2023年4月22日 NGC 1333: Stellar Nursery in Perseus Image Credit: Science – NASA, ESA, STScI, Processing – Varun Bajaj (STScI), Joseph DePasquale (STScI), Jennifer Mack (STScI) Explanation: In visible light NGC 1333 is seen as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-...
2023年4月20日 The Dark Seahorse in Cepheus Image Credit & Copyright: Jeff Herman Explanation: Spanning light-years, this suggestive shape known as the Seahorse Nebula appears in silhouette against a rich, luminous background of stars. Seen toward the royal northern constellation of Cepheus, the dusty, obscuring clouds are part of a Milky Way molecular clou...
2023年4月10日 IC 2944: The Running Chicken Nebula Image Credit & Copyright: Daniel Stern 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 to...
2023年3月21日 Dark Nebulae and Star Formation in Taurus Image Credit & Copyright: Vikas Chander Explanation: Can dust be beautiful? Yes, and it can also be useful. The Taurus molecular cloud has several bright stars, but it is the dark dust that really draws attention. The pervasive dust has waves and ripples and makes picturesque dust bunnies, but perhaps...
2023年2月4日 NGC 2626 along the Vela Molecular Ridge Image Credit & Copyright: Mike Selby & Mark Hanson Explanation: Centered in this colorful cosmic canvas, NGC 2626 is a beautiful, bright, blue reflection nebula in the southern Milky Way. Next to an obscuring dust cloud and surrounded by reddish hydrogen emission from large H II region RCW 27 it lie...

Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA) Processing – Alyssa Pagan (STScI), Nolan Habel (USRA), Laura Lenkić (USRA), Laurie E. U. Chu (NASA Ames) Explanation: The most massive young star cluster in the Small Magellanic Cloud is NGC 346,...
2023年1月10日 NGC 2264: The Cone Nebula Image Credit & Copyright: Matthew Dieterich Explanation: Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where clouds of gas and dust are sculpted by energetic winds from newborn stars. The Cone Nebula, a well-known example,...
2022年12月6日 M16: A Star Forming Pillar from Webb Image Credit: NASA, ESA, CSA, STScI, Processing & Copyright: Mehmet Hakan Özsaraç Explanation: What’s happening inside this interstellar mountain? Stars are forming. The mountain is actually a column of gas and dust in the picturesque Eagle Nebula (M16). A pillar like this is so low in density that you cou...
2022年11月25日 NGC 6744: Extragalactic Close-Up Image Credit: NASA, ESA, and the LEGUS team Explanation: Beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across. That’s larger than the Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo, with its galactic disk tilted towards our line of sight. This Hubbl...
2022年11月24日 Lynds Dark Nebula 1251 Image Credit & Copyright: Stefano Attalienti 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, astr...
