1:00 NASA discovers new Earth-sized planet in a habitable zoneNASA had previously discovered three other planets in the same system, one of which was also in the habitable zone.Scientists from NASA announced Tuesday that they discovered an Earth-size planet orbiting its star's habitable zone. ...
Here we report the discovery of a temperate Earth-sized planet orbiting the cool M6 dwarf LP 791-18. The newly discovered planet, LP 791-18d, has a radius of 1.03 ± 0.04 R⊕ and an equilibrium temperature of 300–400 K, with the permanent night side plausibly allowing for ...

A new planet orbiting a small cold star, a mere 55 light years away has been discovered by astronomers atMIT, theUniversity of Liège, and elsewhere. Although the nearbyexoplanetis similar to Earth in its size and rocky composition, that’s where the similarities end. The key difference is...
While venturing beyond our planet captures the imagination,the true impact of space exploration may be felt much closer to home. Public perception often frames space exploration as a distant endeavor with limited relevance to terrestrial challenges. However, this perspective overlooks the substantial cont...
Astronomers discovered a world beyond our solar system, a exoplanet, that is around the size of Earth and could possibly harbor conditions that might allow life to thrive. It's called Wolf 1069 b.
