Magnetism on the Moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts to detect it in returned regolith samples blended together all of the rocks in those samples, leading to confusion about the source - whether they were caused by a strong inner dynamo in ages past, or by powerful asteroid impacts that magnetized the rocks they hit. A new study from Yibo Yang of Zhejiang University and Lin Xing of the Chinese Academy of Sciences, published recently in the journal Fundamental Research, shows that the right answer seems to be - a little of both.

The meaning of life has puzzled philosophers for millennia, but new research suggests it could be as simple as lending a helping hand

NASA will review data gathered during a simulated launch of the Artemis II rocket before revealing a new date for its upcoming moon mission

Researchers mimicked the air-trapping tricks of diving bell spiders to create aluminum that stays afloat—even when punctured

Dozens of routinely updated CDC databases have gone quiet. Here’s what states and medical societies are doing to preserve U.S. public health

SpaceX CEO Elon Musk says he’s making space-based artificial intelligence the “immediate focus” of a newly expanded company that not only builds rockets and satellites, but also controls xAI’s generative-AI software and the X social-media platform. That’s the upshot of Musk's announcement that SpaceX has acquired xAI.

Arp 220 is a well-known pair of galaxies that are merging. New ALMA observations of polarized light reveal the complex and powerful magnetic fields that shape the process.

NASA engineers temporarily stopped pumping liquid hydrogen fuel into the Artemis II rocket because of an apparent leak

Ants rely on scent to recognise their comrades, and when they are exposed to common air pollutants, other members of their colony react as if they are enemies

There’s no safe level of exposure to lead—but a small, strange study shows we’ve made incredible progress in recent decades

The tiny Foskeia pelendonum was a plant-eating dinosaur with a “weird” anatomy, scientists say

The sun is experiencing a violent solar storm, releasing one of the strongest solar flares seen in the past 30 years

This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger.

For the first time, researchers have found what seems to be a cloud of dark matter about 60 million times the mass of the sun in our galactic neighbourhood
