A small planet orbiting its host star – Grok via Astrobiology.com Future telescopes will survey temperate, terrestrial exoplanets to estimate the frequency of habitable (ηHab) or inhabited (ηLife) planets. This
An integrated approach to date bacterial evolution and reconstruct the history of oxygen adaptation. We inferred a bacterial timetree by integrating genomic, fossil, and geochemical data and linking oxygen tolerance
Idealized ice growth and stratigraphy at onset of snowball Earth. Note vertical exaggeration. (A) Marine-terminating terrestrial ice sheet with calving ice front prior to ice-albedo runaway into snowball glaciation. The
Photo of Nebula NGC 1333. The James Webb telescope detected interstellar ice there, which could be the origin of stars and planets. The study shows that this ice was apparently
Artist’s depiction of water rushing into Mars’ Jezero Crater, which billions of years ago was the site of a delta. (Credit: NASA/JPL-Caltech) Visit ancient Mars—a surprisingly temperate planet where snow
A disintegrating planet orbits a giant star. Credit Jose-Luis Olivares, MIT MIT astronomers have discovered a planet some 140 light-years from Earth that is rapidly crumbling to pieces. The disintegrating
Integrated intensity maps of the 0.9 mm dust continuum emission (taken from Rosotti et al. (2020)) and molecular line emission from the HD 100453 disk. For the line maps, the
The dominant phosphorous reservoirs throughout the HD 100546 disk. Left-hand panel: a map of the calculated disk temperature structure, which dictates phosphorous mineral stability. Normalised height above midplane is given
CN measurement limits in the exocomet frame for a CN line width of 2.7, 10 and 20 km s−1. Contours show signal-to-noise upper limits. — astro-ph.EP The young (23 Myr)
