A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy. This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed ...

2016年1月14日 · Astronomers have glimpsed the most powerful supernova ever seen, a star in a galaxy billions of light-years away that exploded with such force it briefly shone nearly 600 billion times brighter...

2023年5月19日 · The stellar explosion, AT2021lwx, took place about 8 billion light-years away in the constellation Vulpecula and was over ten times brighter than any supernova ever observed and 100 times...

2020年4月13日 · A blast about 4.5 million light-years away has released about 10 times more energy than the sun will emit in its entire lifetime, making it the most powerful supernova ever spotted.

2020年4月15日 · Scientists have observed the biggest supernova — stellar explosion — ever detected, the violent death of a huge star up to 100 times more massive than our sun in a faraway galaxy.

2020年4月13日 · First discovered at Hawaii's Panoramic Survey Telescope and Rapid Response System observatory in 2016, scientists have spent the past several years studying the event, dubbed SN2016aps. It is perhaps the largest supernova ever seen, a …

2020年4月15日 · Astronomers have spotted a record-breaking supernova — the largest ever observed. The spectacular stellar explosion released enough light to cover its entire galaxy, outshining normal...

2025年1月14日 · "Studying distant supernova explosions is the only way to explore the individual stars that populate these early galaxies," team member and University of Arizona in Tucson researcher Christa ...

2024年1月14日 · Scientists ultimately used 1,499 type Ia supernovae with high-quality data, making it the largest, deepest supernova sample from a single telescope ever compiled. In 1998, the Nobel-winning astronomers used just 52 supernovae to determine that the universe is expanding at an accelerating rate. “It’s a really massive scale-up from 25 years ...

2025年1月31日 · The subject of this NASA/ESA Hubble Space Telescope image is a supernova-hosting galaxy located about 600 million light-years away in the constellation Gemini. Hubble captured this image roughly two months after a supernova named SN 2022aajn was discovered. The supernova is visible as a blue dot at the center of …
