For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ten hours, while accounting for a significant fraction of the solar system’s rotational energy. Using the W.M. Keck Observatory on Maunakea, Hawai’i, a team […] This image captured by U.S.-Indian Earth satellite NISAR on Nov. 10, 2025, shows Washington’s Mount St. Helens. The image is cropped from a much larger swath spanning the Pacific Northwest on a cloudy day; NISAR’s L-band SAR instrument is able to peer through the clouds at the surface below. Go to Source […] More than 50 years after humans first flew around the moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes. Go to Source The early universe is absolutely so far outside our understanding of how the world works it’s hard to describe in words. Back then, the cosmos wasn’t filled with stars and galaxies but with a boiling soup of quarks and gluons, with a few microscopic black holes thrown in, occasionally detonating like depth charges. That’s the […] Now more than halfway to the moon, the Artemis II astronauts prepared for their historic lunar fly-around to push deeper into space than even the Apollo astronauts. Go to Source The Artemis astronauts have taken in sights of the moon never before seen by human eyes, crew members reported on Sunday as their spacecraft crossed the two-thirds mark on their journey to a long-anticipated lunar flyby. Go to Source In about 5 to 8 billion years, our sun is expected to evolve into a white dwarf—an extremely dense, Earth-sized stellar remnant that has exhausted its fuel and shed its outer layer. But while our sun is a solitary star, research over the past 15 years has demonstrated that binary or multi-star systems are far […] As four astronauts whiz toward a flyby of the moon, looking out for them are mission control experts using cutting-edge technology and lessons learned from the Apollo program 50 years ago. Go to Source They’re sipping smoothies, snapping phone pics, dealing with crashed email and fixing broken toilets: astronauts, they’re just like us. Go to Source The Artemis 2 astronauts have passed the halfway point between Earth and the moon on Saturday as they sped toward a planned lunar flyby, with NASA releasing initial images of Earth taken from inside the Orion spacecraft. Go to Source NASA is joining international partners to hunt for ice on the moon in support of future human exploration. The agency is providing a water-detecting instrument, the Neutron Spectrometer System (NSS), to the Lunar Polar Exploration (LUPEX) mission led by JAXA (Japan Aerospace Exploration Agency) and ISRO (Indian Space Research Organization). Go to Source […] Artemis 2 astronaut Jeremy Hansen felt like he was “falling out of the sky” as his spacecraft followed its complex flight path to the moon, the Canadian said in a Saturday video call. Go to Source The Artemis II astronauts have captured our blue planet’s brilliant beauty as they zoom ever closer to the moon. Go to Source We’re getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we’re looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That’s a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose […] The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie’s Cong Liu and Ronald Cohen. Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found […] |
