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.

A team of researchers, including those at the University of Tokyo, discovered that liquid water once flowed on the asteroid that spawned near-Earth asteroid Ryugu more than a billion years after it first formed. The finding, based on tiny rock fragments returned by the Hayabusa2 spacecraft of the Japan Aerospace Exploration Agency (JAXA), overturns long-held assumptions that water activity on asteroids only occurred in the earliest moments of solar system history. This could impact models which include the formation of the Earth.

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.

In a newly published study in Astrophysical Journal Letters, researchers used what they said are the largest-ever samples of special galaxies called Lyman-alpha emitters to study how galaxies clumped together over billions of years. In doing so, they gained an improved understanding of how galaxies relate to the surrounding dark matter and how they evolve over time.

Public confidence in U.S. health and science agencies has dropped since the inauguration of President Donald Trump, according to a new survey by the Annenberg Public Policy Center. The survey also finds that most Americans lack confidence that Health and Human Services Secretary Robert F. Kennedy Jr. is providing the public with trustworthy information on matters of public health.

Astronomers using observatories around the world, including the Gemini South telescope, the SOAR telescope and the Víctor M. Blanco 4-meter Telescope funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, have found that the asteroid 1998 KY26 is almost three times smaller and spinning much faster than previously thought. The asteroid is the 2031 target for Japan’s Hayabusa2 extended mission, and the new observations offer key information for the mission’s operations.
