Gravitational waves expel black hole from galaxy centre
... to accomplish such a feat are gravitational waves. "We estimate that it took the equivalent energy of 100 million supernovae exploding simultaneously to jettison the black hole," describes Stefano Bianchi, co-author of the study, from the Roma ...

Light from the Universe’s first stars detected
... would struggle to see any light that was emitted from these behemoths before they likely exploded as supernovas. So astronomers looked to other means in which to identify the light. Previous research had indicated that the first...

Neutrino discovery helps resolve a century-old riddle
... of the fuss over a minuscule, barely-there particle that doesn’t want to be found? Although neutrinos are created in supernova explosions and in the cores of stars like our Sun, the greatest source of neutrinos happened some 15 billion...

Science begins with South Africa's super radio telescope
... details with a wealth of never before seen features, including a clearer view of previously known star-forming regions, supernova remnants and radio filaments. The centre of the Milky Way is approximately 25,000 light-years away and...

Unstoppable monster galaxy puzzles and enlightens astronomers
..., the gas cloud collapses and stars start popping out at a rapid pace. However, as the stars and supernova explosions start blasting out gases at the ends of their lives, it adds to the outward pressure. The cloud...
