Watch a NASA moon rover complete a lunar obstacle course (video)
A prototype of the lunar rover demonstrated its capabilities in navigating the moon's challenging terrain.
NASA satellite captures Sahara Desert dust plume over the Atlantic Ocean
NASA's Aqua satellite photographed plumes of dust being drawn from Africa's Sahara Desert and sent across the Atlantic towards the United States and the Caribbean.
Hubble Space Telescope captures photo of a dazzling star cluster
The Hubble Space Telescope has imaged globular cluster NGC 6638, located in the constellation Sagittarius.
The Curiosity rover has been exploring Mars for 10 years. Here's what we've learned.
Curiosity landed on Mars on Aug. 5, 2012, with one main goal: to determine whether the planet was once habitable. In 10 years, it has answered that question and many others.
Perseverance Mars rover photographs its own landing debris
As the Mars rover traverses the planet, it's come across pieces of its entry, landing, and descent hardware.
New clues emerge about runaway star Zeta Ophiuchi's violent past
The runaway star is dashing across the galaxy at more than 100,000 mph, thanks to a massive explosion that happened more than a million years ago.
Could we eavesdrop on aliens by detecting signals relayed around the sun?
Researchers suggest we may be able to use gravitational lensing to amplify radio waves, allowing us to listen in on communication signals passing through our solar system.
This monster black hole is spinning much more slowly than others. Scientists want to know why.
Scientists have measured how fast a supermassive black hole is spinning, and the result might give us a clue about how the giant formed.
A NASA telescope aboard a high-altitude balloon will float over the South Pole to study a 'star-killer'
The Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths (ASTHROS) will study an unusual "star-killer" phenomenon.
Moon rock trait offers new way to understand impact history
The moon is covered by impact craters large and small, evidence of a violent history of bombardment by celestial bodies like comets and asteroids. But these craters only record some of lunar history.
James Webb Space Telescope will get best view yet of 'failed stars' and rogue planets
One of the instrument's early programs includes performing spectroscopy on stellar nursery NGC 133 to spot the small, dark celestial bodies.
James Webb Space Telescope has comets to catch when science begins
The James Webb Space Telescope's powerful infrared instruments will be trained on three types of comets, potentially providing insight into the solar system's early life.
NASA's flying SOFIA observatory is in New Zealand for the last time
For its last international deployment, the aircraft returns to Christchurch for a seventh and final time.
NASA's Europa Clipper may crash into Ganymede, the largest moon in the solar system, at mission's end
The Europa Clipper mission, due to launch in 2024, was originally supposed to crash into Jupiter, but there's been a change of plans.
'Emerging super Crab' might be the most powerful pulsar ever discovered
Sifting through data from the Very Large Array Sky Survey, scientists have observed an object that might be a "pulsar wind nebula."
World's largest liquid mirror telescope ready to observe
The 4-meter-wide International Liquid Mirror Telescope (ILMT) at Devasthal Observatory in the central Himalayas comes online.
Newly spotted asteroid near Venus earns name from Pauma band of Native Americans
Scientists at the Palomar Observatory turned to the Pauma band, upon whose ancestral lands the facility sits, to name the asteroid, now dubbed 'Ayló'chaxnim, or 'Venus girl.'
Wobbly jets of binary star systems may affect chances of hosting life
Because Earth is the only planet known to host life as we know it, researchers have usually focused on planetary systems similar to our own when searching for extraterrestrial life.
Ultracold gas bubbles on the space station could reveal strange new quantum physics
The test was designed to study how gas behaves in microgravity, and the results may lead to future experiments with the fifth state of matter, Bose-Einstein condensates.
NASA's Perseverance Mars rover hears an alien soundscape that changes with the seasons
A year's worth of sound recordings from NASA's Perseverance rover reveals that it's very quiet on Mars.
Rocket exhaust pollution in the upper atmosphere might affect Earth's climate
A new study reveals how air pollution from rocket launches spreads in Earth's atmosphere.
This tiny space rock might be the 1st physical evidence of a rare supernova
Scientists who analyzed the chemical composition of a space rock called the Hypatia stone suspect they have discovered evidence of a rare type of supernova.
Scientists witness a white dwarf's massive X-ray explosion for the 1st time ever
European scientists used the eROSITA X-ray telescope to observe a white dwarf nova for the first time.
