Titan, Saturn’s largest moon, is a fascinating world that is unique among moons of the outer solar system. It’s shrouded in a thick, hazy atmosphere rich in nitrogen and methane and it’s the only moon with a substantial atmosphere and the only place besides Earth known to have stable bodies of surface liquid. Go to […] A Southwest Research Institute-led study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is only 73 light years from Earth and could serve as a “Rosetta Stone” for understanding an entire […] Scientists have hypothesized since the 1960s that the sun is a source of ingredients that form water on the moon. When a stream of charged particles known as the solar wind smashes into the lunar surface, the idea goes, it triggers a chemical reaction that could make water molecules. Go to Source […] Imagine a Slushee composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted slushballs, dubbed “mushballs,” raining down like hailstones during a thunderstorm, illuminated by intense flashes of lightning. Go to Source A strong solar storm headed to Earth could produce colorful aurora displays across more U.S. states than usual Tuesday night. Go to Source We all know that black holes can devour stars, rip them apart and consume their remnants. But that only happens if a star passes too close to a black hole. What if a star gets close enough to a star to experience strong tidal effects, but not close enough to be immediately devoured? This scenario […] What kind of mission would be best suited to sample the plumes of Saturn’s ocean world, Enceladus, to determine if this intriguing world has the ingredients to harbor life? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC 2025) hopes to address as a team of researchers investigated […] Up until recently, astronomy was reliant entirely on electromagnetic waves. While that changed with the confirmation of gravitational waves in 2016, astronomers had developed fundamental frameworks in the electromagnetic spectrum by that point. Go to Source In 2021, the Office of the Director of National Intelligence (ODNI) released a report detailing recently-declassified information on unidentified aerial phenomena (UAP). Since then, the Department of Defense has released annual reports on UAP through the All-domain Anomaly Resolution Office (AARO). Nevertheless, there is still a lack of publicly available scientific data. To address this, […] Black holes are fundamental to the structure of galaxies and critical in our understanding of gravity, space, and time. A stellar mass black hole is a type of black hole that forms from the gravitational collapse of a massive star at the end of its life cycle. These black holes typically have masses ranging from […] Black holes come in a range of sizes. Stellar mass black holes form from the collapse of massive stars, typically weighing between 5 and 100 times the mass of our sun, and are scattered throughout galaxies. At the other extreme are the supermassive black holes that lurk at the center of most galaxies, including our […] The universe doesn’t come with an instruction manual—but if it did, University of Missouri Assistant Professor Charles Steinhardt suspects a few pages are missing. Either the universe has been playing by different rules all along, or humanity has been reading the script wrong. Go to Source The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the sun. A Southwest Research Institute-led team of scientists sought the source of this unusual occurrence to better understand the mechanisms that drive solar energetic particles (SEPs) that permeate our solar system. SEPs are high-energy, accelerated particles including […] The nominee for NASA’s top job, billionaire spacewalker Jared Isaacman, outlined his vision for space exploration on Wednesday that prioritizes sending astronauts to Mars without giving up on the moon. Go to Source A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf galaxies, which has long been debated. The study was published in Nature, and led by Postdoctoral Researcher Mélina Poulain from the University of […] |
