Researchers from Tel Aviv University and the University of Tokyo have identified a rare “electron-capture” supernova, and in the process, may have shed light on an astrophysical mystery dating back nearly 1,000 years.
An electron-capture supernova occurs when a star eight to nine times the mass of the Earth’s sun explodes. A thermonuclear supernova occurs after the explosion of a white dwarf star that has gained matter in a binary star system. A core-collapse supernova occurs when a massive star runs out of nuclear fuel and its core collapses, creating a black hole or a neutron star.

Paso Ancho, Tierras Altas, Chiriqui Province, Pana (213.2 km N of epicenter) [Map] / Light shaking (MMI IV) / rattling, vibrating / 15-20 s :
I felt the whole house shake, but nothing fell over or broke. Our dogs seemed to be aware of it. It woke my husband from his nap. It lasted for about 15 seconds. It was felt by friends in Cerro Punta and Boquete. | 6 users found this interesting.
Is anyone concerned about a tsunami since it was off shore and fairly strong at 6.2?
