In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the moon, where NASA’s Artemis program is returning humans, preparing for Mars and shaping the future of space […]

The Mars we know today is a cold, dry world of dust and rocks. However, around 3.8–3.6 billion years ago, it may have looked very different. Geological and mineral evidence suggests that, in its distant past, the planet experienced periods warm and wet enough for water to exist on its surface, potentially forming rivers, lakes […]

New research has found that the rate of hip fractures among astronauts after spaceflights lasting more than 90 days was higher than after shorter spaceflights or among people who were not astronauts. The findings of the study in Mayo Clinic Proceedings, underscore the need for expanded assessment of astronauts’ long-term skeletal health.

A team of researchers led by the National Astronomical Observatory of Japan discovered unexpectedly intricate magnetic structures above quiet-sun regions by observing the sun with the balloon-borne solar observatory Sunrise-III during its 2024 flight in Earth’s stratosphere. The work is published in The Astrophysical Journal Letters.
