My posts have apparently been pretty bangerous the last few days. Not just a banger to myself but a banger to others.

This website plays all of the departure tunes for each station on the Yamanote ring train line around central Tokyo. Real city heads will want to click Ebisu. Akihabara is the banger you hope it will be.

If you want to feel old, we are now further from the formation of the Kenorland Supercontinent than the formation of the Kenorland Supercontinent is from the formation of the Solar System.

I have maintained for a while that a History of Usenet would potentially make an amazing book (maybe it already has), since so much of present-day internet (not just social media) culture has its roots there.
What functionally broke Usenet is that at least some of the bad actors who were spamming were engaging in cancel wars with the cancelbots (message cancellation messages were in and of themselves a special kind of Usenet post w/ instructions to remove a post from a message queue).

I lived in Tucson for nine years, Raising Arizona is ineligible since it’s basically a documentary of what it was like to live there then.

Their definition of a comedy is way, way too broad, and there are movies on here that cannot possibly be meaningfully compared (screwball comedy vs rom-com vs live standup set, for instance). I also disagree with their #1, and question the entire premise.
The movie listed at #1 is so incredibly misplaced that it calls into question the veracity of the entire list. It belongs on the list, yes, but SO MUCH further down. An absolute, credibility-wrecking flub. Boo, @variety.com! Boo!

Fun fact: instruments are used to describe the rhythms of the system, pre-impact. Drum bass represents Didymos' rotation while the snare follows Dimorphos' orbit. The rhythmic parts are complemented by shrieking vocals and ethereal synthesizers fitting the outer space theme of the song.

When I am not studying asteroids, I write songs about them ;)
Exactly 4 years ago, I released a track to celebrate the success of the DART mission. The song is obviously called "Dimorphos" !

I believe it’s one of those things where they wanted to beat up on England but didn’t want to formally recognize or ally with the nascent USA because “American colonies deserve independence” wasn’t a message they wanted to catch on.

Happy 57th to the mighty “The Beatles” LP, released today in 1968! The Get Back sessions story is very much an extension of the White Album experience — they reconvened at Twickenham less than 6 weeks later! — so I’ve written plenty on it. Tagged here! theymaybeparted.com/tag/white-al...

Yes, eventually long-period comets are going to be the most important missing piece, and it might be that finding them when we can and planning for a late-stage mitigation is the best we can hope for.
If I understand your question, we should be able to find low-albedo objects with NEO Surveyor.
