Analyzing a sample of 300 of the best-characterized planetary systems among the more than 1,000 known in the Milky Way, an international research team led by the Italian National Institute for Astrophysics (INAF) has discovered that the multiplanet systems identified so far belong to two distinct "families."

Structure in the unstructured: New phenomenon discovered in the solar wind

Turbulence is ubiquitous and occurs every day, such as when milk is stirred into coffee or in the stormy motions of the ocean and the atmosphere. Media in space and astrophysical systems can also develop turbulence, but the physics is different because the medium is in an ionized

Copper-resistant bacteria complicate efforts to keep ship hulls clean

Marine bacteria have evolved to bypass the copper-based coatings applied to ship hulls to stop the growth of barnacles, algae and other marine life. This necessitates new methods for managing biofouling—the unwanted accumulation of marine organisms—on ship hulls.

Webb spots possible early-universe supernova just days after it happened

The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was found without the help of gravitational lensing. JWST ob
