'We understand that there's a relationship between how galaxies grow and how black holes at the centre grow, but we don't really know exactly which one is driving which.'

"It's the biggest bang since the Big Bang observed by humanity," said Caltech physicist Alan Weinstein, who was part of the discovery team.

Astronomers say the mystery object is the only one they've ever seen that's heavier than a neutron star, yet lighter than a black hole.

A supermassive black hole caused an explosion large enough to swallow several galaxies, astronomers say.

A woman who discovered eight comets yet made roughly a quarter of her brother's salary was one of several scientists honoured on Tuesday night at the University of Saskatchewan.

The widespread kudos given to Katie Bouman on Twitter was deemed objectionable and excessive by people in some corners of the internet.

 A language professor has given a Hawaiian name — Powehi — to the black hole depicted in an image produced in a landmark experiment.

Katie Bouman, 29, wrote one of the imaging algorithms that helped piece together the photo by filling in the gaps in imaging data obtained from the telescopes.

The picture may seem underwhelming to some. Artist’s renderings or simulations of black holes in the past have looked very similar — here's why it matters.

The team includes Avery Broderick, an astrophysicist and associate professor at the University of Waterloo.
