Webb provides the first vertical view of the planet’s ionosphere, revealing auroras shaped by its tilted magnetic field. For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb’sContinuar Leyendo

A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object —a starless, gas-rich, dark-matter cloud that is considered a “relic” or remnant of early galaxy formation. Nicknamed “Cloud-9,” this is the first confirmed detection of such an object in the Universe. The finding furthersContinuar Leyendo

Data acquired with multiple NSF NOIRLab facilities indicate gamma-ray burst lasting over seven hours resides in a massive, extremely dusty galaxy. Astronomers have observed the longest-ever gamma-ray burst — a powerful, extragalactic explosion that lasted over seven hours. Rapid follow-up observations with the U.S. Department of Energy-fabricated Dark Energy CameraContinuar Leyendo
