I've been looking for more space content on YouTube to fall asleep to. I've played through SEA, Cool Worlds, HOTU, Astrum, Kosmo... but looking for some new ones/hidden gems. TIA 🌌🪐
I’m fortunate enough to be meeting a few of the Apollo astronauts at a private event soon. Do any of you have a favorite Apollo poster? I’ve just been looking at the ones on Amazon for them to sign, but I feel like there could be better quality ones somewhere.
I have a friend who loves star gazing and astronomy, but they have cataracts and the surgery didn't go well. Does anyone have any ideas for how they can continue to enjoy the night sky?
I've got a total noob question but I'm just not satisfied with explanation: Jupiter is made mostly out of gasses that's why it's called the gas giant. I am not arguing about that but how can that be? Surely there must be some core/planet inside that allowed the gasses to gather around. Would gasses be able to just form a planet on their own. And if there's some rocky core or something how can it trap so much gas to become this huge? Sorry I know it might be a dumb question but I prefer the many answers of redditors.
Edit: Thank you so much for the answers! I learned a lot!
Life is already abundant in our universe.
Here on earth five million trillion trillion (10^(30)) bacterial life forms exist on earth alone - and our galaxy is simply waiting for us to seed it with bacteria from earth that can survive anywhere including the vacuum of space such as https://en.wikipedia.org/wiki/Deinococcus_radiodurans
Consider that humans are directly evolved from bacteria. We are them and they are us, in a sense. LUCA, the Last Universal Common Ancestor, was a bacteria-like organism which ALL LIFE ON EARTH is descended from. If LUCA can survive on a hellish lavascape (early proto-Earth) then it is our duty to spread bacteria to all corners of the Universe to create life and allow it to survive and thrive.
Why not create life? Humans do it all the time. You yourself reading this are a product of it. There is no good reason not to allow life to live and thrive.
What is life? Among many viewpoints ranging from metaphysical to religious, from philosophical to scientific in nature, one basic stance is: that it is DNA that self-replicates.
Bacteria is formed from DNA - just like many viruses - and just like we are.
DNA itself forms from amino acids which are relatively common to the universe https://ras.ac.uk/news-and-press/news/evidence-amino-acid-tryptophan-found-space
These non-alive compounds have an amazing propensity for self replication. In other words, life forms relatively easily from materials that are common the universe - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7059183/
These base pairs eventually formulate into a DNA structure that exhibits Microbial Intelligence https://en.wikipedia.org/wiki/Microbial_intelligence in which these microbes begin working together, cooperating, growing, evolving, attacking and defending, forming singular tissues and beings, and essentially being alive.
What makes Earth special is that it has a magnetic field, protecting our life forms from Sol's life-obliterating radiation. But as we see with some types of bacteria (i.e. life, i.e. us -) a magnetic field is not absolutely necessary for life to live.
Why are we looking for life, when we ourselves can send life and begin evolution on other worlds. We may or may not survive in the end, but LUCA (bacteria) can - as we saw it survive on the inhospitable proto-Earth if it we give it that chance.
Humans are not special. We are among the more latter creations in evolutionary history than other creatures. Dinosaurs superseded us by many millions of years. And they'd still be ruling if Big Space Rock hadn't come.
What if we realized there was a species living in our solar system right now, capable of space flight and conducting interstellar exploration https://en.wikipedia.org/wiki/Voyager_1 - that is currently terraforming a world https://www.un.org/en/climatechange/what-is-climate-change and capable of creating (seeding) life on other worlds? https://www.nasa.gov/missions/mars-2020-perseverance/could-microbes-survive-a-trip-to-mars-we-asked-a-nasa-scientist-episode-1
We are the aliens that the universe is looking for. The universe should be looking for us.
We have more life forms on our world here than there are planets in our galaxy.
Hello, I'm currently on vacation in Poland (UTC+1) and we just saw something that we think might be the supernova that was expected this year. Can anyone help with clearing things up?
It was pulsating in fixed intervals and it moved across the sky in a matter of appropriately 10 to 1 5 minutes.
Unfortunately due to this subs rules I can't post any pictures but feel free to message me if you would like to receive them in case this would clear um what I mean.
Edit: here is a link to a video I took: https://imgur.com/gallery/Si85Ew2
And thanks for the clarification
As the title says, my kids love space! I was looking for a show that teaches them facts but unfortunately couldn't find any that were suitable for young children, i found a channel called solar balls which is good and they enjoy but the facts are a bit to in depth. So i did some research and some practice and made my own animation for kids. That is all about space and easy to understand facts for kids and adults. The channel is called planetparty on youtube, if you would like to check it out.
Edit: iv had a few messages about the channel i left it in the comments, but I'll try to add it here. Hopefully, it works planetparty. If you would like to check it out, any feedback would be amazing. Also, thanks a lot for all the advice and links. I'm gonna sit down with my daughter tonight and show her!
