2020年12月06日 M16: Pillars of Star Creation Image Credit: NASA, ESA, Hubble Space Telescope, J. Hester, P. Scowen (ASU) Explanation: These dark pillars may look destructive, but they are creating stars. This pillar-capturing image of the inside of the Eagle Nebula, taken with the Hubble Space Telescope in 1995, shows evaporating gaseous globules (EGGs) emergin...
2020年12月01日 NGC 346: Star Forming Cluster in the SMC Image Credit & License: NASA, ESA, Hubble; Processing: Judy Schmidt Explanation: Are stars still forming in the Milky Way’s satellite galaxies? Found among the Small Magellanic Cloud’s (SMC’s) clusters and nebulas, NGC 346 is a star forming region about 200 light-years across, pictur...
2020年11月28日 NGC 6822: Barnard’s Galaxy Image Credit & Copyright: Data – Martin Pugh, Processing – Mark Hanson Explanation: Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small galaxies form stars too, like nearby NGC 6822, also known as B...
2020年11月10日 The Central Soul Nebula Without Stars Image Credit & Copyright: Jason Guenzel Explanation: This cosmic close-up looks deep inside the Soul Nebula. The dark and brooding dust clouds near the top, outlined by bright ridges of glowing gas, are cataloged as IC 1871. About 25 light-years across, the telescopic field of view spans only a small par...
2020年11月01日 In the Center of the Trifid Nebula Image Credit: Subaru Telescope (NAOJ), Hubble Space Telescope, Martin Pugh; Processing: Robert Gendler Explanation: What’s happening at the center of the Trifid Nebula? Three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear near the bottom, while other d...
2020年10月28日 NGC 6357: The Lobster Nebula Image Credit & Copyright: Steven Mohr Explanation: Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center — a home to unusually bright and massive stars. The overall blue glo...
2020年10月4日 Orion Nebula in Oxygen, Hydrogen, and Sulfur Image Credit & Copyright: César Blanco González Explanation: Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula. The Nebula’s glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud. Many of the filamen...
2020年8月7日 The Pipe Nebula Image Credit & Copyright: Jose Mtanos Explanation: East of Antares, dark markings sprawl through crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds include B59, B72, B77 and B78, seen in against the starry backgro...
2020年8月1日 The Elephant’s Trunk Nebula in Cepheus Image Credit & Copyright: Chad Leader Explanation: Like an illustration in a galactic Just So Story, the Elephant’s Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, the cosmic elephan...
2020年7月28日 NGC 6188: The Dragons of Ara Image Credit & Copyright: Ariel L. Cappelletti Explanation: Dark shapes with bright edges winging their way through dusty NGC 6188 are tens of light-years long. The emission nebula is found near the edge of an otherwise dark and large molecular cloud in the southern constellation Ara, about 4,000 light-years away....
