A star blew up, and scientists snapped a photo of the violent explosion
Boom.Last month astronomers spotted a star that exploded in the colossal Pinwheel galaxy some 21 million light-years away — which in cosmic terms is relatively close. The outburst of a massive star collapsing on itself, called a supernova, crea.....»»
Researchers map the blind spots for achieving a low-carbon transition in the Global South
A network of over 60 international researchers has collaborated intensely over 18 months to identify knowledge gaps and opportunities needed to achieve a low-carbon transition in the Global South. They have developed an actionable research agenda to.....»»
Brightest cosmic explosion of all time: How we may have solved the mystery of its puzzling persistence
First detected accidentally by US military satellites in the late 1960s, cosmic explosions known as gamma ray bursts (GRBs) have come to be understood as the brightest explosions in the universe......»»
