holes form.

Scientists analyzing decades-old NASA's Magellan data have identified only the second reported lava tube on Venus.

Falling launch costs and private innovation are fueling a new space race, transforming Earth orbit into a fast-growing global marketplace.

"If reproduction is ever to occur beyond Earth, it must do so with a clear commitment to safety, transparency and ethical integrity."

"There is a growing chasm between theory and observation related to the early universe, which presents compelling questions to be explored going forward."

"The fundamental elements of generative AI are showing a lot of promise in streamlining the pillars of autonomous navigation for off-planet driving."

"You need so much water that we think these could be evidence of an ancient warmer and wetter climate where there was rain falling for millions of years."

"We are on Day 1. A lot more needs to be done."

Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes formed without stars.

"A strong magnetic field is very important for life on a planet."

Exhaust from lunar landers drifts across the moon and contaminates ultra-cold polar craters that are rich in ancient ice and organic clues, a new study reports.

"Most excitingly, this new idea addresses one of the longstanding habitability problems on Europa and is a good sign for the prospects of extraterrestrial life in its ocean."

"Instead of Webb's 6.5-meter diameter, it's like we are observing this region with a 13-meter space telescope."

Tiny delays in pulsar signals measured by SETI scientists could aid the search for gravitational waves and extraterrestrial life.

MAVEN was built to last in orbit until 2030 — that's not looking likely anymore.

"It's really not a question of robotic exploration or human exploration," Ehlmann said. "It is an 'and' — it's robotic and human exploration and how we do these best together."

New discoveries and fresh looks at familiar worlds show how far exoplanet science has come — and how much remains unknown.

"There is a lot to keep us busy."

NASA's Parker Solar Probe captured solar material looping back to the sun, revealing how it recycles magnetic energy and shapes future solar storms.

Scientists have created the first detailed maps of the sun's atmospheric boundary, where solar material breaks free and streams into space.
