#ALMA

De nouvelles observations d’ALMA ont détecté de l’eau deutérée dans 3I/ATLAS, offrant aux astronomes leur première lecture chimique sur l’origine d’un objet interstellaire et pointant vers un environnement plus froid et moins irradié que celui du jeune Système solaire.

Researchers using ALMA have identified a warm gas ring about 1,000 astronomical units across around a deeply embedded protostar in Taurus, adding a new piece to the puzzle of how infant stars shed energy and keep growing

New James Webb observations of the Milky Way’s W51 region are exposing young stars and intricate structures previously obscured by dust, while comparisons with ALMA also show how much of star formation still remains ve,

Astronomers using the ALMA telescope have produced the largest image ever taken of the Milky Way's central region, spanning 650 light-years. The mosaic reveals a complex network of cold gas filaments and dozens of molecules, from simple silicon compounds to complex organics like acetone and ethanol.

A massive international collaboration using the James Webb Space Telescope and ALMA has identified 70 dusty galaxies from the universe's first billion years. These ancient objects appear to have formed stars far earlier than current models predict, potentially forcing a fundamental reassessment of how galaxies evolve.
