分子云分子云molecularcloud星际分子集结的区域。观测表明,虽然有些星际分子,如CO,几乎散布在所有的天区,但大多数星际分子集结成团,形成分子云。分子云通常是暗的,在光学波段看不见,温度典型值为20K,平均密度102~104个分子厘米3,中央的密度可达106个分子厘米3,质量一般为104~107太阳质量,云内有足够的尘埃屏蔽星光中的紫外线,使分子免遭破坏。在猎户星云后面有一个巨大的分子云,它是离太阳最近的分子云之一,由小而密的核心以及延伸的低密度云两部分组成。前者的直径为0.15秒差距,密度为105个分子厘米3,质量为5个太阳质量;后者的直径至少为10秒差距,极大密度为103个分子厘米3,质量达104太阳质量。被认为是正在形成的恒星的BN天体就在猎户分子云中间,BN天体附近还有另一个红外源,可能也包括年轻恒星或者正在形成中的恒星。
