This beautiful rendition of the Blue Horse Head was taken by group member Tdad. This is a very active region near Rho Ophiuchi in Scorpius. We'd love to have you in our FriendlyCosmos Discord! Check the link in Bio!

This stunning image of the Milky Way was taken by group member Laaadislav! Rarely is a milky way image captured and presented with such depth. Amazing capture and amazing processing. For more great shots like this. Check out the link in our Bio!

In light of today’s shooting death of Charlie Kirk, it’s worth remembering that while Paul Pelosi was lying in the ICU with a fractured skull, vile ghouls like Don Jr. thought it was comedy content. These people don’t just enable violence - they celebrate it.

9 mil views and $200 of engagement with no credit to use my video. Content aggregator pages are 👎 The Figen FYI… reverse image or simple keyword search would lead you right to my account. Tag in comments is easy and takes no effort.

Nah. Firstly, not qualified in any way (but thanks for thinking about me) mainly but there is one important reason I could never lead (or help lead) Twitch... What I would do is not popular. What I would do, people wouldn't like. What I would do would lose money. What I would do

昨夜は、上弦の月の夜側に月面衝突閃光が出現しました!2025年10月30日20時33分13.4秒の閃光です(270fps,0.03倍速再生)。月は大気がないため流星は見られず、クレーターができる瞬間に光ります。衝突領域から考えると、現在ピークを迎えている、おうし座南流星群や北流星群由来の可能性があります。

.Starlink my service has been down all morning. I have submitted a ticket via your AI chatbot that states there's an issue on your end. My home is down, none of my cams are operating. I need to know when you're going to respond to my issue as this is a critical and urgent outage

Here’s the reality about comet 3I/ATLAS. Yes, our The SETI Institute network now has multiple observations — and they show the comet is exactly where predictions said it would be. No drama, no mystery, no “unexpected disruption.” The recent claim that 3I “disintegrated” came from

The Boogeyman Nebula 🌌 Here's a fun astrophotography target to try with your telescope this season - but be warned, this one takes TIME! LDN 1622 is a dark nebula in the constellation Orion that resembles 'a dark figure with a head and arms' (I kinda see it) To capture this

A new region to me I've been been exploring.a small feature I noticed that lays between the California Nebula and the Pleadies. There is a small open star cluster/reflection nebula IC 348 and a small Ha field. I think this dark nebulae has the Barnard 3 designation and the Ha

If you can support my wife and I during a difficult phase my wife has been diagnosed with cancer a 2nd time. We're going to both be out of work for a while whilst she undergoes treatment again. gofundme.com/f/support-sid-…

When you look at astronomical images, it’s natural to wonder whether the colors are “real” or artificially added. The key thing to remember is that your eyes only perceive a tiny slice of all the light that exists. Most of the Universe shines outside that narrow window, in

Why are we not preparing for a large geomagnetic storm even though we have seen one of the most active weeks of flaring activity of the solar cycle? I have seen this question either asked or many posts alluding to this subject this morning. AR 4366 is certainly creating a buzz!

There is a disturbing trend right now that needs to be addressed and actively nipped in the bud... fearmongering about space weather, specifically this ongoing, large, and active sunspot cluster AR 4366. I am making this post because I have been sent countless messages from
