Southwest Research Institute scientists have compiled 41 solar occultation observations of Saturn’s rings from the Cassini mission. The compilation, published recently in the scientific journal Icarus, will inform future investigations of the particle size distribution and composition of Saturn’s rings, critical elements to understanding their formation and evolution. Dr. Stephanie Jarmak, a researcher in the ...
Pictures of the sky can show us cosmic wonders, while movies can bring them to life. Films from NASA’s NEOWISE space telescope reveal motion and change across the sky. Every six months, NASA’s Near-Earth Object Wide Field Infrared Survey Explorer, or NEOWISE, spacecraft completes one trip halfway around the Sun, taking images in all directions. Stitched ...
Are we alone in the universe? An answer to that age-old question has seemed tantalizingly within reach since the discovery of ice-encrusted moons in our solar system with potentially habitable subsurface oceans. But looking for evidence of life in a frigid sea hundreds of millions of miles away in deep space poses tremendous challenges. The science ...
NASA’s InSight mission, expected to end shortly, saw a recent drop in power generated by its solar panels as a continent-size dust storm swirls over Mars’ southern hemisphere. First observed on September 21, 2022, by NASA’s Mars Reconnaissance Orbiter (MRO), the storm is roughly 2,175 miles (3,500 kilometers) from InSight and initially had little impact ...
As NASA prepares to usher in a new form of planetary defense, one Johns Hopkins engineer will be eagerly awaiting the big collision with an asteroid that she is helping orchestrate. Elena Adams, the mission systems engineer at the Johns Hopkins Applied Physics Laboratory, and her team will spend the next two weeks carefully observing Didymos, ...
After being installed on the exterior of the International Space Station, NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission has provided its first view of Earth. The milestone, called “first light,” took place at 7:51 p.m. PDT (10:51 p.m. EDT) on July 27 as the space station passed over Western Australia. Developed by NASA’s Jet ...
On the heels of the release of the first images from NASA’s James Webb Space Telescope, data from the telescope’s commissioning period is now being released on the Space Telescope Science Institute’s Mikulski Archive for Space Telescopes. The data includes images of Jupiter and images and spectra of several asteroids, captured to test the telescope’s instruments before science operations ...
The first images from NASA’s new Webb space telescope unveiled this week include a new look at the universe, expanding our view of the galaxy as we know it. The images include a high-resolution “window” to millions of stars through the Milky Way’s dust, a new look at galaxies lightyears away for the first time ...
Our world today would not manage to survive without technology, whether it is as basic as electricity or as advanced as the Internet. Businesses all across the world use these to get work done on a regular basis. So can solar storms really knock all of these out? What if our entire globe went dark, ...
NASA’s James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star. The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of ...
