The Trifid is such a sweet nebula! And just on top of the Lagoon Nebula. Moving back and forth between the two is a stargazing delight…
(and just above and east, the star cloud M24 - more delight!) (and then on to M25 and then down to M22 and then ok I’ll stop here! I call this my Milk run)

Dazzling cluster! It made me think of another one of similar shape - though more dazzling still! - NGC 3603.

Re: APOD: Earthrise: A Video Reconstruction (2024 Jun 30)
Seeing Earth from space alongside Bach's music sums up quite well how far we've come since the time cyanobacteria ruled the planet!
(but - oh the heresy! - the video cuts out the last chord of that Bach piece!) (which can also be heard on Voyager's Golden Record)

The Moon clearly shows us its best side! Its "softer" side too, which the early Earth kept warm… (while the other side was left in the cold, forced to grow a thicker crust)

Re: APOD: The Nebulous Realm of WR 134 (2024 May 31)
If you compare a Wolf-Rayet with an LBV of the exact same mass (leaving aside ejectae), which one would be most luminous? Would it be the WR by virtue of the burning core being more exposed so to speak, or could it be either one depending on various other factors?
