Earthquakes may make their presence known through GPS measurements several hours before their main events.

Asteroid Day is an annual celebration of asteroid science, and a reminder of how important it is to study these potentially dangerous objects. Here's how you can celebrate this year.

The exploration community is still reeling from the announcement that the submersible Titan broke apart, resulting in the death of its five passengers.

May 24 marked the start of Observation Run 4, the latest gravitational-wave hunting effort of the LIGO-Virgo-KAGRA Collaboration. But only LIGO is fully operational at the moment.

Amazon has revealed three terminals that customers might use to link up with Project Kuiper, the company's planned satellite internet program.

Aurora hunters claim that, to look to the night sky in search of these beautiful displays, the dates around the equinoxes are the best.

Asteroid Launcher, a new web app that gives asteroid impact fanatics a shot at answering some of their questions on what an asteroid crash would be like.

The growing weaponization of space poses a threat to human spaceflight in multiple ways, experts warn.

Thanks to 26 teams of observers, spotting a star blink out showed that asteroid Polymele has a moon.

The moon's surface is pockmarked with hundreds of little pits, each about the size of a large building, and it may not be just the pits' size that would feel familiar to an astronaut.

If nuclear-powered spaceflight is ever realized, there will be a need for new types of robots to perform dangerous maintenance tasks.

Thousands of distant galaxies in different shapes and sizes glow in infrared light in a newly released image from the Hubble Space Telescope.

NASA's Lucy mission has gained a new destination: a tiny asteroid that's orbiting one of its original target asteroids.

Astronomers found a binary star system that may have formed when a wandering star fell into the gravity of its partner.

This weekend, Earthlings might be treated to the sight of a new meteor shower. Astronomers certainly hope it happens.

Volcanoes erupting on the moon billions of years ago may have created a layer of ice under the lunar surface, a new study suggests.

It's no coincidence that the headlines have been full of solar flares and storms: Solar cycle 25, as astronomers call it, is now well under way.

A ridge etched into the ice sheet of Greenland provides an unexpected hint that plentiful pockets of water may be trapped just underneath the surface of Jupiter's ice-covered moon Europa.

Telescopes that observe the universe in the most energetic form of light may help scientists detect the "fingerprints" of gravitational waves, new research reveals.

Finding alien worlds in distant solar systems is a delicate task.

Since astronomers began finding exoplanets in the 1990s, they've uncovered a lot of hot Jupiters, and now NASA's most venerable telescope is playing meteorologist.

Around the world, astrophysicists are poring over the blips of gravitational waves that ripple through Earth when distant black holes or neutron stars collide. Most don't also attend high school.

The Milky Way's thick disk is 2 billion years older than astronomers previously thought and likely formed barely 800 million years after the Big Bang.
