The furthest object known to man! 🔭👀🌌
Welcome!
Today I want to take you far far away, to the edge of the universe, we´ll take a look at the furthest object known so far. The furthest object is simultaneously the oldest object because the light we receive from it takes time to travel in distance. Actually if we look at such a distant object there are more factors playing a role, but for now we look at the simplified version of the story.
Indeed it´s one of the youngest galaxies we´re able to observe. It´s about 13,4 billion lightyears away and therefor that old.
The universe itself is around 13.8 billion years old, that makes GN-z11 a galaxy which formed shortly after the universe came into existance. That´s why we can not see a typical galactic structure within that object but rather an orderless structure.
For now let´s take a look where good old
GN-z11 came from.
In order to look at such great distances we need to have a telescope which gathers A LOT of light, either by size or by exposure time. We choose the latter, with the help of the Hubble Ultra Deep Field NASA was able to get an exposure time of 96+ hours. The outcome was an image with 10.000 galaxies on it. This was 2004. They took it a step further and created the Hubble Extreme Deep Field with an exposure time of 23 days, revealing another 5.000 galaxies of which one is GN-z11. In order to help you finding it follow the crosshair.
I further encourage you to take a look at the HEDF in high resolution, zoom in, and wander around the galaxies! Great views!

Always a fascinating topic. It exceeds my imagination most of the time when I think about that the points and light we see has actually already moved on. In this case, it took billion years to arrive on earth and so the object may look completely different nowadays.
I hope to read more of such topics from you in the future :-) it will not be bad for me to learn something new O:-)
Hey Mr Pe! Everything moves, everything rotates in the universe, we and our sun too, our milky way, it's crazy.. The universe itself maybe too?
GZ-n11 surely looks different today :-D
You'll get more from me and astronomy! See you
Oh I like your good karma trail! I will also get back to eSteem I guess. I abandoned it because of bad stability. Looks fine now though
please upvote my post and get small sbd
@aravindgre
Sure thing!
Far out man, groovy! Don't dream it, Steemit!
thank you for dropping by @bigskykilroy
I do both. Dreaming it and steeming it ^^
see you around
You're welcome.
First of all it's a mystery name - GN-z11 and additional you gave short and interesting facts for all types of readers, for pros and for normal people. Thank you @ flurgx
Have a good time
Thank you for reading and commenting!
Heute hab ichs dann auch auf Deutsch übersetzt :-)
