I've always been deeply fascinated with space myself. I love reading about it and imagining what distant planets would be like. My favorite image currently is probably the Hubble Deep Field image. I think they said it took around 10 years to create and it's the most detailed and vast reaching image we currently have.

One of my favorites as well. Also, the first real photo of a black hole and the galaxy nicknamed Methuselah are very dear to me.

I'd seen the black hole photo a little while back it's definitely pretty cool. The moon has been making the news alot again lately.
The Chinese are trying to put a base on the moon in a few years. They recently sent 12 life forms to the moon and I think Cotton did the best. A probe carrying tardigrades accidentally crashed into the moon.
Two more semi recent little fun facts about the moon. A company tried to put advertisements on it but was luckily stopped. Nasa recently released the 3D moon kit for movie and game developers. The moon kit is a set of images that encompass the entire moon and were collected during NASA survey work.

It's not very space-related, but I looked up at the starry sky several days ago and it struck me: why do the stars look white? I mean, shouldn't they be of different color, and more to the red due to universe expanding?
Turns out the light from them is so dim that only rod cells of human eye work, giving us ability to perceive the brightness but not color. I didn't actually realize that you could just see the same scene, parts colored, parts gray-scale. I tried to observe the same effect in just a partly lit room at night, but I couldn't tell whether I actually saw the color or remembering it as things were getting dim.
Oh, and the effect of the red-shift is very insignificant, especially since ultraviolet that stars emit as well can get red-shifted into visible spectrum too.

I would totally CTB by jumping into a black hole. Seriously though, space is so fascinating.

I'm thrilled to hear people still feel awed and mystified by space. I was worried the ubiquity of science fiction had made singularities seem mundane. That would be a sin.

Just recently read that scientists confirmed we're receiving a rogue radio signal from a source some 500 million lightyears away.
"The mystery signal, known as FRB 180916.J0158+65 was first discovered in 2017, but has continued repeating steadily, albeit at a rate some 600 times fainter than the first bright flare. In their study, scientists analysed 28 bursts which took place between September 2018 and October 2019, confirming the pattern, and excitedly concluding "that this is the first detected periodicity of any kind in an FRB source."
In my opinion it's probably a pulsar, magnetar, or some other unidentified space anomaly. But who knows? If the signal is intelligent then it was sent during earths pre cambrian period. So whoever would've sent it is either long dead or evolved by now.

Saw that in the past few days. Your initial guess is probably the likely culprit, but as you said, who knows? Could be an advanced civilization. Or was.Just recently read that scientists confirmed we're receiving a rogue radio signal from a source some 500 million lightyears away.

Hey, you can see my house from here. Look I'm waving!
Eeeek space bears! We colonised the moon by mistake. Can't those little guys survive anything?
Probably true. Massive distance to travel. This is fun...
Fun fact about space:
If you get exposed to the vacuum of space you don't die from the cold, but from the lack of oxygen and the low pressure which makes your lungs explode.
Another fun fact:
A black dwarf, which is the end stage of a normal star, such as our sun, is a stellar corpse made up of crystallized carbon. It's basically a huge diamond in the sky. The universe is not old enough for stellar cores to have cooled off completely and become black. And even if it were old enough, we would still not be able to see them, as they would have the same temperature as space, and would therefore not emit any light.

Oh dear, @Underscore ... you and I have severely lowered the level of this conversation with our two latest replies
Should we do something to redress the situation? Or not? Coz I have a good joke about astronomers and heavenly bodies....You started it, I merely guided it to its natural conclusion.Oh dear, @Underscore ... you and I have severely lowered the level of this conversation with our two latest replies
Lol I've literally been waiting years for the right context to tell that joke.I have a question...
What is the oldest planet in the solar system? Think about it...
They are all the same age. They were formed from junk orbiting around the proto sun.
"You started it"
Yeah, guilty as charged! I am a bad influence on you. You should put me on your ignore list. But, please, ask me first why astronomers like to do it in the dark

Why o why do astronomers like to do it in the dark?

Who of you has had the privilege to watch the night sky in a place with zero light pollution?
I saw it once and have an intense longing for it since then.

You were being very clever. It's a very good question, and quite counter intuitive, when you think about it. If I hadn't read about the formation of the solar system, I would have probably assumed that the rocky, inner planets, had formed first, and the outer, gas giants later, seeing they are so massive.
It would be interesting to know if there is a theory about the time frame within which planets formed out of the accretion disc.
I did! And I mean zero. On a mountain in Wales in the dead of night, lost and starting to get hypothermia. I laid down and looked up and forgot everything but the stars. I've never experienced anything like it, impossible to describe.
When I was a kid, visiting my relatives who lived out in the country side. First and last time I saw the Miky Way in all its glory. A mighty spectacle.
Here's a beautiful phenomenon called gravitational lensing. What we see in this photo is not a star with a ring around it, but two galaxies.
The yellow galaxy distorts space time with its gravity. It literally curves space time around it, so the light from the background galaxy, the blue one, appears not as a dot, but as a circle. The light from the blue galaxy follows the curvature of space time created by the foreground galaxy, and it thus appears distorted to us.

Nice! I got to see it in the Scottish Highlands! But unlike you I went inside because I was dead tired from our exhausting mountain hike (it was mid January). Wales is still on my list!!
Like nails on a blackboard. Spooky and hellish indeed. This is what hell would probably sound like, if it had a soundtrack.
Did you see some of the comments? Some are pretty funny, like this one:
Everyone: In space, noone can hear you scream.
Saturn: Hold my beer!

Wow that's beautiful. How did they record this???
It's radio signals which they compressed.

I'm always fascinated watching space related vids on Youtube. And I've always had this question on my mind regarding the fact that we've searched the universe from a side to side angle, but what about straight upwards and downwards? Has NASA or any other Space Program done that before?

I think they explore it at as many angles as there are, and then some.
Love the Saturn recording - great visuals too. Thanks, @avoid_slow_death x
