Dying stars called collapsars may forge much of the universe’s gold
Spinning stars that collapse into black holes could help explain the origins of heavy elements such as gold and silver. Source: https://www.sciencenews.org/article/dying-stars-called-collapsars-may-forge-much-universe-gold4…
What a nearby kilonova would look like

The M87 black hole image showed the best way to measure black hole masses
The first image of M87’s black hole suggests it is 6.5 billion times the mass of the sun — close to what was expected based on how stars move around it. Source: https://www.sciencenews.org/article/m87-black-hole-image-best-mass-estimates-star-motion4…
