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 […]
NASA’s Juno Measures Thickness of Europa’s Ice Shell
Results from the solar-powered spacecraft provide a new measurement of the thickness of the ice shell encasing the Jovian moon’s ocean. Data from NASA’s Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter’s moon Europa. Using the spacecraft’s Microwave Radiometer (MWR), mission scientists determined that the shell averages about 18 miles (29 […]
NASA Launches Its Most Powerful, Efficient Supercomputer
NASA is announcing the availability of its newest supercomputer, Athena, an advanced system designed to support a new generation of missions and research projects. The newest member of the agency’s High-End Computing Capability project expands the resources available to help scientists and engineers tackle some of the most complex challenges in space, aeronautics, and science. […]
NASA’s James Webb Space Telescope Finds Crystal-Spewing Protostar
The NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope captured the actively forming protostar EC 53 (circled at left) in the Serpens Nebula in this image released on Jan. 21, 2026. Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form […]
