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.

Black holes are phenomenally dense celestial entities with gravitational fields so powerful no matter or light can escape.

The British physicist, who gained international acclaim for his work on black holes, was laid to rest during a service at London's Westminster Abbey.

New Alberta-led research has discovered black holes are girded by electromagnetic winds that not only influence how the super-dense interstellar bodies gobble up anything that gets too close but also how they affect vast areas of space around them.
