Do Telescopes Actually Take Colorful Photographs Or Are The Pretty Colorful Photographs Of Galaxies That

Do telescopes actually take colorful photographs or are the pretty colorful photographs of galaxies that we know colored afterwards? If a human was floating through space, would space look colorful to them?

So some pictures are taken in different wavelengths to see different characteristics. (infrared wavelengths to see through thick gas and dust, xray wavelengths to see highly energized regions)

But, in the visible wavelengths you are seeing the colors. They’re just enhanced brighter than they might be.

For example, I took this picture of “the California Nebula” using a camera (Canon 60Da) attached to a telescope. This shows one exposure, and the background is red due to effects of the camera (which you subtract):

You take multiple exposures, combine them, subtract the background effects & adjust the color a little and get this…

08.12.2017; My Arabic Exam Is Really Close, So I Must Start Working Harder Now. I Don’t Think I’ll

08.12.2017; my arabic exam is really close, so i must start working harder now. i don’t think i’ll do great because i’m way behind my classmates (i joined the class two months later than them), but i feel like i’m learning so much, i feel way more confident with the language now, and it makes me so happy ♡

also, i started a new book under my father’s recommendation: ‘the seven minutes’ by irving wallace.

Almost Everyone Loves Space. We Are All Fascinated By Some Aspect Of The Universe At Some Point In Our

almost everyone loves space. we are all fascinated by some aspect of the universe at some point in our lives, whether that aspect is the changing colours of the sky or the millions of stars and clusters of stars in our never-ending galaxy. as someone who plans to study astronomy and cosmology when they grow up, space definitely means a lot to me. the sad part is that we know so little about the universe, even after studying it for centuries. but what we do know now is what’ll help us make huge new discoveries, so here’s a masterpost of common questions/answers + resources for learning more about something we know almost nothing about - the universe!

How Our Solar System Will End In The Far Future

“Gravitational ejection is about 100 times more likely than a random merger, meaning our star and the remaining bound planets will probably be ejected into the abyss of now-empty space after around 10^19 years. But even at that, with Earth orbiting our stellar remnant and with nothing else around, things won’t last forever. Every orbit — even gravitational orbits in General Relativity — will very, very slowly decay over time. It might take an exceptionally long time, some 10^150 years, but eventually, the Earth (and all the planets, after enough time) will have their orbits decay, and will spiral into the central mass of our Solar System.”

Worried about the environment of Earth today? Here’s a sobering fact: we already know how it’s all going to end. Not just when the next ice age will come or the next supervolcano will blow, but on cosmic scales stretching billions of years into the future and beyond. From the death of life on Earth to the end of the Sun, we can predict some major catastrophes our Solar System will face. But even after the Sun has died, the Earth and what’s left of our parent star will likely stick around for more. The matter expelled by our Sun will ignite new stars, which will die as well. White dwarfs will cool off into black dwarfs, and the Universe will go dark. And yet, thanks to gravitational effects, more interactions, on long enough timescales, will still remain.

Come get the long-term story of the future of our Solar System and see how it all will, in the ultra-distant future, come to an end.
