WebTheory-Defying Exoplanet Atmospheres Force a Rethink of Theories
6+ hour, 20+ min ago (953+ words) There's some misunderstanding among the public at large in regards to what a scientific theory is. They're statements about nature based on logic, evidence, and observation. But they're not papal pronouncements about reality that can never be challenged, lest the…...
Applied Sciences, Vol. 16, Pages 8527: Shear Mechanical Behavior of Lunar Regolith Simulant with Different Relative Densities Under Thermal–Mechanical Coupling
15+ hour, 25+ min ago (484+ words) The mechanical behavior of lunar regolith is crucial for lunar exploration projects, particularly drilling and sampling equipment. However, the extremely limited quantity of returned lunar regolith is insufficient for systematic macroscopic mechanical testing. Lunar regolith simulants are therefore widely used…...
Inside Mercury’s Raditladi and Eminescu craters, MESSENGER images revealed glacier-like flows that may consist of salts and other volatile-rich material preserved for more than a billion years—raising the possibility of buried niches analogous to salt deposits inhabited by extremophiles in Earth’s Atacama Desert.
23+ hour, 25+ min ago (1157+ words) MESSENGER mapped glacier-like runouts and hollows in two Mercury craters; salt-flow models explain their form and longevity, but neither composition nor habitability has been demonstrated....
A '20s farm boy couldn't afford a telescope, so he built one. Later, he discovered a planet.
1+ day, 2+ hour ago (550+ words) He even got to “visit” it in the late ’90s. Clyde Tombaugh’s passion for astronomy began in 1918, when he was only 12 years old, sparked by an uncle who had given him his first small telescope and a few astronomy textbooks. However,…...

Lindsey Jacobson Leads Earth Science Foresight
1+ day, 6+ hour ago (393+ words) Lindsey Jacobson's work helps NASA anticipate those disruptions before they happen and gives senior leaders options for managing them. "The way we do Earth science is changing." Jacobson and the NESSIE team support the Earth science satellite portfolio - dozens of…...
Astronomy Picture of the Day - JWST Images The Lion's Head Nebula
1+ day, 6+ hour ago (381+ words) Explanation: Are we looking at the future of our Sun? The James Webb Space Telescope captured today’s composite image of the Lion’s Head Nebula (NGC 2392) with its NIRCam and MIRI instruments. The Lion’s Head Nebula is the remnant of a…...
NASA's Pandora Mission Begins Scanning 20 Alien Worlds: What Scientists Are Looking For
1+ day, 8+ hour ago (502+ words) NASA's Pandora spacecraft began its science mission Aug. 25, roughly seven months after launching into low Earth orbit, with plans to study the atmospheres of at least 20 planets outside the solar system. The small satellite will look for atmospheric features including…...
