Veil #Nebula: Wisps of an Ancient Supernova
The Veil Nebula, a supernova remnant in Cygnus, is the remains of a star that exploded 7,000 years ago. Now faint and sprawling across an area over five times the full #Moon's size, it's 1,400 light-years away and visible only through telescopes. This image captures its glow in hydrogen red and oxygen blue.

La nuit dernière aux rencontres astronomiques du printemps : le fantôme des binos. Un exceptionnel instrument composé de deux miroirs de télescope de 600 mm de diamètre montés en binoculaire. La vision stéréo de la nébuleuse du cygne offre un relief à tomber par terre... #Astrodon #StarParty #astronomie #RAP2025 #telescope

Why Did I Build a Dome 3,000km From Home?? (I’m Still Not Sure)
So... I kinda said yes to building an entire observatory dome... on the other side of Australia.
Everyone said we were insane. No crew. No backup. Just a dome, a dream, and way too many snacks.
This video is pure chaos: assembling a giant research-grade observatory from scratch, battling time, tools, and the Australian sun. We got sunburnt, we got stuck, and yes — we had at least one breakdown (maybe two).
But in the end? The dome stands. And we’re kinda proud of it.
Was it smart? Debatable.
Did we finish it? You’ll see.
Was it worth it? 1000%.

Astronomy Fun in June, from Time and Date.com
"What’s Up in the Sky in June? June is all about the Sun as we shift seasons on the June solstice. Also: a bright morning Venus, two Moon-Mars conjunctions, and look out for the Summer Triangle."

Herbig-Haro 24
#Hubble captures cosmic jets from a newborn star in Herbig-Haro 24, located 1,300 light-years away in Orion B. Spanning half a light-year, these jets are propelled by material falling into the star's accretion disk and shooting out along its axis.

Spiral #Galaxy NGC 2566 from #Webb
#Infrared image of spiral galaxy NGC 2566 shows diffraction spikes from Webb #telescope, not real features. Its bright center likely hosts a quiet supermassive black hole. At 76 million light-years away, its star-forming clouds are visible, akin to the Milky Way in size and structure.

Une petite maison ! Il manque une petite serre et elle serait parfaite pour moi. Encore que la cheminée à côté de la tour d'astronomie c'est ptet pas idéal XD
Il s'agit d'une maison importante pour certains personnages.
J'ai galéré + que de raison à la dessiner.

Milky Way over Maunakea
From a dark location, the Milky Way's band of light is visible, containing billions of stars. The featured image shows this band with Rho Ophiuchi and Zeta Ophiuchi nebulae, taken from Maunakea, Hawaii beside a 2.2-meter #telescope. No #volcano needed to witness it!

Abell 31 is a large and dim planetary nebula in the southern sky trailing Orion. I piled up nearly 70 hours of integration time on this target with 10 minute narrowband subs and it's looking pretty good.
