Artemis

NASA’s Artemis II mission will transport four astronauts around the Moon, bringing the agency one step closer to sending the first astronauts to Mars. Throughout Artemis II, astronaut voice, images, video, and vital mission data must traverse thousands of miles, carried on signals from NASA’s communications systems.

NASA Telescopes Spot Surprisingly Mature Cluster in Early Universe

A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will […]

NASA Webb Pushes Boundaries of Observable Universe Closer to Big Bang

NASA’s James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed 280 million years after the big bang. By now Webb has established that it will eventually surpass virtually every benchmark […]

Discovery Alert: An Ice-Cold Earth?

The Discovery A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars. Key Facts Scientists continue to mine data gathered by NASA’s Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the […]

Webb Data Reveals Dark Matter

This image from NASA’s James Webb Space Telescope, containing nearly 800,000 galaxies, is overlaid with a map of dark matter, represented in blue. Brighter blue areas indicate a higher density of dark matter. Researchers used Webb data to find the dark matter — which is invisible — via its gravitational influence on regular matter. The […]
