A new look at TRAPPIST-1e, an Earth-sized, habitable-zone exoplanet
https://phys.org/news/2025-12-trappist-1e-earth-sized-habitable.htmlOf the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention of scientists. This planet orbits the star within the "Goldilocks zone"—a distance where water on its surface is theoretically possible, but only if the planet has an atmosphere. And where there is water, there might be life. ... read full post

Boiling oceans may lurk beneath the ice of solar system's smallest moons
https://phys.org/news/2025-11-oceans-lurk-beneath-ice-solar.htmlThe outer planets of the solar system are swarmed by ice-wrapped moons. Some of these, such as Saturn's moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky core and could be the best places in our solar system to look for extraterrestrial life. A new study published Nov. 24 in Nature Astronomy sheds light on what could be going on beneath the surface of these worlds and provides insights into how their diverse geologic features may have formed. ... read full post

JWST captures stunning 3D view of a planet’s scorching atmosphere
https://www.sciencedaily.com/releases/2025/11/251102011152.htmLed by researchers at the University of Maryland and Cornell University, the study charts temperatures across WASP-18b, a massive gas giant classified as an "ultra-hot Jupiter" located 400 light-years from Earth. The team applied a method known as 3D eclipse mapping, also called spectroscopic eclipse mapping, marking the first time this technique has been used to build a full 3D temperature map. The work expands on a 2D eclipse map the group released in 2023 using highly sensitive observations from NASA's James Webb Space Telescope (JWST). ... read full post

Open journal question regarding Cosmology paper
So, if an academic paper is published in an open journal by an average citizen with an obsession for learning from online sources. So, there are no credentials but a decent work history. A prestigious college downloads the paper. What are the possible reasons?
