Webb Telescope Reveals Dust-Rich Water Ice in Interstellar Comet 3I/ATLAS

NASA/ESA/CSA's James Webb Space Telescope analyzed the third confirmed interstellar comet, finding water ice mixed with dark rocky material. High deuterium levels suggest formation in extremely cold conditions ~10–12 billion years ago in a metal-poor environment, unlike Solar System comets.

Webb identified the host galaxy of the most distant fast radio burst yet

NASA says the James Webb Space Telescope found an actively star-forming dwarf galaxy 1,000 times less massive than expected.

$A field full of small galaxies of all shapes against the blackness of space. A few bright white stars show 8 prominent diffraction spikes. A small galaxy at lower right is highlighted with a white box. A shaded triangle extends upward to the corners of a larger box showing a zoom in of the region. Two fuzzy, light blue blobs are at center, with a larger and brighter one at top. Just above the top blob is a white crosshair showing the location where a fast radio burst was detected.$

Bennu's parent body probably formed near the solar system's water-ice line

ETH Zurich says new sample analyses suggest Bennu's parent body emerged in a transition zone cold enough for water to freeze, while Jupiter was still growing.

Black holes of vastly different masses reportedly launch jets at the same feeding stage

The Institute for Advanced Study says an international collaboration co-led by one of its scholars found a universal rule governing when stellar-mass and supermassive black holes launch powerful jets.
