Stopping algae blooms with bacteria-busting buoys

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ten hours, while accounting for a significant fraction of the solar system's rotational energy. Using the W.M. Keck Observatory on Maunakea, Hawai'i, a team of astronomers tested this predicted relationship by studying 32 gas giants and brown dwarfs in distant star systems—6 giant planets larger tha

This image captured by U.S.-Indian Earth satellite NISAR on Nov. 10, 2025, shows Washington's Mount St. Helens. The image is cropped from a much larger swath spanning the Pacific Northwest on a cloudy day; NISAR's L-band SAR instrument is able to peer through the clouds at the surface below.

More than 50 years after humans first flew around the moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes.
