Postavili jsme si vlastní dalekohled 🔭

Pár čínských zrcadel za $30, tři hliníkové trubky, nějaké šroubky a pružinky, PLA struna do 3D tiskárny. A to je celé.

It's also the sort of business that I feel like any state foreign intelligence service ought to be willing to fund. Just in case something they regarded as not being useful to them in space needed to be de-orbited in a responsible and timely manner. I feel like we should try to persuade the band to capitalise on that... 🤪

Regardless, astronomers of the world will be willing to give Space Junk Removal Service a listen ❤️

"Each section of the sky will be recorded around 800 times using the telescope's 3,200-megapixel camera...Every 24 hours, #Rubin will generate about 20 terabytes of data."

This Aussie Town Might Be a Portal to Space (Hear Me Out)

I was meant to be installing an observatory dome at Perth Observatory… but somewhere along the way, I stumbled into Southern Cross, Western Australia — a tiny outback town where every street is named after a star.

Like, actual stars. You’ve got Sirius Street, Betelgeuse Boulevard, Vega Terrace… I thought I was in a galaxy brain fever dream. 😅

Come with me as I explore this unexpectedly cosmic place, get weirdly emotional about signage, and wonder how no one told me this place existed sooner.

If you’re into astronomy, quirky travel discoveries, or just want to hear me lose my mind over road names, this one’s for you.

#Comet Holmes from the #Hubble Space #Telescope

Comet 17P/Holmes' dramatic brightening remains a mystery. Its dust coma, illuminated by the Sun, is visible in the night sky. Hubble's images reveal a dense dust cloud near its nucleus but no clear fragmentation. Astronomers worldwide continue to investigate this curious phenomenon.

TIL #Télescope #LSST
(Large Synoptic Survey Telescope)

Le miroir primaire et le miroir tertiaire sont sur le même support !
Du coup ça fait un gros trou dans le primaire quand même !

Du coup ça n'a plus vraiment de sens de parler de diamètre brut (8,4 m) pour mesurer la sensibilité du télescope, si ?

On devrait plutôt parler de surface de collecte en m² ou alors de diamètre-équivalent-primaire (6.7 m).

Rubin's #Galaxy

#Hubble captures UGC 2885, a giant spiral galaxy 232 million light-years away and 800,000 light-years wide with 1 trillion stars. It's part of a study on galaxy growth and honors Vera Rubin's dark matter research. A new coin and observatory commemorate her contributions.
