On Sunday, Aug. 30, the Nancy Grace Roman Space Telescope is expected to launch from NASA’s Kennedy Space Center in Florida. The observatory will join the Hubble Space Telescope, launched in 1990, and the James Webb Space Telescope, launched in 2021, in scanning the vastness of space and potentially finding answers to longstanding mysteries of […]

In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA’s James Webb Space Telescope are helping astrophysicists probe deep cosmic mysteries, including the evolution of black holes and galaxies.

During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the sun’s outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant being in exactly the right place at the right time.

The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated as Dyson spheres.

Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet’s upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, yet the chemical identity of the material responsible—the “unknown absorber”—remains unresolved.

Researchers have discovered a thermal asymmetry deep beneath the surface across Mars’ southern hemisphere. Based on gravitational measurements that provide clues to the Red Planet’s interior structure, Mars’ southern interior is around 200 to 400 degrees Celsius warmer than the planet’s northern half and partially molten. The surprising finding adds context to Martian history and […]

Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes that occur there. Led by the University of California, Los Angeles (UCLA), an international research team has produced the first experimental verification of a theoretically predicted flow state deemed characteristic of the interiors of […]
