Innovative approaches advance search for ice on the moon

14 hours 19 min ago
Scientists and space explorers have been on the hunt to determine where and how much ice is present on the Moon. Water ice would be an important resource at a future lunar base, as it could be used to support humans or be broken down to hydrogen and oxygen, key components of rocket fuel. Researchers are now using two innovative approaches to advance the search for ice on the Moon.

Astronomers discover a planet that's rapidly disintegrating, producing a comet-like tail

Tue, 04/22/2025 - 10:13am
A planet 140 light-years from Earth is rapidly coming apart due to its close proximity to its star. The roasting planet is effectively evaporating away: It sheds an enormous amount of surface minerals as it whizzes around its star.

Did it rain or snow on ancient Mars? New study suggests it did

Mon, 04/21/2025 - 1:31pm
Geologists weigh in on a long-running debate about Mars: Billions of years ago, was the Red Planet warm and wet or cold and dry?

Scientists probe the mystery of Titan's missing deltas

Fri, 04/18/2025 - 10:37am
New research finds that despite large rivers and seas of liquid methane, Saturn's moon Titan seems mostly devoid of river deltas, raising new questions about the surface dynamics on this alien world.

Strongest hints yet of biological activity outside the solar system

Wed, 04/16/2025 - 5:40pm
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

Ever wonder why some meteor showers are so unpredictable?

Wed, 04/16/2025 - 12:21pm
Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.

Cosmic twist: The universe could be spinning

Wed, 04/16/2025 - 12:21pm
A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest puzzles.

'Big surprise': Astronomers find planet in perpendicular orbit around pair of stars

Wed, 04/16/2025 - 12:19pm
Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a stellar pair.

Crystal clues on Mars point to watery and possibly life-supporting past

Wed, 04/16/2025 - 12:19pm
A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring scientists one step closer to answering the profound question: Did life ever exist on Mars?

Scientists find evidence that overturns theories of the origin of water on Earth

Wed, 04/16/2025 - 10:59am
Researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early Earth to understand the origin of hydrogen on our planet. The research team demonstrated that the material which built our planet was far richer in hydrogen than previously thought. The findings support the theory that the formation of habitable conditions on Earth did not rely on asteroids hitting the Earth.

The most distant twin of the Milky Way ever observed

Wed, 04/16/2025 - 10:57am
An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang and already shows a remarkably mature structure, with a central old bulge, a large star-forming disk, and well-defined spiral arms. The discovery was made using data from the James Webb Space Telescope (JWST) and offers important insights into how galaxies can form and evolve so rapidly in the early Universe.

On Jupiter, it's mushballs all the way down

Tue, 04/15/2025 - 3:34pm
Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real process associated with fierce lightning storms: strong updrafts generate slushy, ice-coated hailstones of ammonia and water that eventually plunge into the planet and deplete areas of ammonia. This is part of the first 3D picture of the planet's atmosphere, which shows storms are primarily shallow.

AI finds new ways to observe the most extreme events in the universe

Tue, 04/15/2025 - 11:38am
Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To observe them, ultra-precise detectors are required. Designing them remains a major scientific challenge for humans. Researchers have been working on how an artificial intelligence system could explore an unimaginably vast space of possible designs to find entirely new solutions.

Molten Martian core could explain red planet's magnetic quirks

Tue, 04/15/2025 - 11:35am
First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its imprint is strongest in the southern hemisphere. Researchers found that Mars could have produced a one-sided magnetic field with a fully molten core, rather than the traditional, Earth-like solid inner core setup.

Mysterious atmosphere of 'Rosetta Stone' exoplanet

Tue, 04/15/2025 - 11:34am
A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is only 73 light years from Earth and could serve as a 'Rosetta Stone' for understanding an entire class of new planets.

Scientists may have solved a puzzling space rock mystery

Mon, 04/14/2025 - 9:47am
Researchers may have answered one of space science's long-running questions -- and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than 5 per cent of meteorites found on Earth.
