Moonquakes shook Apollo 17’s landing zone—and they could challenge the safety of future lunar outposts. Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years...
A high-precision thermal wavefront system called FROSTI allows LIGO and future detectors to operate at megawatt-scale laser power without degrading signal quality. This breakthrough will greatly expand our ability to detect black hole and neutron star mergers across the universe. Credit: Shutterstock
FROSTI revolutionizes mirror control in gravitational-wave detectors, opening the door to a far deeper view of the cosmos. FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power. By using custom thermal patterns, it preserves mirror shape without introducing noise, allowing detectors to operate at higher sensitivities. This leap enables future observatories like Cosmic Explorer to see deeper into the cosmos...
Nov. 19 image obtained by Pau Montplet from Breda (Girona) using a C6 telescope at f:7. Original image is in the lower right inset, while a false color 0.6º wide Larson-Sekanina filtered image at 9º shows 3I in negative to remark the antitail pointing to the subsolar point, and several jets getting out from the false nucleus. Two additional arrows mark wavy structures in the jets. Image resolution is 0.7 arcsec/pix. Credit: arXiv (2025). DOI: 10.48550/arxiv.2511.19112
Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes...
A team of Japanese and US scientists have discovered the bio-essential sugars ribose and glucose in samples of asteroid Bennu that were collected by NASA’s OSIRIS-REx mission. This finding builds on the earlier discovery of nucleobases (the genetic components of DNA and RNA), phosphate, and amino acids (the building blocks of proteins) in the Bennu samples, showing that the molecular ingredients of life could have been delivered to early Earth by meteorites.

The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life...
