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....
2020 July 3 Lynds Dark Nebula 1251 Image Credit & Copyright: Ara Jerahian Explanation: Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomic...
2020 June 18 The Tadpoles of IC 410 Image Credit & Copyright: Trevor Jones Explanation: This telescopic close-up shows off the central regions of otherwise faint emission nebula IC 410, captured under backyard suburban skies with narrowband filters. It also features two remarkable inhabitants of the cosmic pond of gas and dust. Below and right of center...
2020 April 20 IC 2944: The Running Chicken Nebula Image Credit & Copyright: Juan Filas Explanation: To some, it looks like a giant chicken running across the sky. To others, it looks like a gaseous nebula where star formation takes place. Cataloged as IC 2944, the Running Chicken Nebula spans about 100 light years and lies about 6,000 light years away t...
