The James Webb Space Telescope (JWST), launched on Christmas Day 2021, is already transforming our understanding of planets in our solar system and far beyond. A versatile satellite observatory, JWST has a clear-eyed view ...
Four billion years ago, the solar system was still young. Almost fully formed, its planets were starting to experience asteroid strikes a little less frequently. Our own planet could have become habitable as long as 3.9 billion ...
All stars, including the sun, have a finite lifetime. Stars shine by the process of nuclear fusion in which lighter atoms, such as hydrogen, fuse together to create heavier ones. This process releases vast quantities of energy ...
Life and supernovae don't mix.
The coming decade is expected to bring a veritable bonanza for the science of planets: space missions are scheduled to bring back samples of rock from the moon, Mars, the Martian moon of Phobos, and a primitive asteroid. ...
An Earth-like planet orbiting an M dwarf—the most common type of star in the universe—appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.
A global cross-disciplinary team of scientists led by UNSW Sydney researchers has developed the first comprehensive classification of the world's ecosystems across land, rivers and wetlands, and seas. The ecosystem typology ...
Action must be taken to conserve, restore and manage the diversity of microbes that live in soil environments to prevent their extinction, according to a Perspective article published in Nature Microbiology. The paper emphasizes ...
Recent exoplanet exploration has focused on the discovery of temperate rocky planets like the Earth, which are often called habitable planets. Most of the recent missions are targeting stars cooler than the sun. Such stars ...
An international team of astronomers reports the discovery of two new "super-Earth" exoplanets orbiting a nearby late-type M dwarf star. The newfound alien worlds, designated LP 890-9 b and LP 890-9 c, are slightly larger ...
