The exoplanet K2-18b is generating headlines because researchers announced what could be evidence of life on the planet. The JWST detected a pair of atmospheric chemicals that on Earth are produced by living organisms. The ...
Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with ...
A team from the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has developed a machine-learning model that predicts potential planetary systems with Earth-like planets. The model could ...
About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species.
All planets are made of gas, ice, rock and metal, and models of how planets form usually assume that these materials don't react chemically with each other. But what if some of them do?
Astrophysicists have once again enriched our knowledge of the cosmos with a new discovery: two small planets orbiting TOI-1453. Located at around 250 light years from Earth in the Draco constellation, this star is part of ...
