This NASA/ESA Hubble Space Telescope observation has captured the galaxy CGCG 396-2, an unusual multi-armed galaxy merger which lies around 520 million light-years from Earth in the constellation Orion. This observation is a gem from the Galaxy Zoo project, a citizen science project involving hundre […]
The Hubble Space Telescope captured this glittering scene using its Wide Field Camera 3 and Advanced Camera for Surveys. Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars. As this image demonstrates, the hearts of globular clusters are densely packed with s
The brilliant cascade of stars through the middle of this image is the galaxy ESO 318-13 as seen by the Hubble Space Telescope in this image from 2012. Despite being located millions of light-years from Earth, the stars captured in this image are so bright and clear one could almost attempt to count
2022年6月15日 In the Heart of the Virgo Cluster Image Credit & Copyright: Saulius Adomaitis Explanation: The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy. The Virgo Cluster is so close that it spans more than 5 degrees on the sky – about 10 times the a
2022年6月11日 The Road and the Milky Way Image Credit & Copyright: David Cruz Explanation: At night you can follow this road as it passes through the Dark Sky Alqueva reserve not too far from Alentejo, Portugal. Or you could stop, look up, and follow the Milky Way through the sky. Both stretch fro
2022年6月10日 Arp 286: Trio in Virgo Image Credit & Copyright: Nicolas Rolland, Telescope.Live Explanation: This colorful telescopic field of view features a trio of interacting galaxies almost 90 million light-years away, toward the constellation Virgo. On the right two spiky, foreground Milky Wa
This new image from NASA’s Hubble Space Telescope looks at two spiral galaxies, collectively known as Arp 303. The pair, individually called IC 563 (bottom right) and IC 564 (top left), are 275 million light-years away in the direction of the constellation Sextans. The image holds data from two sepa
NASA的哈勃太空望远镜完成了近30年的马拉松比赛，校准了40多个时空“里程碑”，以帮助科学家精确测量宇宙的膨胀率——这是一项曲折的探索。 这组来自NASA哈勃太空望远镜的 36 幅图像展示了这些特征星系，它们都是造父变星和超新星的宿主。 这两种天体现象都是天文学家用来确定天文距离的重要工具，并已被用于改进我们对哈勃常数（宇宙膨胀率）的测量。 这张照片中显示的星系（从顶行，左行到底行，右行）是：NGC 7541，NGC 3021，NGC 5643，NGC 3254，NGC 3147，NGC 105，NGC 2608，NGC 3583，NGC 3147，Mrk 1337，NGC 5861，NGC
This new NASA Hubble Space Telescope image captures the central region of the gigantic elliptical galaxy NGC 474. Located some 100 million light-years from Earth, NGC 474 spans about 250,000 light-years across – that’s 2.5 times larger than our own Milky Way galaxy! Along with its enormous size, NGC
This new NASA Hubble Space Telescope image spotlights the giant elliptical galaxy, UGC 10143, at the heart of galaxy cluster, Abell 2147, about 486 million light-years away in the head of the serpent, the constellation Serpens. UGC 10143 is the biggest and brightest member of Abell 2147, which itsel
