New research shows that craters near the moon's south pole that have been in permanent shadow the longest are more likely to contain the most water ice.

SpaceX launched its 1,000th Starlink satellite so far in 2026 with an early morning Falcon 9 rocket launch Tuesday morning from Cape Canaveral Space Force Station.
An ultra-hot Jupiter exoplanet orbiting a young A-type star gave scientists using the Gemini South telescope a look at how both a star and its hot planet can have similar chemical compositions. The team, led by Arizona State University graduate student Jorge Antonio Sanchez, took spectra of the planet, called WASP-189b, using the Immersion Grating Infrared Spectrograph instrument on loan from McDonald Observatory in Texas. The observations measured the abundance of magnesium compared to silicon in the hot planet's atmosphere and allowed the team to compare it to the makeup of its parent star.
Even a modest telescope reveals the breathtaking Saturnian ring system that has captivated astronomers for four centuries, a world so alien in its beauty that first time observers often struggle to believe what they are seeing is real. But Saturn's rings are just the beginning. Beneath that iconic silhouette lies a planet of extraordinary extremes, a gas giant eleven times wider than Earth, spinning so fast that a single day lasts barely ten hours, and wrapped in a magnetic field so powerful it dominates a region of space millions of kilometres in every direction.
We have been searching for signals from other civilisations for over sixty years. Radio telescopes on Earth have swept the sky, listened patiently, and found nothing but silence. It is a search that demands extraordinary sensitivity and that is the problem, Earth and our very existence itself is getting in the way.
Space is full of objects that push the boundaries of imagination, but few do it quite as effectively as a black hole. At its simplest, a black hole is a region of space where gravity has become so overwhelmingly powerful that nothing, no matter, no light, nothing can escape its grip. They form when massive stars reach the end of their lives and collapse catastrophically inward, crushing an enormous amount of mass into an extraordinarily small space. The result is an object so dense that it warps the very fabric of space and time around it.
It just goes on and on, my friends.
"This is the least transparent NASA budget request I've ever seen — and I've literally looked through every single one since 1960."
Black holes are among the most fascinating and extreme objects in the universe. They are regions of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
When India's Chandrayaan-1 orbiter released the Moon Impact Probe (MIP) into the Shackleton crater on the Moon, they confirmed something scientists had speculated about for decades. The Moon, an airless and vacuum-desiccated body, has abundant sources of water ice around its poles! Located in the many craters that litter the region, these permanently shadowed regions (PSRs) prevent this water from being exposed to sunlight, which would cause it to sublimate and be lost into space.
The uncrewed Northrop Grumman Cygnus XL spacecraft, the S.S. Steven R. Nagel, arrived at the International Space Station on Monday (April 13), bringing with it about 11,000 pounds of supplies.
Rise joined the Artemis 2 crew as a mascot of the moon, bearing 5.6 million names. But the mascot quickly took on a new meaning.
Artemis 2's Victor Glover and Christina Koch are all smiles after splashdown.
The close pass of Apophis is nothing to fear. Will you be watching on Friday, April 13, 2029, when this asteroid glides across the sky?
The Artemis 2 mission to the moon beamed back some incredible photos, and we've rounded up the best ones.
Astronomers have uncovered evidence that two planets collided around a young star, revealing how giant impacts sculpt baby solar systems.
A rare stargazing spectacle will unfold on Friday, April 13, 2029, as the asteroid Apophis passes closer than satellites over Europe and Africa in a true once-in-a-lifetime event.

Artemis II completed a 10-day journey around the Moon, carrying humanity farther into space than it has gone in over 50 years.
Scientists outline how a once-in-a-century solar storm could disrupt the technology modern society depends on.
Since July 2025, the European Space Agency’s pair of Proba-3 satellites has already created 57 artificial solar eclipses. So far, the mission has collected more than 250 hours of high-resolution videos of the Sun’s atmosphere, called the corona. That’s the same amount of observing time as about 5000 total solar eclipse campaigns carried out on Earth.
