A Falcon 9 rocket carrying 24 Starlink spacecraft lifted off from NASA’s Kennedy Space Center on Tuesday (Nov. 26) at 11:41 p.m. EST (0441 GMT on […]
Magnetic tornadoes on Jupiter are spawning Earth-size storms (Image Credit: Space.com) Planetary scientists have issued a tornado warning for Jupiter, with the discovery that magnetic vortices twisting down from the planet’s ionosphere into its deep atmosphere are resulting in giant, ultraviolet-absorbing anticyclones each the size of our Earth. These anticyclonic storms manifest […]
International Space Station dodges 2nd piece of space junk in 6 days (Image Credit: Space.com) The International Space Station just dodged a piece of debris for the second time in less than a week. Russia’s robotic Progress 89 freighter, which has been docked to the ISS since August, fired its thrusters for […]
XRISM mission looks deeply into ‘hidden’ stellar system (Image Credit: Phys.org) Cygnus X-3 is a high-mass binary consisting of a compact object (likely a black hole) and a hot Wolf-Rayet star. This artist’s concept shows one interpretation of the system. High-resolution X-ray spectroscopy indicates two gas components: a heavy background outflow, or […]

Planetary scientist proposes an alternative theory for what lies beneath the surfaces of Uranus and Neptune (Image Credit: Phys.org) Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are generated, and a lower, non-convecting hydrocarbon-rich […]
Sombrero Galaxy dazzles in new Webb images and video (Image Credit: Phys.org) This image compares the view of the famous Sombrero Galaxy in mid-infrared light (top) and visible light (bottom). The James Webb Space Telescope’s MIRI (Mid-Infrared Instrument) reveals the smooth inner disk of the galaxy, while the Hubble Space Telescope’s visible […]

The five member dwarf galaxies are designated, with their redshift information. Credit: Paudel et al., 2024. Astronomers from the Yonsei University […]
Record-breaking run on Frontier sets new bar for simulating the universe in exascale era (Image Credit: Phys.org) A small sample from the Frontier simulations reveals the evolution of the expanding universe in a region containing a massive cluster of galaxies from billions of years ago to present day (left). Red areas show […]
The engine of Japan’s flagship new small rocket explodes during a test for a second time (Image Credit: Phys.org) In this photo provided by Japan Aerospace Exploration Agency (JAXA), smoke and fire are seen during a combustion test of an engine for new small Japanese rocket Epsilon S at Tanegashima Space Center, […]
