This and the later XDF (eXtreme Deep Field) surveys still raise the hairs on the back of my neck every time I look at them. It really puts our human scale and importance in perspective.
- coldcode 6y agoIt's hard to imagine that the tiniest pixel spec of a galaxy hold hundreds of millions or more of stars like our own which might have planets with people on them. Of course they might also be 12B years gone.
- dghughes 6y ago> It really puts our human scale and importance in perspective. Speaking of scale a new large structure was discovered a supercluster which has been named "South Pole Wall" it;s 1.5 billion light years in length. https://www.youtube.com/watch?v=lnUUKJMAmFo https://www.youtube.com/watch?v=lnUUKJMAmFo

- dghughes 6y agoAnton the channel owner puts links to papers relating to what he is discussing. The paper he linked to is not very long: https://iopscience.iop.org/article/10.3847/1538-4357/ab9952 https://iopscience.iop.org/article/10.3847/1538-4357/ab9952
- caiobegotti 6y agoThis almost makes me dizzy: https://en.wikipedia.org/wiki/Hubble_Ultra-Deep_Field#/media/File:XDF-scale.jpg https://en.wikipedia.org/wiki/Hubble_Ultra-Deep_Field#/media... (it's a picture of the night sky showing what exactly Hubble was imaging with the Moon for scale) I never really understood how XDF is only that tiny patch of the sky and yet it has a godzillion of galaxies inside it!
- ctdonath 6y agoTIL: Moon covers 0.5°.
- brianpan 6y agoThe Sun- also 0.5°
- alejohausner 6y agoWow, they're both the same size! What a cool coincidence! Just think what would happen if the moon passed exactly in front of the sun! Has it ever happened? Has anybody looked up at the sky when this happened? I wonder what it looks like.
- nojvek 6y agoYeah full solar eclipses are a lot of fun. I had an experience in Seattle a couple of years ago. They perfectly align and all you see is a thin ring from the sun flares. In that perfect eclipse, you can look at the sun with the naked eye and it’s beautiful and humbling. Like the day suddenly turns into a night for a few minutes. The TV series “Heroes” was all about this eclipse. It’s a fun show if you enjoy this kind of things.
- titzer 6y agoI witnessed the 2017 total solar eclipse in person. Very eery feeling. It's worth noting that you should still not look at the sun during a total eclipse as the corona is still bright enough to do damage, and your pupils are dilated.
- mixmastamyk 6y ago> look at the sun with the naked eye Not recommended.

- MengerSponge 6y agoIf you haven't yet, you should read Vonnegut's short story "The Euphio Question", which was written well in advance of deep field, but is eerily complementary.
- Ma8ee 6y agoJust imagining the interstellar space does it for me. Our planet is a marble in a cathedral compared to the solar system, and between stars not even a speck of sand.
