A small, dense cloud of gas and dust called CB 130-3 blots out the center of this image from the NASA/ESA Hubble Space Telescope. CB 130-3 is an object known as a dense core, a compact agglomeration of gas and dust. This particular dense core is in the constellation Serpens and seems to billow across a field of background stars. Dense cores like CB 130-3 are...
This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1,350 light-years from Earth and lies near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation – it is composed of debris left over from...
在NASA詹姆斯·韦伯太空望远镜的近红外视图中,创生之柱呈现出万花筒般的色彩。这些柱子看起来像是从沙漠景观中升起的拱门和尖塔,但却充满了半透明的气体和尘埃,而且不断变化。这是一个年轻恒星正在形成的区域,或者说,在它们继续形成的过程中刚刚从它们的尘埃茧中破茧而出。 影像来源:NASA, ESA, CSA, STScI; Joseph DePasquale (STScI), Anton M. Koekemoer (STScI), Alyssa Pagan (STScI). NASA的詹姆斯·韦伯太空望远镜拍摄到了一幅郁郁葱葱、非常详细的景观——标志性的创生之柱,在那里,新的恒星正在稠密的气体云和尘埃云中形成。这些三维柱子看起来像雄伟的岩层,但渗透性更强。这些柱状物由冷的星际气体和尘埃组成,它们有时在近红外光下呈半透...
