Hello there, I'm having trouble locating accurate magnitude values for comet C/2023 A3. Many websites seem to have outdated information. Do you know of a reliable source where I can find them? Thanks!

As seen from Point Fermin Park in San Pedro CA.

Obviously, we now know there are many earth like planets out there, so if any of these planets have life, do you think there will be intelligent humans like us or human like creatures? Or what are the chances some alien race actually have big green heads and big purple eyes?

Years ago there was a TV series on either science channel or similar about the universes time line and it used celestial objects/nebulas/galaxies to explain beginning middle end of the life of stars I think so nebula were involved. I thought it was a great explainer but I can't figure out what it it. I've tried a few of The Universe episodes, but no luck. I only recall one of the nebulas mentioned. Carina. Any suggestions would be great.

I'm located near Tampa Florida, and due to power outages and cooler weather, I've spent more time outside. Last night roughly 8:30pm, while stargazing, a bright light appeared. It looked like a bright star or planet. It was stationary. It shined for a second or two and then disappeared. Several minutes later, it happen again but this time it was a but more west that the first one which was more north.

I tried looking this up but couldn't find anything. And I may not even be using the correct search terms since I'm at a loss of what I saw. I've seen falling stars, but I've never seen stationary, brief lights/stars. Both were high in the sky and truly looked like a bright star or planet.

Thanks for any info you could share. I'm so curious what I saw.

Venus to the left, Arcturus on the top right corner and above C/2023 A3 (Tsuchinshan-ATLAS) you can see the Serpens Caput constellation

So a few weeks ago I saw on TikTok a website where you can fly through the whole universe and zoom in everywhere on every planet etc.. It was very well detailed. It was not Stellarium it was far from that. Much better graphics. Do you guys know what I'm talking about?

Hey everyone!

I've put together a detailed tutorial on how to stack and post-process astrophotography images using Siril software. This guide walks you through the entire process—from loading your captures to enhancing your final images. If you're into astrophotography and want to make the most out of your data, this guide could be helpful.

Feel free to leave feedback or ask any questions.

I was looking east from a spot in the north Georgia mountains, in a field in Rabun county. This was at 9:21 pm EDT on an iPhone 13. These are the foothills of Appalachia so there are mountain ridges but they are ancient and not very tall, relatively speaking.

I am curious about the small “V” right above the fence in the lower left portion of the image. I was balancing the phone on something sturdy and the other stars don’t have any movement so I don’t think it is because of shaking but I could be wrong. The V would not have been very high in the sky, I don’t know the exact degree though.

Camera artifact, satellite, or something else? I didn’t really notice it until tonight when I decided to check my aurora pics for any signs of the comet but I’m quite sure this is facing east so I don’t think it’s the comet.

Forgive the quality but I hadn’t seen too much in the way of this guy submitted.

There was a post yesterday of the aurora from the Colorado Rockies which looked amazing, and I've read about dark sky parks in Pennsylvania and Texas that would be great. My guess is that a desert area (Arizona/Nevada) would be good but I'm also worried about scorpions and snakes.

Ideally I'd go to a park that is most likely to have good weather (I'm in Canada and it's almost always cloudy or too cold to be outside on a December night) and where I don't have to worry about bears, bugs, or other worrying creatures, and would appreciate some help.

Hoping this question doesn't violate the rules. Thanks!

I would love to know if there has ever been recorded seismic activity on the moon so strong, that you could potentially witness the shaking with the naked eye.

When I was a child, my family and I were in Long Island, NY visiting my half sister. On that night when we were leaving, the adults took their moment to finish up their conversation and say their goodbyes. Completely disinterested, I took the opportunity to do some sky gazing, as my hometown of the Bronx never had a safe place with a decent view of the sky (which is littered with light pollution anyway).

To this day I have a crystal clear memory of watching the moon shake in its place. This was not a dream, I vividly remember this day. If it’s not possible, what other explanation could there be other than I may have had some sort of hallucination?

Thanks in advance, I am super curious.
