Astronomers have confirmed Elias 2-24 b, a Jupiter-mass exoplanet less than a million years old and still forming inside its star’s gas-and-dust disk. Its confirmation came from combining archival observations from the Keck Observatory with earlier observations from ALMA and the Very Large Telescope.

Astronomers found 84 unusually low-energy X-ray sources in six galaxies by searching publicly available Chandra data. Their physical nature remains unknown, but they may involve accreting black holes, neutron stars or white dwarfs.

Coordinated Hubble and Webb observations of 27 faint trans-Neptunian objects found that small bodies show colour relationships linked to their dynamical populations, while their numbers were lower than some planet-formation models predicted.
