Webb and Hubble Space Telescopes Capture Detailed Views of DART Asteroid Impact

These images, Hubble on left and Webb on the right, show observations of the Didymos-Dimorphos system several hours after NASA’s Double Asteroid Redirection Test (DART) intentionally impacted the moonlet asteroid. It was the world’s first test of the kinetic impact technique using a spacecraft to deflect an asteroid by modifying its orbit. Both Webb and … Read more

NASA’s Juno spacecraft captures extraordinarily detailed images of Jupiter’s moon Europa

NASA’s Juno spacecraft has taken its first picture of Jupiter’s moon Europa — capturing the ice-encrusted surface in extraordinary detail. The image is the closest look at Europa that any spacecraft has provided in more than 20 years, when the US space agency’s Galileo came within 218 miles (351 km) of the surface in January 2000. … Read more

Scientists Identify the Source of the Planet Ceres’ Unexpected Geological Activity

Dwarf planet Ceres is shown in these false-color renderings, which highlight differences in surface materials. Images from NASA’s Dawn spacecraft were used to create a movie of Ceres rotating, followed by a flyover view of Occator Crater, home of Ceres’ brightest area. Credit: NASA/JPL Modeling reveals how Ceres powers unexpected geologic activity. According to Scott King, … Read more

Nasa’s James Webb telescope spots the oldest star clusters ever seen

Nasa’s James Webb Space Telescope has spotted the oldest star clusters ever seen. The clumps of millions of stars might include the first and oldest stars in the universe, according to the researchers who find them. The findings come from scientific analysis of Webb’s First Deep Field image. That image, which contains thousands of twinkling … Read more

Milky Way’s graveyard of dead stars found

Point cloud top-down and side-view of the galactic underworld of the Milky Way. Credit: University of Sydney The first map of the “galactic underworld”—a chart of the corpses of once massive suns that have since collapsed into black holes and neutron stars—has revealed a graveyard that stretches three times the height of the Milky Way, … Read more

Scientist resolves one of the holy grails of physical chemistry after 17 years of research
