A red-superGiant supernova cooling at a redshift 3
Astronomers have discovered a “dynamically driven” Type Ia supernova explosion in our Milky Way. The Supernovae was observed to be nearly three times as bright as previous Type Ia supernovas. This supernova explosion is associated with “dynamically-driven” Double Degenerate Double Detonations, coined by Ken Shen, an astrophysicist at University of California, Berkeley, in his book…

A kilo nova after a long-duration gamma-ray burst
Scientists have discovered a kilonova-like star about 1,000 times more massive than the Sun. This star was discovered by observing gravitational waves caused by the merger of two neutron stars, LIGO GW170817 and Virgo GW170817. Researchers said it is one of the last remnants of a dying neutron star, which was destroyed by a “supernova”…

Firework supernova remnant is unlike any seen before
Astronomers have imaged a supernova remnant, the remnants of two comets, that they claim smashed into each other around 850 years ago. “I have worked on supernova remnants for 30 years, and I’ve never seen anything like this,” astronomer Robert Fesen said. Fesen said he has worked on supernova remnants for 30 years, and has…
