Rare discovery! Three monster black holes are about to collide

They’re at the core of a triple galaxy merger one billion light years from Earth

NASA’s space observatory captures unusual event gone in a flash

Astronomers predict that a black hole or neutron star could be the cause for this dramatic event

The X-ray emission detected from Eta Carinae shows highly energetic cosmic rays ejecting from the massive stars

To commemorate NuSTAR’s first five years in space, the principal investigator, Fiona Harrison, has chosen her five favourite images of the mission

These winds spewing from these exotic objects can heat up and cool down in the span of just a few hours

Large numbers of the exotic object have been uncovered belting out intensive radiation

The strange behaviour of black holes has become somewhat less mysterious recently, according to NASA’s Swift spacecraft and NuSTAR satellite

A number of supermassive black holes, clouded from direct view by gas and dust, have been found

That’s one question that astronomers are asking after our current understanding of these bright explosions is challenged by new observations.

Two X-ray space observatories have teamed up to make the first measurement of a supermassive black hole’s spin.
