"Even slight downward shifts in land can significantly compromise the structural integrity of buildings, roads, bridges, and railways over time."

A combination of X-ray from NASA's Chandra observatory and radio data indicates that a galactic "fracture" was likely caused by a special neutron star called a pulsar.

The James Webb Space Telescope has observed surface ice methanol — a key building block for organic compounds necessary for life, including sugars — on trans-Neptunian objects.

For the first time, scientists have identified climate change as the top driver of human-caused biodiversity loss among species protected under the Endangered Species Act.

On Easter Sunday (April 20), NASA's Lucy probe should have zipped past the asteroid Donaldjohanson, testing science instruments on the space rock.

Using NASA's Perseverance rover to analyze Martian rocks, researchers suggest that Mars' complex volcanism might hold clues about the planet's ancient habitability.

Hiroyasu Tsukamota has developed a deep-learning-based guidance and control framework called Neural-Rendezvous that could allow spacecraft to safely encounter interstellar objects.

The grand total of Saturnian moons is now 274.

For starters, they taught us that Earth is round

A distant star-killing supernova could have bombarded Earth with radiation strong enough to shift the course of evolution.

After an arduous ascent to the rim of Mars' Jezero Crater, NASA's Perseverance rover is doing a little sightseeing.

Thanks to images from various NASA spacecraft, we can get an up-close look at the Jupiter ocean moon Europa long before the agency's Europa Clipper probe arrives.

The moon has been bombarded by asteroids and comets for more than 4.32 billion years.

On Sept. 30, NASA's Perseverance rover turned its eyes toward the sky and photographed a solar eclipse from Mars, capturing the tiny moon Phobos as it transited the sun.
