A mind-blower for a Friday evening:

This deceptively simple-looking graph is a spectrum of gravitational waves ringing through the Milky Way.

The waves may be caused by a chorus of supermassive black holes colliding all across the universe. Whoa!

Can't escape the sound of them. It's like The Tell-Tale Heart.

Uh oh. The ambitious European-Japanese BepiColombo mission to Mercury has experienced a worrisome "glitch" in its thrusters.

Engineers are scrambling for a fix so the spacecraft can enter orbit around Mercury late next year, as planned.

BepiColombo got some enticing previews of Mercury during its 2021 flyby of the planet.

These images come from the spacecraft's little monitoring camera. The real ones (assuming the spacecraft pulls through) will be far more spectacular.

After years of searching, astronomers have finally detected an atmosphere on a rocky planet around another star.

But what a strange planet it is! 55 Cancri e seems to be blanketed in carbon dioxide gas bubbling out of a global ocean of lava. Like an image out of Dante's Inferno.

One of the great frustrations in the search for life in the universe: It's much easier to study extreme, hellish planets (huge, hot, etc) than to study the moderate worlds where life could plausibly exist.
