A space walking robot could build a giant telescope in space (Image Credit: Phys.org) Artist impression of the James Webb Space Telescope. Its design and construction were made more complicated and expensive because it had to fit into the nosecone of the rocket that launched it. Assembling telescopes in space could be […]
Spectral method can compute tidal effects on planet and moon interiors (Image Credit: Phys.org) The puzzling, fascinating surface of Jupiter’s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA’s Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that […]
Astrophysicists use echoes of light to illuminate black holes (Image Credit: Phys.org) Due to gravitational lensing, the photons from a single flash of light near a black hole follow winding paths. Some follow the trajectory of the blue line, where they take a direct path to the observer. Others orbit around the […]
Astronomers discover a new repeating fast radio burst (Image Credit: Phys.org) Total daily exposure time (UTC and topocentric at CHIME near Penticton, Canada) at the position of FRB 20240209A (blue points) and detection times of the repeat bursts (gray vertical lines).

Chinese rover finds evidence of ancient Martian ocean (Image Credit: Phys.org) The theory that an ocean covered as much as a third of Mars billions of years ago has been controversial among scientists. A Chinese rover has found new evidence to support the theory that Mars was once home to a vast […]
On ancient Mars, carbon dioxide ice kept the water running. Here’s how (Image Credit: Space.com) A lone researcher may have figured out how Mars was able to support rivers and seas even after the planet had begun to grow cold and its atmosphere thin, and it’s all thanks to a cycle of […]
NASA Wants to Bring Welding Back to Space After 50 Years—This Time With Lasers (Image Credit: Gizmodo-com) As space agencies look to establish human habitats on the Moon and Mars, astronauts must be equipped with tools to manufacture structures in space. But rather than packing a traditional tool box to space, NASA […]
3D map reveals our solar system’s local bubble has an ‘escape tunnel’ (Image Credit: Space.com) Using data from the eROSITA All-Sky Survey, astronomers have created a 3D map of the low-density bubble of X-ray-emitting, million-degree hot gas that surrounds the solar system. The investigation has revealed a large-scale temperature gradient within this bubble, […]
Synspective starts full-scale ops at the Yamato Technology Center for SAR satellite production (Image Credit: Sat News) Synspective Inc., a provider of Synthetic Aperture Radar (SAR) satellite data and analytics solutions, has announced that the Yamato Technology Center, a new manufacturing site for small SAR satellites, began full-scale operations in September — […]
SpaceX launches 23 more Starlink satellites from Florida (video, photos) (Image Credit: Space.com) SpaceX launched yet another batch of its Starlink internet satellites this afternoon (Nov. 7) from Florida’s Space Coast. A Falcon 9 rocket carrying 23 Starlink spacecraft lifted off today from Cape Canaveral Space Force Station at 3:19 p.m. EST […]
