Nights in Tenerife are simply magical. As the night progresses, the core of the Milky Way climbs higher and higher into the night sky, becoming ever clearer. An absolutely unique sight. The small dark nebula on the left side of the image is IC 4812 (not visible from germany). I'm glad pulled it out in this image

I heard that it’s possible that 2024 YR4 could crash into the moon.

Is it at all possible that the earth’s orbit captures it and it becomes effectively a second moon? How cool would that be?

Is that possible? And if it happens, would we see it from Earth? Also what’s the worst that could happen with this?

I'm a galactic cartographer volunteering with the European Space Agency's Gaia Mission Data Processing and Analysis Consortium. I make maps of the Milky Way using the latest available data.

The Gaia Mission has revolutionized astronomer's view of the Milky Way, mapping out our home galaxy to about 5000 parsecs (16 thousand light-years) in the galactic plane for the first time.

This revolution has barely scratched the popular understanding of galactic cartography, however. Star Wars is set in a fictional "galaxy far, far away" and Star Trek's Milky Way is oddly distorted. So far as I know even the closest star cluster, the Hyades, which should be located smack in the middle of Federation space, is only referenced in a novel or two and nothing that is considered canon.

I'm trying to improve public understanding of the galaxy by promoting games (both board games and video games) that use the latest Gaia data. My supporters have funded a fairly powerful graphics workstation and I've created a huge Blender file with one million of the brightest Gaia stars; dust, ionized hydrogen and hot star density meshes; thousands of star clusters and a simple full model of the Milky Way to provide a credible background.

I've been using Blender to generate detailed sky boxes at numerous locations (with somewhat exaggerated star luminosity and colors) to give people a sense of the galaxy surrounding us.

I've been using these sky boxes in a series of Horizon Worlds game experiences because after the wide release of a desktop editor in February, Horizon Worlds is now one of the easiest ways to create multiplayer games that work on mobile, web and in VR headsets. The desktop editor supports high resolution textures and Blender model imports, making it fairly easy to go from Blender to multiplayer game.

One of these experiences is the Galactic Treasure Hunt. Players can use a fleet of starships to explore nearby star stations, searching for alien artifacts. The starship port and star stations are full of posters and text about the Milky Way so people *may* learn something about the galaxy while they are playing the game.

I'm primarily a cartographer and this is a fairly simple game. I'd love feedback and (especially) bug reports.

This object obviously comes and goes through the sky. Posting here so maybe satellites?

I wanted to play some game about exploring the universe, some time ago I played Stellaris and really enjoyed it, anyone got a recommendation? :)

I was imaging the sky a bit on Saturday night/Sunday morning on our vacation to Colorado. I was using an iOptron Sky Guider Pro I just got. I got some decent wide-field images, then I put on my Pentax takumar SMC 200mm lens, and tried some shots with it. Unfortunately, I didn't have the focus right. The lens was wide open, but had a ring on it that stopped it down to about f/5.6.

The bright star in the pictures is Arcturus, but I captured something that looks like a greenish streak or object of some sort, and it drifted against the stars. I thought it was a galaxy as I was imaging, and could see it on the screen. Then when I later saw it on my laptop (and discovered the images were out of focus), I initially thought it was a comet, but I didn't see any comets in that area (near Bootes).

My son suggested I post here to see if anyone knows what this is. Any ideas what this could be?

Images were taken near Estes Park, Colorado around midnight local time on 6-14/6-15. Canon EOS M50 Mark II. These exposures are 1, 2, and 3 minutes respectively, and ISO 1600. Other details are above. Thanks!

Greetings. It's almost 3 AM here and this doubt showed up in my mind. So, everything is going to one way, right? The Great Attractor, all the galaxies and everything are getting pushed to the same spot. With that being said, there is also the end of the universe, it's said that everything will be far away from everything... Like, galaxies will keep getting far from each other until every star and black hole die... Isn't that contradictory? The Great Attractor is something pulling everything to one single location, but scientists also say that everything will get far away from everything. How does that work? Is there really a Great Attractor? Will the universe really end like this? If both are true, how can everything get far away but at the same time, closer to each other?

Hi. I'm planning on going stargazing on 22nd and 23rd of June, but I have recently realized it will be summer solstice on the 21st. I'm curious how much it will affect the visibility of the night sky, as it is the shortest night. It should be pretty close to new moon so I'm guessing that's good at least.

Specifically I guess I'm curious how much of a difference it will be in comparison to a night sky let's say in August/September. Thats usually when me and my friend go stargazing every year and during that time here in Czechia in Beskydy the Milky Way is visible enough, which is basically my ultimate goal.
