Joint ground- and space-based observations reveal Saturn-mass rogue planet
Washington DC (SPX) Jan 03, 2026 Simultaneous ground- and space-based observations of a newly discovered free-floating planet have enabled direct measurement of its mass and distance from Earth, according to a new study. The findings offer insights into the diverse and dynamic pathways by which planets can be cast adrift into interstellar space. Although studies to date have only revealed a handful of such free-floating planets, detections are expected to increase in the coming years, particularly with the NASA Nancy Grace Roman ... read more |

Supernova mixing traced as source of key life elements
Tokyo, Japan (SPX) Dec 05, 2025 Kyoto University and Meiji University researchers have used the XRISM X-ray satellite to quantify chlorine and potassium in the Cassiopeia A supernova remnant, addressing a longstanding gap in how the universe produced these life-related elements. The work examines why current stellar models yield only about one-tenth of the chlorine and potassium inferred from observations across the cosmos. Chlorine and potassium are odd-Z elements, each with an odd number of protons, and they play important rol ... read more 
TRAPPIST 1 flares mapped to probe planetary habitabilityBoulder CO (SPX) Dec 05, 2025 TRAPPIST-1, a small star about 40 light-years from Earth in the constellation Aquarius, produces flares roughly six times per day, and this activity complicates efforts to evaluate whether its plane ... more |
