A Soviet Spacecraft Is About to Crash Back to Earth After Being Stuck in Orbit for 53 Years

The Cosmos 482 lander was intended to reach Venus, but it has instead been circling Earth since 1972

An artistic rendering of an exoplanet in a tight orbit, followed by a dusty, comet-like tail of debris.

Astronomers Discover a Doomed Exoplanet That’s Crumbling Away and Leaving Behind a Comet-Like Tail

The planet orbits its host star in just 30.5 hours, losing a mass of material roughly equal to Mount Everest each time

The commemorative watch was given to Armstrong at a gala dinner in Houston in November 1969.

A Gold Watch That Belonged to Astronaut Neil Armstrong Sold for $2.1 Million at Auction

The commemorative timepiece is similar to the one that Armstrong and other NASA astronauts wore in space

The asteroid Donaldjohanson, captured by NASA's Lucy spacecraft on Sunday. 

NASA’s Lucy Spacecraft Just Flew by a Strange, Peanut-Shaped Asteroid. See the New Images From the Approach

The close-up views of asteroid Donaldjohanson are a preview of what’s to come for Lucy on its 12-year quest to study Jupiter’s Trojan asteroids

A reconstruction of a Neanderthal man in the Natural History Museum, Vienna. A new study suggests Neanderthals could not adapt to a period of increased radiation as well as early modern humans did.

Sunscreen, Clothing and Caves May Have Given Modern Humans an Edge Over Neanderthals When Earth’s Magnetic Field Wandered

A new study suggests the extinction of Neanderthals nearly coincided with a shift in Earth’s magnetic field that let more radiation reach the ground. Our species might have adapted more easily

The Lyrid meteor shower coincided with a nearly full moon at its peak in 2024, seen here at Joshua Tree National Park. This year, conditions will be more favorable.

How to Watch the Lyrid Meteor Shower at Its Dazzling Peak

The annual spectacle, which is happening now, will last until around April 25—but the best viewing will fall between the 21 and 22

A rendering of a Sunbird rocket detaching from its station to dock onto an approaching spacecraft.

Fusion Rockets Could Theoretically Cut Our Travel Time to Mars in Half. This U.K. Startup Wants to Give It a Try

The company’s ambitious new Sunbird design aims to harness nuclear fusion in space, despite the fact that commercializing such energy on Earth remains a faraway dream

An artist's impression of K2-18b and its distant host star, visualized as if the planet had water and a hydrogen-rich atmosphere.

Chemical Hints on a Distant Planet Offer ‘Strongest Evidence Yet’ for Life Outside Our Solar System, Astronomers Say

The James Webb Space Telescope spotted possible signatures for life in an exoplanet’s atmosphere. Still, researchers caution it’s far too early to call the findings definitive

The far side of the moon—seen here, captured by NASA's Lunar Reconnaissance Orbiter—could be much drier than expected.

The Moon’s Far Side Is Strangely Dry—Lunar Samples Suggest It’s Much More Parched Than the Side That Faces Earth

Chinese researchers analyzed the first-ever soil samples returned from the far side of the moon, but further samples will be needed to verify their findings

Comet C/2025 F2 (SWAN) captured from California. 

A Newly Discovered and Brilliantly Green Comet Is Dazzling Astronomers. Here’s What to Know About the Glowing Celestial Visitor

Initial observations suggest the comet, called C/2025 F2 (SWAN), will continue getting brighter as it approaches the sun. Northern Hemisphere viewers with binoculars can currently spot it in early morning skies

Biomass will monitor the Earth's tropical forests over the next five years.

A New Satellite Will Map the Carbon Content of Rainforests From Space, and It’s Set to Launch This Month

The European Space Agency’s new probe, Biomass, will spend five years orbiting the planet and gathering radar imagery of forests across multiple continents

An artistic rendering of the moment when the first white dwarf explodes and spews material at the second white dwarf, which itself is about to explode. 

Astronomers Discover a Rare White Dwarf Pair Doomed to Explode in a Brilliant Supernova

The event will be ten times brighter than our Moon in the night sky, but never fear, it won’t happen for another 23 billion years

NASA’s Perseverance Mars rover spotted a large dust devil (on the right) consuming a smaller, fainter twister (on the left in the foreground).

Watch a Spinning Martian Dust Devil ‘Consume’ Another in a New Video Captured by NASA’s Perseverance Rover

Tracking dust devils helps researchers learn more about Mars’ atmosphere, wind and weather conditions

The Fram2 mission captured this view of polar ice from orbit.

Four Civilian Astronauts Capture Imagery of Earth’s Icy Poles on Fram2, the First Crewed Mission to Polar Orbit

The mission, funded and commanded by a cryptocurrency entrepreneur, was launched by SpaceX on Monday and has grabbed headlines for its flight path

An artist’s impression of ten hot planets similar to Jupiter outside our solar system that scientists have detected. Creative liberties were taken for the colors of the planets, which are currently unknown. The exception is the top-right one, which is known to sport a blue exterior.

From Worlds That Look Like Cotton Candy to Others Covered in Volcanoes, These Are the Strangest and Most Captivating Exoplanets

Scientists are using an array of instruments to detect other planets, some of which may harbor life—and others that most definitely don’t

Spectrum launched from the Andøya Space Center in Norway before plumetting into the icy sea.

First Orbital Rocket Launched From Western Europe Crashes Into Sea After Roughly 30-Second Flight

Isar Aerospace, the company behind the rocket, is still heralding the launch as a success due to the data it provided

For the first time, the "Mission MushVroom" experiment on SpaceX's Fram2 mission will attempt to grow mushrooms in space.

SpaceX Astronauts Will Try Growing the First Mushrooms in Space on Upcoming Fram2 Mission Over Earth’s Poles

Described as the “perfect space crop,” the nutritious and ready-to-eat fungus could be a key stepping stone toward fueling crew members during long-term spaceflight

A partial solar eclipse on June 10, 2021, rises at Lewes Beach in Delaware.

How to Watch a Live Stream of the Rare Sunrise Eclipse on Saturday and Catch a Glimpse of Solar ‘Devil Horns’

Early risers can observe a partial solar eclipse in areas of eastern North America on March 29, given clear skies and proper eye protection

At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope. At the right, that image is combined with data from NASA’s James Webb Space Telescope to show auroras, represented by cyan coloring.

Check Out Neptune’s Beautiful Auroras, Captured for the First Time by the James Webb Space Telescope

Scientists suspected the ice giant hosted auroras—and had already observed them on Jupiter, Saturn and Uranus. But an observation of Neptune’s lights remained elusive for decades
