Light and neutrinos from the explosion reached Earth on February 23, 1987, and it was designated "SN 1987A" as the first supernova discovered that year. Its brightness peaked in May of that year, with an …

This video shows a visualization of SN 1987A and the evolution of the resulting supernova remnant up until the present day. The visualization begins by showing the progenitor star surrounded by a ring of …

Feb 24, 2017 · Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. The titanic supernova, called Supernova 1987A (SN 1987A), blazed with the power …

Once upon a time, about 11 million years ago, in a galaxy not so far away (the LMC), the progenitor star of supernova 1987a was born, Sanduleak -69° 202 with a mass about 18 times that of our sun.

Aug 31, 2023 · 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, …

Supernova 1987A, first supernova observed in 1987 (hence its designation) and the nearest to Earth in more than three centuries. It occurred in the Large Magellanic Cloud, a satellite galaxy of the Milky …

Supernova 1987A, the first supernova observed in 1987, was the brightest and nearest supernova to Earth in almost four centuries. Before it exploded, it was a luminous blue giant star that put out …

Feb 22, 2024 · When a nearby star exploded in 1987, it created the first supernova visible to the naked eye in 4 centuries and became one of the most intensely studied objects in space. Now, after more …

Feb 22, 2024 · 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 …

4 days ago · This absence dramatically strengthens the case that the three neutrino masses really can be found from the SN 1987A data, and it suggests a way KATRIN can redo its analysis that may …
