Quasars’ distance no longer in question
Astronomers now know quasars live around black holes in remote galaxies, but 50 years ago, one researcher argued they were much closer.

Black hole smashup generated yottawatts of power
For a split second, LIGO’s black hole collision generated 36 septillion yottawatts of power, or 50 times the power from all the stars in the universe.

A fast radio burst’s home galaxy may not be known after all
The recently claimed host galaxy of a fast radio burst may have been signs of a snacking black hole instead, study claims.

Repeating fast radio bursts recorded for the first time
Until now, ephemeral blasts of radio waves from other galaxies have never repeated; this one erupted 10 times last year.

Black hole heavyweights triggered gravity wave event
Those gravity waves came from two black holes more massive than any known outside a galactic core and formed in an environment different than the Milky Way.

Planets may emerge from stellar duo gathering icy dust
Gas freezing onto dust grains around a binary star could be setting up a site where comets or even planets might someday form.

‘Gravity waves’ is an OK way to refer to gravitational radiation
There’s not lexicographical basis for complaints that ‘gravity wave’ is incorrect usage for gravitational waves.
