A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
A recent preprint paper examines the minimum number of people required to maintain a feasible settlement on Mars while accounting for psychological and behavioral factors, specifically in emergency situations. This study was conducted by a team of data scientists from George Mason University and holds the potential to help...
We once thought the Moon was completely airless, but it turns out it has an atmosphere, after all. Even wilder: it has a tail of its own.
The first world that humans should inhabit beyond the Earth is the Moon, not Mars. Here's how to terraform our lunar neighbor.
The Psyche asteroid, a celestial object laden with precious metals and valued at an astounding $10,000 quadrillion.
NASA's first asteroid samples fetched from deep space parachuted into the Utah desert Sunday to cap a seven-year journey.
OSIRIS-REx's samples of asteroid Bennu will land at 10:42 a.m. EDT (1442 GMT), while the spacecraft itself heads to a new target.
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard.
You come at the king, you best not miss.
On October 14, 2023, the Americas will experience a partial solar eclipse, but from only eight U.S. states will it be possible to see the 'ring of fire' annular solar eclipse.
A University of Kansas survey of a swath of the cosmos using the James Webb Space Telescope has revealed active galactic nuclei (AGN)—supermassive black holes that are rapidly increasing in size—are rarer than many astronomers had assumed previously.
Microgravity research and technology development on the ISS will continue "full throttle" through the end of 2030, the agency says.
'We now have for the first time vestiges of times that could have been conducive to the origin of life.'
The James Webb Space Telescope detected water vapor swirling around a planetary system 370 light-years away.
Modern solar panels can harness not just ultraviolet light, but also visible and in some cases infrared. But all of these designs are built to harness the sun, which gives off most of its light in the green range and emits plenty of ultraviolet light. But most exoplanets orbit red dwarf stars, which have a peak brightness in the...
Three comets named Hartley, Encke and Tsuchinshan will pass by the sun in the next few months and be visible from Earth. Here’s how you can spot them
Region at centre of Messier 87 galaxy captured by the Event Horizon Telescope in motion
The sun’s outer atmosphere is vastly hotter than its surface. Scientists may be close to figuring out why.
NASA's quest for extraterrestrial life now includes technosignatures, evidence of advanced civilizations on distant exoplanets. Through AI, new research methods, and a broadened focus, scientists remain hopeful in discovering life beyond Earth. Our first confirmed proof of life beyond Earth might
The decade-long concerns continue. NASA needs to be more transparent about the costs and schedules associated with its Space Launch System (SLS) moon rocket, a newly released audit has found.
India's space agency Isro's new footage shows Chandrayaan-3's rover Pragyaan for the first time ever.
Using nuclear fusion, Pulsar's rocket could dramatically increase travel speeds, aiming for tests by 2025 and fusion temperatures by 2027.
Get ready stargazers: The Perseid meteor shower and a super blue moon are highly anticipated sights this August.
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new giant exoplanet transiting a nearby M-dwarf star. The newfound alien world, designated TOI-4860 b, is comparable in size and mass to Saturn. The finding is reported in a paper published August 2 on the pre-print...
