A new class of supermassive black holes embedded in a thick gas shell could explain small red dots in images from the James Webb Space Telescope. Go to Source A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in response to the sun. Understanding the physics of the exosphere is a key step toward forecasting dangerous conditions in near-Earth space, a requirement for protecting […] The first model of the European Space Agency’s (ESA) reusable rocket demonstrator Themis is standing at its launch pad in Kiruna, Sweden. Go to Source Researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences have revealed for the first time how gas flows from vast distances toward the disk surrounding a nascent massive star in the process of star formation. Go to Source Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit over its entire lifetime. Yet, despite decades of observations, key mysteries remain unsolved: What powers the prompt emission? What is the […] Of the many roads leading to successful Artemis missions, one is paved with high-tech computing chips called superchips. Along the way, a partnership between NASA wind tunnel engineers, data visualization scientists, and software developers verified a quick, cost-effective solution to improve NASA’s SLS (Space Launch System) rocket for the upcoming Artemis II mission. This will […] Before we get to Mars, we’re going to have to practice. And develop radical leaps in technology, but also practice. A Mars mission will be utterly unlike anything attempted by humanity. We’re talking about a group of settlers, maybe as few as an initial team of four, traveling over a hundred million miles away from […] Much as we may treasure and proclaim our independence, we actually live in a protective bubble called the heliosphere. Go to Source Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe’s mass. As it cannot be detected and studied using conventional experimental techniques, the nature and composition of dark matter have not yet been uncovered. Go to Source […] A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA’s Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the Big Bang. Go to Source A study of Saturn’s atmospheric structure using data from the James Webb Space Telescope (JWST) has revealed complex and mysterious features unseen before on any planet in our solar system. Go to Source Day and night will get equal time for a brief moment Monday as much of the world heads into fall. Go to Source NASA’s Deep Space Optical Communications technology has successfully shown that data encoded in lasers can be reliably transmitted, received, and decoded after traveling millions of miles from Earth at distances comparable to Mars. Nearly two years after launching aboard the agency’s Psyche mission in 2023, the technology demonstration recently completed its 65th and final pass, […] A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the universe created by a mysterious substance known as dark matter. Go to Source A team of researchers from Kent have demonstrated that it is possible to grow tea in lunar soil as part of a wider field of work to explore how future astronauts living and working on the moon can grow their own food.
