#star formation

حدد باحثون باستخدام ALMA حلقة غازية دافئة بعرض نحو 1000 وحدة فلكية حول نجم أولي مطمور بعمق في الثور، مضيفين قطعة جديدة إلى لغز كيف تتخلص النجوم الرضيعة من الطاقة وتواصل النمو

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,

New James Webb Space Telescope observations of W51 are exposing previously hidden young stars and the gas-and-dust structures around them in unusually fine detail.

Astronomers have directly measured superheated gas blasting out of the starburst galaxy M82 at more than 3.2 million kilometers per hour, strengthening the case for a stellar-driven outflow.

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.
