Evoking the experimental nature of flight testing and the spirit of aeronautical exploration, Quesst is what NASA is calling its mission to enable supersonic air travel over land. This new moniker – complete with an extra “s” to represent “supersonic” – draws its inspiration from NASA’s long legacy of supersonic flight research. Quesst, which rep...
This new NASA Hubble Space Telescope image spotlights the giant elliptical galaxy, UGC 10143, at the heart of galaxy cluster, Abell 2147, about 486 million light-years away in the head of the serpent, the constellation Serpens. UGC 10143 is the biggest and brightest member of Abell 2147, which itself may be part of the much larger Hercules Supercluster of ga...
On May 11, 2022, the National Oceanic and Atmospheric Administration, or NOAA, shared the first images of the Western Hemisphere from its Geostationary Operational Environmental Satellite-T (GOES-T). Later designated GOES-18, the satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth. Launched by NASA on March 1, GOES...

Endurance is bringing Crew-3 back to Earth, including NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, and ESA (European Space Agency) astronaut Matthias Maurer, aft...
Black holes are hard to find. They have such strong gravity that light can’t escape them, so scientists must rely on clues from their surroundings to find them. When a star weighing more than 20 times the Sun runs out of fuel, it collapses into a black hole. Scientists estimate that there are tens of millions of these black holes dotted around the Milky Way,...
May 2-6, 2022, is Teacher Appreciation Week!
