2023年10月11日 NGC 1097: Spiral Galaxy with Supernova Image Data: Telescope Live (Chile); Image Processing & Copyright: Bernard Miller Explanation: What’s happening in the lower arm of this spiral galaxy? A supernova. Last month, supernova SN 2023rve was discovered with UAE‘s Al-Khatim Observatory and later found to be consistent with the death explosion of a massive star, possibly leaving behind a black hole. Spiral galaxy NGC 1097 is a relatively close 45 million light years away and visible with a small telescope toward the southern constellation of the Furnace (Fornax). The galaxy is notable not only for its picturesque spiral arms, but also for faint jets consistent with ancient star streams left over from a galactic collision — possibly with the small galaxy seen between its…
NASA的詹姆斯·韦伯太空望远镜已经开始研究最著名的超新星之一SN 1987A（超新星1987A）。SN 1987A位于16.8万光年之外的大麦哲伦星云中，自1987年2月被发现以来，近40年来一直是从伽马射线到无线电波长的密集观测目标。
2023年8月6日 SN 1006: A Supernova Ribbon from Hubble Credit: NASA, ESA, Hubble Heritage (STScI/AURA); Acknowledgement: W. Blair et al. (JHU) Explanation: What created this unusual space ribbon? The answer: one of the most violent explosions ever witnessed by ancient humans. Back in the year 1006 AD, light reached Earth from a stellar explosion in the constellation of the Wolf (Lupus), creating a “guest star” in the sky that appeared brighter than Venus and lasted for over two years. The supernova, now cataloged at SN 1006, occurred about 7,000 light years away and has left a large remnant that continues to expand and fade today. Pictured here is a small part of that expanding supernova remnant dominated by a thin and outwardly moving shock front that…
2023年7月9日 Doomed Star Eta Carinae Image Credit & Copyright: NASA, ESA, Hubble; Processing & License: Judy Schmidt Explanation: Eta Carinae may be about to explode. But no one knows when – it may be next year, it may be one million years from now. Eta Carinae‘s mass – about 100 times greater than our Sun – makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural LASER light. This featured image brings out details in the unusual nebula that surrounds this rogue star….
