2022年5月23日 The Once and Future Stars of Andromeda Image Credit: NASA, NSF, NOAJ, Hubble, Subaru, Mayall, DSS, Spitzer; Processing & Copyright: Robert Gendler & Russell Croman Explanation: This picture of Andromeda shows not only where stars are now, but where stars will soon be. Of course, the big, beautiful Andromeda Galaxy, M31, is a spiral galax...
2022年5月12日 Young Stars of NGC 346 Image Credit: NASA, ESA – acknowledgement: Antonella Nota (ESA/STScI) et al., Explanation: The massive stars of NGC 346 are short lived, but very energetic. The star cluster is embedded in the largest star forming region in the Small Magellanic Cloud, some 210,000 light-years distant. Their winds and radiation sweep ou...
2022年5月6日 NGC 3572 and the Southern Tadpoles Image Credit & Copyright: Carlos Taylor Explanation: This cosmic skyscape features glowing gas and dark dust clouds along side the young stars of NGC 3572. A beautiful emission nebula and star cluster it sails far southern skies within the nautical constellation Carina. Stars from NGC 3572 are toward top cent...
2022年3月18日 A Filament in Monoceros Image Credit & Copyright: Giorgio Ferrari Explanation: Bluish reflection nebulae seem to fill this dusty expanse. The sharp telescopic frame spans over 1 degree on the sky toward the faint but fanciful constellation Monoceros, the Unicorn. Seen within the Monoceros R1 cloud complex some 2,500 light-years away, bluish I...
2022年3月14日 Star Formation in the Eagle Nebula Image Credit: NASA, ESA, Hubble; Processing & Copyright: Ignacio Diaz Bobillo & Diego Gravinese Explanation: Where do stars form? One place, star forming regions known as “EGGs”, are being uncovered at the end of this giant pillar of gas and dust in the Eagle Nebula (M16). Short for evaporat...
2022年2月17日 Chamaeleon I Molecular Cloud Image Credit & Copyright: Acquisition: Stas Volskiy (Chilescope.com), Processing: Robert Eder Explanation: Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and active star formation. They lie a mere 650 light-years away, at the boundary of the local bubble and...
2022年2月10日 T Tauri and Hind’s Variable Nebula Image Credit & Copyright: Dawn Lowry, Gian Lorenzo Ferretti, Ewa Pasiak and Terry Felty Explanation: The star with an orange tint near top center in this dusty telescopic frame is T Tauri, prototype of the class of T Tauri variable stars. Next to it (right) is a yellow cosmic cloud historically known a...
2022年1月31日 Carina Nebula North Image Credit & Copyright: Roberto Colombari Explanation: The Great Carina Nebula is home to strange stars and iconic nebulas. Named for its home constellation, the huge star-forming region is larger and brighter than the Great Orion Nebula but less well known because it is so far south — and because so much of humani...
2022年1月27日 South of Orion Image Credit & Copyright: Vikas Chander Explanation: South of the large star-forming region known as the Orion Nebula, lies bright blue reflection nebula NGC 1999. At the edge of the Orion molecular cloud complex some 1,500 light-years distant, NGC 1999’s illumination is provided by the embedded variable star V380 Orionis...
2022年1月21日 Young Star Jet MHO 2147 Image Credit & License: International Gemini Observatory / NOIRLab / NSF / AURA Acknowledgments: L. Ferrero (Universidad Nacional de Córdoba) Explanation: Laser guide stars and adaptive optics sharpened this stunning ground-based image of stellar jets from the Gemini South Observatory, Chilean Andes, planet Earth. Thes...
