Hello BlueSky! I’m a spacecraft systems engineer, currently working on crewed moon landers. I’ll mostly be lurking around here, appreciating your space, science, and engineering related content, and maybe occasionally sharing a mediocre astrophoto of my own now and then. See ya around! 🦋

One thing photos don't capture is the awesome immensity of these structures filling the sky, bridging the boundary between Earth and space.

Ha! It looks like Avi Loeb silently edited his Medium post about the Perseverance Navcam images, after being called out for his wrong interpretation.
While he previously claimed the image was of 3I/Atlas, he now says the claim came from "social media". 🔭

For the first time ever, astronomers have unveiled the shape of a supernova explosion just a day after detection, as the blast was breaking through the star’s surface.
Achieved by our VLT, this feat will help us understand how massive stars die: https://www.eso.org/public/news/eso2520/

Stony Ridge Observatory, Los Angeles County, 34N latitude. #Aurora kicked into overdrive around 8:30 pm PST (4:30 UTC). It was easily naked eye visible for about 1 hr as pink glow.

These must’ve been fun drives! Relatively high tilt on loose regolith with differentially articulated suspension.. rover planners would’ve been a little nervous here, but definitely earned their pay.
Ah, Curiosity climbed out of the trough. This 360° panorama was acquired two days ago.

One of my all-time fave images. See the bright star just to the upper right of the cluster? That's Sher 25 and it will explode in <40,000 years. You can see a ring and wisps of gas on either side of it; it's the same kind of star with the same structure that blew up to become Supernova 1987A.

Since @rkinnett.bsky.social just posted the Heart of the Heart Nebula, bringing back my version. Ryan, my 10" RC doesn't have quite the resolution of that 30", but I shot dual narrowband and got more dust and O[III] LOL. 🔭
![Melotte 15, the Heart of the Heart Nebula, shot in dual narrowband, with a color palate that makes H-alpha gas look yellow and O[III] (ionized oxygen) appear blue. There are twisting pillars of gas and dust lit up by nearby stars.

Learned that an anonymous outside expert on submersibles did an interview with the OceanGate Titan investigation, and they released a transcript, with all the names redacted. The first line of his first answer? "I'm sure you're familiar with my film Titanic."
