2022年11月18日 The Protostar within L1527 Image Credit: Science – NASA, ESA, CSA, STScI, NIRCam Processing – Joseph DePasquale (STScI), Anton M. Koekemoer (STScI), Alyssa Pagan (STScI) Explanation: The protostar within dark cloud L1527 is a mere 100,000 years old, still embedded in the cloud of gas and dust that feeds its growth. In this NIRCam imag...
2022年7月24日 Saturn in Infrared from Cassini Image Credit: NASA, JPL-Caltech, SSI; Processing: Maksim Kakitsev Explanation: Many details of Saturn appear clearly in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn’s North Pole....
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...
2021年11月19日 NGC 281: Starless with Stars Image Credit & Copyright: Wido Oerlemans – X-ray: Chandra, Infrared: Spitzer Explanation: In visible light the stars have been removed from this narrow-band image of NGC 281, a star forming region some 10,000 light-years away toward the constellation Cassiopeia. Stars were digitally added back to the result...

2021年04月19日 The Galactic Center in Infrared Image Credit: NASA, JPL-Caltech, Spitzer Space Telescope, Susan Stolovy (SSC/Caltech) et al.; Reprocessing: Judy Schmidt Explanation: What does the center of our galaxy look like? In visible light, the Milky Way’s center is hidden by clouds of obscuring dust and gas. But in this stunning vista, the Spitzer Sp...
2021年04月17日 Inside the Flame Nebula Image Credit: NASA, JPL-Caltech, IPAC Infrared Science Archive – Processing: Amal Biju Explanation: The Flame Nebula is a stand out in optical images of the dusty, crowded star forming regions toward Orion’s belt and the easternmost belt star Alnitak, a mere 1,400 light-years away. Alnitak is the bright star at...
2021年03月19日 Central Lagoon in Infrared Image Credit & License: NASA, ESA, Hubble; Data Archive: MAST, Processing: Alexandra Nachman Explanation: Stars fill this infrared view, spanning 4 light-years across the center of the Lagoon Nebula. Visible light images show the glowing gas and obscuring dust clouds that dominate the scene. But this infrared image...
2021年03月07日 Pillars of the Eagle Nebula in Infrared Image Credit: NASA, ESA, Hubble, HLA; Processing: Luis Romero Explanation: Newborn stars are forming in the Eagle Nebula. Gravitationally contracting in pillars of dense gas and dust, the intense radiation of these newly-formed bright stars is causing surrounding material to boil away. This image, taken wit...
