Light shed on a superluminous supernova which appears to have exploded twice. An international group of researchers has used the GTC to observe a superluminous supernova almost from the moment it occurred. It has revealed surprising behaviour, because this supernova showed an initial increase in brightness which later declined for a few days, and later increased again much more strongly. The scientists have used the data observed at the GTC and has combined them with other observations to try to explain the origin of the phenomenon. Ref. Source 8g.

Supernova (Hover)
Supernova collides with nearby star, taking astrophysicists by surprise. In the 2009 film 'Star Trek,' a supernova hurtles through space and obliterates a planet unfortunate enough to be in its path. Fiction, of course, but it turns out the notion is not so farfetched. Source 6o.
