Scientists have produced the first global map and analysis of small mare ridges (SMRs) on the moon, a characteristic geological feature of tectonic activity. Published in The Planetary Science Journal Dec. 24, 2025, the analysis performed by scientists at the National Air and Space Museum's Center for Earth and Planetary Studies and colleagues reveals for the first time that SMRs are geologically young and are widespread across the lunar maria—the vast, dark plains on the moon's surface. The team's discovery of how SMRs form introduces a new set of potential moonquake sources that could affect future site selections for lunar landings.

One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed by objects closer to us. Under the right conditions, gravitational lensing can act as a kind of natural telescope, brightening and magnifying the light of distant objects. Astronomers have used this trick to observe some of the most distant galaxies in the universe. But astronomers have also thought about using this effect a little closer to home.

Dive into Rubin's Cosmic Treasure Chest — there's so much to explore

Astronomers have discovered a new object that originated outside of our Solar System — only the third to be found.

Honda Global - Honda R&D Co., Ltd., a research and development subsidiary of Honda Motor Co., Ltd., today conducted a launch and landing test of an experimental reusable rocket*1 (6.3 m in length, 85 cm in diameter, 900 kg dry weight/1,312 kg wet weight) developed independently by Honda. The test was completed successfully, the first time Honda landed a rocket after reaching an altitude of 300 meters.
