Something a little upbeat for the soundtrack today. I'm in an unusually good mood. I've been writing fiction and it makes me happy.
I think the arc of launch is peculiarly beautiful.

Probably a little overexposed, but it shore is purty.

I think Carl Sagan was the first one to say this. In any case, remember that much of you was once a star.
We’re made of star stuff!

"Where are the middle-sized black holes" has been a puzzle for some time. Maybe here?
Astronomers detect a new class of black holes

1. Astronomers have identified a mid‑sized (intermediate‑mass) black hole at the heart of Omega Centauri, a star cluster believed to be the remnant core of a small galaxy devoured by the Milky Way .
2. This black hole is estimated… pic.twitter.com/VP6IKgLRrX

Definitely keep looking up. The last bits of this hit a house near one of the PJ editors' house.

I'm not going to say it again, you get the idea.

A lot of people don't remember this anymore, but this was after an emergency re-entry in the Pacific.

It's #NationalSunglassesDay, so you know the drill. Time to share this truly iconic photo of Neil Armstrong and Dave Scott after splashdown of the Gemini VIII mission pic.twitter.com/98sfNEcd7F
Gemini VIII Emergency Re-Entry: A Close Call in Space On March 16, 1966, Gemini VIII, crewed by Neil Armstrong and David Scott, faced a harrowing emergency during its mission. The objective was to perform the first-ever docking with an Agena target vehicle, a critical step for Apollo’s lunar ambitions. The docking succeeded, but shortly after, a stuck thruster in the spacecraft’s Orbital Attitude and Maneuvering System (OAMS) sent Gemini VIII into a violent, uncontrollable spin—reaching nearly one revolution per second. Armstrong, with remarkable calm, deactivated the OAMS and used the Reentry Control System (RCS) to stabilize the spacecraft, expending 75% of the re-entry fuel in the process. With no fuel for further maneuvers, Mission Control ordered an immediate re-entry. Gemini VIII splashed down safely in the Pacific Ocean, about 500 miles east of Okinawa, and the crew was recovered by the USS Leonard F. Mason. This heart-pounding incident showcased Armstrong’s piloting skill and NASA’s ability to manage crises, paving the way for future missions.
Galaxies are always cool.
Using Hubble, researchers will study hundreds of galaxies that (like UGC 11397, pictured here) harbor a supermassive black hole that is gaining mass.

Getting astronomy out of visible light along is doing amazing things.

So that's it for this Friday. As always, I love getting comments. Don't forget daily space, sky candy, and space science at my Substack The Stars Our Destination. And come back next week!
