N44是一个复杂的星云，充满了发光的氢气、黑暗的尘埃带、大质量恒星和许多不同年龄的恒星群。然而，它最显着的特征之一是被称为“超级气泡”的黑暗星空间隙，在这张哈勃太空望远镜图像中上部中央区域可见。 这个黑洞大约有250光年宽，它的存在仍然是一个谜。气泡内部的大质量恒星喷出的恒星风可能赶走了气体，但这与测量到的气泡中的风速不一致。另一种可能性是，由于星云中充满了大质量恒星，这些恒星会在巨大的爆炸中消亡，古老超新星不断膨胀的外壳塑造了宇宙洞穴。 天文学家在超级气泡附近发现了一颗超新星遗迹，并确定超级气泡内部和边缘的恒星之间存在大约 500 万年的年龄差异，表明存在多个连锁反应的恒星形成事件。超级气泡 […]
The Hubble Space Telescope’s glamour shots of the universe nearly always have a discovery behind them. 哈勃太空望远镜拍摄的迷人的宇宙照片背后几乎都有一个发现。 In this image, a remote galaxy is greatly magnified and distorted by the effects of gravitationally warped space. After its public release, astronomers used the p
This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91. Their delicate galactic dance takes place more than 100 million light-years from Earth. The two galaxies comprising Arp 91 have their own names: the lower galax

Britt This comparison of two images shows puffing dust bubbles and an erupting gas shell – the final acts of a monster star’s life. 这两张图片的对比显示了膨胀的尘埃气泡和喷发的气体外壳——这是一颗巨型恒星生命的最后一幕。 These new views showcase the dual nature of the star AG Carinae, which was the ta
On Women’s Equality Day, NASA celebrates the women who are breaking barriers and paving the way for future generations. In this image, Dr. Nancy Grace Roman (1925-2018), NASA’s first Chief of Astronomy and “the Mother of Hubble,” visits the Space Telescope Operations Control Center

天文学家首次在木星的卫星木卫三的大气中发现了水蒸气的证据。这种水蒸气是在木卫三表面的冰升华时形成的，也就是说，从固体变成气体。 科学家们利用NASA哈勃太空望远镜新的档案数据集，做出了这一发现，发表在《自然天文学》杂志上。 这张照片展示了1996年NASA哈勃太空望远镜观测到的木星卫星木卫三。木卫三位于5亿英里(超过6亿公里)之外，哈勃可以跟踪卫星上的变化，并在紫外和近红外波长揭示其他特征。天文学家现在利用哈勃望远镜提供的新的档案数据集，首次揭示了木星卫星木卫三大气中存在水蒸气的证据，这是由于水蒸气从卫星的冰面热逸出而来。 影像来源：NASA, ESA, John Spencer (SwRI
Two enormous galaxies capture your attention in this spectacular image taken with the NASA/ESA Hubble Space Telescope using the Wide Field Camera 3 (WFC3). The galaxy on the left is a lenticular galaxy, named 2MASX J03193743+4137580. The side-on spiral galaxy on the right is more simply named UGC 26
This image taken with the NASA/ESA Hubble Space Telescope depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic Cloud. The cluster – which is in the constellation Tucana (the Toucan) – contains a multitude of stars, many of which are scattered
