NASA/Brandon Hancock NASA’s Orion spacecraft, which will carry the Artemis II crew around the Moon, sits at the launch pad on Jan. 17, 2026, after rollout. It rests atop the SLS (Space Launch System) rocket. Orion can provide living space on missions for four astronauts for up to 21 daysContinue Reading
NASA’s IMAP (Interstellar Mapping and Acceleration Probe) began its two-year primary science mission on Feb. 1 to explore and map the boundaries of our heliosphere — the protective bubble created by the solar wind that encapsulates our solar system. The mission, which launched on Sept. 24, 2025, relies on 10Continue Reading

The Sun emitted three strong solar flares on Feb. 1, peaking at 7:33 a.m. ET, 6:37 p.m. ET, and 7:36 p.m. ET. The Sun emitted a fourth strong solar flare on Feb. 2, peaking at 3:14 a.m. ET. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured images ofContinue Reading
Scientists say increasing shipping traffic is interfering with the whales’ ability to hunt and communicate. To protect the animals, conservation groups are urging the International Maritime Organization to instate mandatory measures to reduce underwater noise. By Teresa Tomassoni For most of their evolutionary history, narwhals have relied more on soundContinue Reading
Despite growing into the largest animals ever to walk on land, sauropods began life small, exposed, and alone. Fossil evidence suggests their babies were frequently eaten by multiple predators, making them a key part of the Jurassic food chain. This steady supply of easy prey may explain why early predatorsContinue Reading

A spray-on coating to keep power lines standing through an ice storm may not be the obvious fix for winter outages — but it’s exactly the kind of innovation that happens when MIT students tackle a sustainability challenge. “The big threat to the power line network is winter icing thatContinue Reading
Decades of reliability and major savings—despite high up-front costs—suggest a future for geothermal, an energy source that also makes sense for oil and gas companies to invest in. Interview by Jenni Doering, Living on Earth From our collaborating partner Living on Earth, public radio’s environmental news magazine, a conversation betweenContinue Reading
