The Largest Structure in The Universe 🏆 It’s named BOSS. What do you think it looks like?? 🤔 The Boss Great Wall is a supercluster of galaxies that span over a billion light years across. This makes it the largest structure we’ve ever observed. It’s named after the Baryon Oscillation Spectroscopic Survey - an international effort to map galaxies and quasars. The wall is made up of 830 separate galaxies that gravity turned into four superclusters; connected by massive filaments of hot gas…

Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.

Betelgeuse was captured by astronomers who used infa-red imaging on the Very Large Telescope (VLT) at the Paranal Observatory in Chile.

If the universe is expaning evenly, how is it possible for galaxies to ever collide? Shouldn't they become more and more distant from each other as the universe expands?

Buzz Lightyear's Box (Spaceship): I always liked the Toy Story movies. At first, I could not find anything to do on these movies. But, looking a little more, I found the Buzz Lightyear's box that seemed pretty easy to do. It was just about finding the design! Material : Glossy p…

Hot stars burn brightly in this new image from NASA's Galaxy Evolution Explorer, showing the ultraviolet side of a familiar face. At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way's largest galactic neighbor. The entire galaxy spans 260,000 light-years across.

New Dimension: Nebulas Are Even More Amazing in 3-D - IC 1396 With a bright, bluish star at its center, the gassy star-forming region IC 1396 spans hundreds of light-years in the constellation Cepheus. Finnish astrophotographer J-P Metsavainio has rendered some spacescapes in three dimensions, using his own photographs as a starting point. "NOTE: This is a personal vision about shapes and volumes, based on some scientific data and an artistic impression."

"Galaxies, galaxies everywhere - as far as NASA's Hubble Space Telescope can see. This view of nearly 10,000 galaxies is the deepest visible-light image of the cosmos. Called the Hubble Ultra Deep Field, this galaxy-studded view represents a "deep" core sample of the universe, cutting across billions of light-years."

This one is a composite of 2.5 hours of H-alpha from my QHY9 CCD and 2 hours of RGB from my modified Canon XSi DSLR. Both through my William Optics 66mm triplet at f5.6. They didn't line up perfectly, but if you don't look to closely it's a reasonably nice blend of nebulosity from the h-alpha data and star colours from the RGB data. Framed it just for kicks.

BUZZZZZ!

On a large scale the cosmos should be plain, but it’s not. Windows into other dimensions could explain mysterious objects billions of light years across
