SN 1987A was a type II supernova in the Large Magellanic Cloud, a dwarf satellite galaxy of the Milky Way. It occurred approximately 51.4 kiloparsecs (168,000 light-years) [a] from Earth and was the closest observed supernova since Kepler's Supernova in 1604.

2017年2月24日 · The titanic supernova, called Supernova 1987A (SN 1987A), blazed with the power of 100 million suns for several months following its discovery on Feb. 23, 1987. Since that first sighting, SN 1987A has continued to fascinate astronomers with its spectacular light show.

2023年8月31日 · NASA’s James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987.

2017年2月24日 · Supernova 1987A: A supernova in the Large Magellanic Cloud about 160,000 light years from Earth. Thirty years have passed since Supernova 1987A was first seen. Since then, telescopes around the world and in space have observed this …

2024年2月22日 · NASA’s James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole.

2024年10月22日 · This image, released on Feb. 24, 2017, shows Supernova 1987a (center) surrounded by dramatic red clouds of gas and dust within the Large Magellanic Cloud. This supernova, first discovered on Feb. 23, 1987, blazed with the power of 100 million Suns.

On February 23, 1987, astronomers noticed a new source of light in the Large Magellanic Cloud (LMC), a small satellite galaxy of the Milky Way. Soon, scientists realized that this new beacon was, in fact, a spectacular explosion caused by the death of a massive star. It was a supernova. The Large Magellanic Cloud in optical light.

2023年8月31日 · Webb’s NIRCam (Near-Infrared Camera) captured this detailed image of SN 1987A (Supernova 1987A). At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb.

2017年2月24日 · Thirty years ago on February 24, 1987, observers in the southern hemisphere noticed a new object in the Large Magellanic Cloud. Today, we know this object as Supernova 1987A, and it was one of the brightest supernova seen in hundreds of years.

2025年3月2日 · SN 1987A位于大麦哲伦星系中，距离地球168,000光年，首次于1987年2月被观测到，这是自400多年前克卜勒目击超新星之后第一颗肉眼观测到的超新星，近40年来一直是伽马射线到无线电波波段范围的重点观测目标，现在韦伯太空望远镜也开始加入观测的行列，透过近 ...
