New footage shows one of NASA's WB-57 research jets spewing out flames and smoke as it skids across a runway during an emergency landing near Houston. The veteran aircraft was due to play a small role in the Artemis II mission.

Astronomers suspect that a massive metallic cloud swirling in a nearby star system could be hiding a giant planet or dwarf star from view, after it drastically dimmed a sun-like star for around nine months.

ESA's Proba-3 mission, made up of twin spacecraft capable of aligning to create artificial eclipses, has captured "rare" footage of three solar prominences erupting from the sun's mysteriously hot atmosphere.

Earth's magnetic field was struck by a "severe" solar storm Monday (Jan. 19), triggering vibrant auroras in the U.S. and large parts of Europe. The storm broke a record that had stood for more than two decades.

New photos show off NASA's newly constructed Roman Space Telescope, which will soon help researchers unravel the mysteries of the cosmos. Experts have also revealed when the next-gen spacecraft is set to launch and begin collecting data.

A new study reveals a rare-breaking white dwarf star, dubbed RXJ0528+2838, that is somehow generating a rainbow-like "bow shock" as it zooms through the Milky Way. The cosmic zombie is also ripping apart its partner star like a black hole.

New satellite photos reveal that one of the world's largest and longest-lived icebergs, A23a, has developed vibrant blue striations on its surface. The striking snaps hint that the "megaberg" will soon disappear forever, ending a surprisingly eventful four-decade-long saga.

Recently discovered Comet C/2025 R3 (PanSTARRS) will make its closest approach to the sun and Earth in late April and could potentially be visible to the naked eye. It may end up being the brightest comet of the year.

The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar flares, including a hidden X-class outburst, a new paper reveals. The study sets a record for the longest continuous observation of a single active region on our home star.

Researchers have proposed a theoretical timepiece, dubbed the "CRASH Clock," which tells us how quickly satellites would start colliding if they lost the ability to avoid each other, such as during a powerful solar storm. And its value is rapidly decreasing.

A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The thought experiment suggests that we need to avoid human biases in our search for extraterrestrial life.

A new study reveals that tiny fragments of Earth's atmosphere are transported to and absorbed by the moon via gusts of solar wind and our planet's magnetic field, upending a 20-year-old theory based on NASA's Apollo lunar samples.
