Landsat satellites have been pinpointing risks of extreme heat within cities.

Sunspots are typically no real reason to worry, even if they double in size overnight and grow to twice the size of the Earth itself. That’s just what happened with Active Region 3038 (AR3038), a sunspot that happens t...

Alien rocky worlds cocooned in hydrogen and helium could prove habitable to life as we know it for billions of years, with key features such as temperate conditions and liquid water, a new study finds.

Neptune will enter retrograde on Tuesday (June 28) and will appear to 'reverse its course' as it moves across the sky. Here's how to see it.

We should be intrigued, but not too excited (yet). Any interesting signal has to go through a lot of tests to check whether it truly carries the signature of extraterrestrial technology.

The Large Hadron Collider is the world's biggest particle accelerator. It's located at the European particle physics laboratory CERN, near Geneva, Switzerland.

Video: 00:01:06 A beautiful sequence of 56 images taken by the monitoring cameras on board the ESA/JAXA BepiColombo mission as the spacecraft made its second close flyby of its destination planet Mercury on 23 June 2022....

The two companies NASA selected earlier this month to develop spacesuits for the International Space Station and Artemis lunar missions were the only companies to bid on the project, according to agency procurement docum...

The Lunar Reconnaissance Orbiter (LRO) - NASA's eye-in-the-sky in orbit around the Moon - has found the crash site of the mystery rocket booster that slammed into the far side of the Moon back on March 4th, 2022. The LRO...

In the American Wild West, high noon was a time for duels and showdowns. When it comes to the history of the universe, cosmic noon featured fireworks of a different sort. Some 2 to 3 billion years after the big bang most...

Scientists using data from NASA's Curiosity rover measured the total organic carbon - a key component in the molecules of life - in Martian rocks for the first time....

According to a new NASA laboratory experiment, rovers may have to dig about 6.6 feet (two meters) or more under the Martian surface to find signs of ancient life because ionizing radiation from space degrades small molec...

A new study has shown how gravitational waves can be used to detect exotic particles orbiting black holes. The post We Could Discover new Kinds of Particles Around Black Holes Through Gravitational Waves appeared first o...

Northop Grumman's robotic Cygnus freighter is scheduled to undock from the orbiting lab at 6:05 a.m. EDT (1005) Tuesday. Watch it live here at Space.com, courtesy of NASA.

One of the James Webb Space Telescope's four primary scientific instruments, known as the Near-Infrared Imager and Slitless Spectrograph instrument (NIRISS) has concluded its post-launch preparations and is now ready for...

An exoplanet hunter and first-light detector on the James Webb Space Telescope is ready to do science, six months after the observatory launched to space.

A new video shows the crater-riddled surface of the solar system's smallest planet Mercury as captured during a super close flyby of the BepiColombo spacecraft.

Asteroid research and planetary defense is of great interest to scientists around the world, which is why June 30 marks international Asteroid Day.

House appropriators partially restored funding for a planetary defense mission as part of a spending bill while also raising concerns about NASA's closure of an airborne observatory and plans to return samples from Mars....

Life on Earth began in the oceans. In the search for life on other planets, the potential for liquid water is therefore a key ingredient. To find it, scientists have traditionally looked for planets similar to our own. Y...

Despite several high profile missions to find an Earth-like planet orbiting a Sun-like star, astronomers have failed to find one. Now the Chinese are launching their own space telescope to hunt for Earth 2.0.

Northrop Grumman's uncrewed Cygnus spacecraft is scheduled to depart the International Space Station on Tuesday, June 28, more than four months after delivering 8,300 pounds of supplies, scientific investigations, commer...
