Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work on the Sloan Digital Sky Survey, imaging millions of stars, black holes and galaxies in unprecedented detail. If we maintain our pace, she says, we can map every large galaxy in the observable universe by 2060. "We've gone from arranging clamshells to general relativity in a few thousand years," she says. "If we hang on 40 more, we can map all the galaxies."

Darkness can also become beautiful.
_In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move._

This is my dad. He is a softwate engineer and he was recently fired because the company he worked for went out of business. We currently struggle financially and would really appreciate if you helped us until he finds a new job. Thank you all for the support, it means a lot to us 😉 https://www.patreon.com/user?u=22056926
@Sean Monclus is one billion banknote acceptable? I will send it via postal mail.

@Sean Monclus Since when a software engineer struggles to find a job? lmao
*”But over time, my fear of the dark turned into curiosity”*
How did you do that?
Because as you grow up, you come to understand that there is nothing alive in he dark that isn’t already alive in the day and there isn’t anything to be afraid of. Once you overcome childhood fear about not being to see, you start to use your rational mind to see and you can see that childhood fear is nothing more than an imagination run wild. Once this happens, you begin to wonder about thing in the dark just the same way you wonder about things in the light.
Easy… turn it into a question(s)…
P.S. fear of the dark more easily translates to fear of the unknown… the more you know, the less you fear (unless it is truly something to fear)
Curiosity. Genuine curiosity will be stronger then fear.
@Red_Tuke _Guy stronger than genuine fear?
I strongly disagree
@Ryan Kim What compels us to look even when we’re afraid of what we might see?
WHEN i was kid i WAS not afraid of the dark.
This Concerned my parents
You can so imagine her giving prep talk before going into an actual war
It’s really offputting.
I can’t . She’d make me nervous. She doesn’t lack confidence but it sounds so scripted and overrehearsed. Public speaking isn’t her strong point but sometimes I wish people in the science community would speak as they normally do among eachother
You just got prepped! Get to the battlefield 😀
She looks like the Commander of a Starship- just dropping some knowledge before beaming.
lol, exactly!
“There are dark forces in this world that will rob our entire species of our rights to understand our universe. Don’t be afraid of the dark. Fight back! Join us.”
I love her passive aggressive attitude towards the establishment.
Maybe she is pointing towards uhm uhm ets the I word
wow, another right that we have. It’s our RIGHT!!! oh really?
Dan Hazy you don’t think it is a right to learn, to acquire knowledge?
@Phoenix Uprising “rights” imply entitlement. I think it might be nice to do, but, maybe at her expense meaning no federal grants. I fail to see how she has a “right” to do this. There are many things humanity might want to do, what makes this so important? How does it benefit mankind? could these funds be better used? She sounds angry and this talk was nothing more than a plea for funding by labeling her work as a “right” an entitlement. The stars will be here long after we are gone. We have time no one will use her map to go anywhere. we have not even returned to the moon for 50 years.
Learning about the universe will help us to survive
Every single piece of knowledge has immense value. But because financial resources are limited maybe we, as humans , should prioritise those resources first towards a full stop risk of a nuclear war and climate disruption ?
i can t believe i just heard the word “besties” on a TED talk.
That was the first time I’ve ever heard the term (and i’m middle aged) I almost died! hahaha
“Fight”, “monster”, “battle,” “beast” “arsenal”. Why must we always make the unknown an adversary?
@PW You noticed it too? It sounded to me like she tried to use certain words for effect but didn’t have adequate vocabulary.
I would use another kind of vocabulary in talking about science, but I just took her words as her way to build this into her mind as a challenge. And I think feeling challenged (by the universe, in her case) is the key to be passionate about something, which, I think, is sort of all that matters.
@Danny Flo I am really put off by the militaristic language. Discovering space should be a peaceful and uniting endeavour. Not a battle, not a fight, etc.
She seems angry
@PW its a fight for funding. wow, nice map, but the whole point was to get people on her side for funding. 🙁
Not the best speech ever but she did good.
Subtle dig at governments wanting to defund science and nuke eachother. Love it.
not so subtle.. disappointing science has to become political. Nice accomplishment but, I could think of way better ways science can help humanity. no $$ for you.
Upset that the Tycho Brahe portrait came without a metal nose.
I love looking at the ancient star maps, its so cool, a magical feeling to reach back through time like that.
She looks like something from Star Trek
…and yet we know so little about the oceans on our own planet or Earth itself.
So if we fail to map all the friggin galaxies by 2060 – what then?
She sounds half arrogant half motivational. So wierd.
Mostly arrogant haha. “I lead an Army” hahaha
