Asteroid-Deflecting Missions May Need to Hit Asteroids in the Perfect Spots to Prevent Future Collisions

NASA’s DART mission proved we are able to change an asteroid’s path by smashing a spacecraft into it, but exactly where we hit a rocky body is important

The Perseverance rover sampled Cheyava Falls, a rock with "leopard spots," on Mars last year.

NASA Discovers ‘Clearest Sign’ Yet of Ancient Life on Mars in a Rock Studied by the Perseverance Rover

Minerals in the rock might have been produced by microbes in chemical reactions, but researchers say they’ll need to examine the sample more closely to know for sure

The dwarf planet Ceres, the only dwarf planet in the main asteroid belt, might have once been hospitable for life, according to a recent study.

Did the Dwarf Planet Ceres Once Host Life? Astronomers Suggest Chemical Energy Could Have Fueled Microbes Long Ago

Though no direct evidence of life has been found, models suggest Ceres had hot water shooting into its underground oceans billions of years ago, offering potentially hospitable conditions

This year, a nearly full moon will make observing the Perseids harder. Here, a meteor is seen on August 3, 2025, in Spruce Knob, West Virginia.

The Popular Perseid Meteor Shower Will Peak This Week—Here’s How to Watch, Despite a Bright Moon

A waning gibbous moon will impact viewing the shooting stars, but the famous meteor shower is still worth observing

Jim Lovell while training for the Apollo 13 mission

Jim Lovell, Apollo 13 Commander Who Thrived Under Pressure, Dies at 97

The space explorer was determined throughout his life, says Teasel Muir-Harmony, the curator of the Apollo Collection at the National Air and Space Museum

Christa McAuliffe’s Life Ended in Tragedy on the ‘Challenger’ Shuttle. Here’s How the High School Teacher Was Chosen for the Ill-Fated Flight

NASA’s “Teacher in Space” added joy to many Americans’ lives and increased excitement for the future of spaceflight, though she never reached her destination

A NASA astronaut captured this odd weather phenomenon, called a red sprite, from the International Space Station.

Mysterious ‘Red Sprite’ Appears in NASA Astronaut Photo From the Space Station. What Is This Strange Electrical Flare?

Red sprites are among a class of enigmatic weather phenomena that appear over thunderstorms, known as Transient Luminous Events

An illustration shows a satellite damaged by space debris. Objects that don’t burn up in the atmosphere can pose a danger when they fall back to Earth.

With Space Junk on the Rise, Is a Catastrophic Event Inevitable?

Debris from rockets and satellites can fall back to Earth or collide with other objects, and wreckage that burns up can harm the ozone layer

NASA's ANITA experiment is lifted above Antarctica by a balloon and seeks to detect radio pulses connected to neutrinos.

Mysterious Radio Pulses Found in Antarctica Seem to Defy Physics, and Researchers Are Trying to Trace Their Origins

Strange signals detected by a NASA instrument more than a decade ago have continued to confound scientists, but a new paper rules out cosmic neutrinos as a source

The Solar Orbiter has captured the first-ever views of the sun's south pole.
