[–] sradman 5y ago ↗ The paper NS 1987A in SN 1987A [1] claims that Super Nova SN 1987A most likely created a Neutron Star (NS 1987A):> The suspected detection stems from an excess of infrared emission from a dust blob near the compact object’s predicted position.[1] https://arxiv.org/pdf/2004.06078.pdf
[–] johnr2 5y ago ↗ > A Star Went Supernova in 1987It didn't go supernova in 1987. It happened around 168,000 years before that, but it took the light from the event that long to reach us. A better title might be "A supernova was observed in 1987".

It didn't go supernova in 1987. It happened around 168,000 years before that, but it took the light from the event that long to reach us. A better title might be "A supernova was observed in 1987".
