Life’s Ingredients Found Around Baby Star! Astronomers found 17 complex organic molecules like ethylene glycol & glycolonitrile, around the young star V883 Orionis. These prebiotic compounds, detected by ALMA, are vital for forming amino acids and DNA bases. The findings
天文学家利用阿塔卡马大型毫米/亚毫米阵列（ALMA）望远镜，对年轻恒星V883猎户座周围的原行星盘进行了观测，发现了多种复杂有机分子，包括甲醇、乙醛、丙酮等。这些分子在恒星爆发期间从冰中升华为气体，表明原行星盘中存在丰富的有机物质。
V883猎户座是一颗正在经历增光的年轻恒星，周围环绕着气体和尘埃构成的原行星盘。研究人员通过ALMA的观测，发现这些复杂有机分子在恒星增光期间从冰中升华为气体，释放到盘中。这一发现为研究原行星盘中有机分子的组成和分布提供了重要线索。
这些发现有助于我们理解恒星和行星形成过程中有机分子的形成和演化过程，以及它们在宇宙中分布的机制。

ALMA Observatory
This image shows the first "astrosphere" surrounding a Sun-like star younger than our Sun. This new discovery gives us a chance to study the structure our own Sun may have been embedded in several billion years ago. More at: s.si.edu/astrosphere ⭐
The Invisible Heart of the Galaxy The ALMA observatory in Chile's Atacama Desert has captured its largest image ever—and it reveals the center of the Milky Way. A region more than 650 light-years across around a supermassive black hole, woven through by filaments of cosmic gas.
