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.

PSR J2030+4415's 40-trillion-mile-long beam could explain why scientists see certain strange particles on Earth.

To find features like groundwater under Earth's surface — or under the surface of another world — scientists can sense the subtle marks those features leave in the planet's gravitational field.

Scientists are using quantum computing to understand what's inside a black hole and test if our universe is a holographic projection.

The prototype system, developed by the U.S. National Oceanic and Atmospheric Administration, is designed to alert operators when their spacecraft may be on a collision course with another object.

Neutrinos are so small that scientists once thought they had no mass at all. Neutrinos do have mass, however, and physicists have now put a new upper limit on it: 0.8 electronvolts.

The moon's crust might have formed from an unevenly layered "slush" of magma that once covered the entire body, a new study reports.
