The 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam) captures a vibrant scene filled with swirls and stars reminiscent of Van Gogh's The Starry Night. This new cosmic masterpie
Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.
In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of
Seeds from South Africa's world-famous rooibos tea are headed to the International Space Station to see how they respond to space conditions in the first such experiment for Africa, organizers announc
Astronomers using NASA's James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in t
Listening to the "ringing" produced by black holes after they collide and merge could allow scientists to test Einstein's theory of general relativity under the most extreme conditions in the universe
Before Artemis astronauts land on the moon's surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking o
NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydr
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quic
