2023年9月7日 The Large Cloud of Magellan Image Credit & Copyright: Chris Willocks Explanation: The 16th century Portuguese navigator Ferdinand Magellan and his crew had plenty of time to study the southern sky during the first circumnavigation of planet Earth. As a result, two fuzzy cloud-like objects easily visible to southern hemisphere skygazers are known as the Clouds of Magellan, now understood to be satellite galaxies of our much larger, spiral Milky Way galaxy. About 160,000 light-years distant in the constellation Dorado, the Large Magellanic Cloud is seen in this sharp galaxy portrait. Spanning about 15,000 light-years or so, it is the most massive of the Milky Way’s satellite galaxies and is the home of the closest supernova in modern times, SN 1987A. The prominent patch…

2023年4月27日 The Tarantula Nebula from SuperBIT Image Credit: SuperBIT, NASA Explanation: The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 160 thousand light-years away, it’s the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid is near the center of this spectacular image taken during the flight of SuperBIT (Super Pressure Balloon Imaging Telescope), NASA’s balloon-borne 0.5 meter telescope now floating near the edge of space. Within the well-studied Tarantula (NGC 2070), intense radiation, stellar winds and supernova shocks from the central young cluster of massive stars, cataloged as R136, energize the nebular glow and shape…

2022年9月16日 The Tarantula Zone Image Credit & Copyright: >Processing – Robert Gendler, Roberto Colombari Data – Hubble Tarantula Treasury, European Southern Observatory, James Webb Space Telescope, Amateur Sources Explanation: The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 180 thousand light-years away, it’s the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid sprawls across this magnificent view, an assembly of image data from large space- and ground-based telescopes. Within the Tarantula (NGC 2070), intense radiation, stellar winds, and supernova shocks from the central young cluster of massive stars cataloged as R136 energize the nebular glow…

2022年9月7日 Tarantula Stars R136 from Webb Images Credit & Copyright: NASA, ESA, CSA, STScI, Webb ERO Production Team Explanation: Near the center of a nearby star-forming region lies a massive cluster containing some of the largest and hottest stars known. Collectively known as star cluster NGC 2070, these stars are part of the vast Tarantula Nebula and were captured in two kinds of infrared light by the new Webb Space Telescope. The main image shows the group of stars at NGC 2070’s center — known as R136 — in near-infrared, light just a bit too red for humans to see. In contrast, the rollover image captures the cluster center in mid-infrared light, light closer to radio waves. Since R136’s brightest stars emit more of their…

2020年11月13日 The Tarantula Zone Image Credit & Copyright: Ignacio Diaz Bobillo Explanation: The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 180 thousand light-years away, it’s the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid sprawls across the top of this spectacular view, composed with narrowband filter data centered on emission from ionized hydrogen and oxygen atoms. Within the Tarantula (NGC 2070), intense radiation, stellar winds and supernova shocks from the central young cluster of massive stars, cataloged as R136, energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star…
