M15: 紧实的球状星团

2023年6月15日 M15: Dense Globular Star Cluster Image Credit: NASA, ESA, Hubble Legacy Archive; Processing: Ehsan Ebrahimian Explanation: Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it’s one of about 170 globular star clusters that still roam the halo of the Milky Way. Centere...

在钱德拉的图像中,“H”代表炽热和巨大

在梅西耶84星系(M84)的热气中有一个“H”形结构。来自银河系中心超大质量黑洞的喷流在高温下产生了相反方向的空洞。NASA钱德拉X射线天文台的X射线数据(以粉红色显示)与VLA的无线电数据(以蓝色显示)相结合,显示了这一点。

星系、喷流与著名的黑洞

2023年5月4日 The Galaxy, the Jet, and a Famous Black Hole Image Credit: NASA, JPL-Caltech, Event Horizon Telescope Collaboration Explanation: Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth’s Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster ...

哈勃太空望远镜拍摄到异常明亮的相互作用星系

This new image from NASA’s Hubble Space Telescope shows interacting galaxies known as AM 1214-255. These galaxies contain active galactic nuclei, or AGNs. An AGN is an extraordinarily luminous central region of a galaxy. Its extreme brightness is caused by matter whirling into a supermassive black hole at the galaxy’s heart. Hubble observed the galaxy closes...

中子星碰撞

Two neutron stars begin to merge in this illustration, blasting a jet of high-speed particles and producing a cloud of debris. These gamma-ray bursts (GRBs) are the most powerful events in the universe. Scientists think these kinds of events are factories for a significant portion of the universe’s heavy elements, including gold. They based their estimates o...

NASA的钱德拉在碰撞过程中发现了巨大的黑洞

正如我们最新的新闻稿中所讨论的那样,使用NASA钱德拉X射线天文台的一项新研究跟踪了矮星系碰撞过程中的两对超大质量黑洞。这是这种即将发生的碰撞的第一个证据,为科学家提供了关于宇宙早期黑洞生长的重要信息。 根据定义,矮星系包含的恒星的总质量小于30亿个太阳,大约是银河系的20倍。天文学家长期以来一直怀疑,矮星系合并,特别是在相对早期的宇宙中,是为了成长为今天所见的更大的星系。然而,目前的技术无法观测到第一代矮星系合并,因为它们在遥远的距离上非常微弱。另一种策略(寻找更近距离的矮星系合并)迄今尚未成功。 这项新研究克服了这些挑战,对钱德拉X射线观测进行了系统的调查,并将其与NASA广域红外线巡天望远镜(WISE)的红外数据和加拿大-法国-夏威夷望远镜(CFHT)的光学数据进行了比较。 钱德拉在这项研究中特别有价值,...

韦伯图像: 棒旋星系NGC 1365

2023年2月18日 Barred Spiral Galaxy NGC 1365 from Webb Image Credit: NASA, ESA, CSA, Janice Lee (NOIRLab) – Processing: Alyssa Pagan (STScI) Explanation: A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That’s twice the size of our own b...
