Not now, super-massive runaway black hole!
Astronomers made a truly mind-boggling discovery using the JWST:

A runaway super-massive black hole, rocketing through space at a staggering 1,000 km/s, leaving a 200,000 light-year-long tail in its wake in which gas is accumulating and triggering star formation.

James Webb Space Telescope confirms 1st 'runaway' supermassive black hole rocketing through home galaxy at 2.2 million mph: 'It boggles the mind!'
"The forces that are needed to dislodge such a massive black hole from its home are enormous."

Stephen Miller is a horrible racist in the sense that he is actually not that good at being racist.

What looks like an early example of a Millennium Falcon styled hat, is worn in this etching from 1524 by Frederick the Wise, Prince-elector of Saxony from 1486 to 1525. The powerful defender of Martin Luther would have surely joined the rebellion along with Chewbacca. #skystorians

Despite frequent remonstrations from digital archivists, Persephone never accepted that she could not photocopy a whole book in one go.

Alex Abramovich did a beautiful job on this profile of Willie Nelson--and then had the good wisdom and humility to defer to Dylan to capture it far better than any longform writer could (or, more to the point, convey why it can't be captured), in a single paragraph.

Glimmers of light in dark times.
