Reading the arguments between nonscientists on what scientists are professing about the universe is frustrating and a huge turnoff.

Unless you've published a volumetric survey of physics and the history thereof, just stop making generalizations and authoritative claims about what's happening in the scientific community.

Instead, just talk about, you know, space.

Hopefully the Chinese start funding a Mars mission, then we might get there sooner.

did you guys know that India has its own Mars orbiter?

this it their latest portrait.

also I dunno if y'all noticed but we crashed into a comet.

these shots were taken by our Rosetta space probe shortly before contact with Comet 67P.

sometimes they simply run out of fancy names because there's too many stars.

this is IRAS 14568-6304; it's like a baby star in the middle of being born.

Amazing imagery.

 

Not to derail the topic but I watched about 2 hours of Flat-Earther videos. For a while I thought it was an elaborate joke, a bit like the Church of Flying Spaghetti Monster but I think they actually believe this stuff or they want to belive it because mainstream science is just too mairstream and the don't want to just swallow everything thelse man tells you.

They're artificially colourised, some from IR and other nonvisible spectrums and some from visible spectrum images, but not actually fake.

Pictures seems fake.

as has been briefly explained, they're definitely real.

if they "seem" fake it's because our eyes and our minds have been tricked after having become so quickly accustomed to watching the special effects of Hollywood space movies...

I actually never thought there was that many satellites orbiting Earth. The figure is something like 2,271 wit Russia accounting for 1,324 of them. ^

 

Here's a photo of GPS orbits..

I've been watching a few episodes of "How the universe works" on Netflix the last few days and what's fascinated me are Pulsars. Basically small stars that are extremely magnetised rotating at incredibly high speeds. Thank god we don't have any of those in our solar system.

 

Also it made me realise how lucky we really are as in having a (near) perfect orbit around the Sun for life to flourish where it's impossible for other planets due to their strange orbit rotations.

 

After I stopped watching I thought to myself "I wonder how much of a change in our orbit would mess things up for us?"... a few metres, a few kilometres?

 

I love this sort of epic thinking.:D

We would actually be ok with quite a bit. Equilibrium temperature is fourth-root of energy flux, so it goes as inverse square root of the distance from the source. So temperature fluctuations from fairly significant eccentricity can be absorbed into seasonal changes. A circular orbit does allow for a gentler climate over a larger portion of the surface however, so it does help.

 

And yeah, pulsar in Sol system would be bad news. In fact, any star in addition to our own would make it far less likely for habitable conditions on any of the planets for an extended period of time, let alone a massive neutron star with a galactic strength microwave death beam radiating from it.

Most of the time, the answer is that you can't. Scientific satellites, probes, and rovers tend to have filters on their optics designed to capture the most relevant data. Not to make true-color images. So the results published to public have to be false-colored.

Take a look at this damn picture. This always gets to me for some reason. At first glance, some people may think "oh yeah cool stars and galaxies or whatever"

But just look at it. It's massive. Each dot of light in this image is a galaxy. Each galaxy is full of hundreds of thousands of millions of stars. Isn't it possible that just one of these galaxies with it's millions of stars could hold at least one other planet that has life on it?

And to think this image was most likely focused and taken in a small patch of the universe. I believe life is brimming and thriving all around us, we're just so insignificant no one has seen us yet because we're either really common or just happen to be located in a boring part of the universe that no one has cared to venture in yet.

It really makes you laugh looking at all the politicians and greedy corporations across the world that squabble with each other and waste time on war and greed instead of exploring the cosmos and making a good name for humanity. They value money more than human life. The time to venture out is now, it's a shame some people can't see it.

If a planet is lifeless, like say Mars, and we seed it with life and biodiversity, is that destruction?

http://www.skyandtelescope.com/online-gallery/nebula-and-galaxy-pictures/

Most amateur star-gazers use consumer cameras, so yeah, these tend to be reliable in terms of color.

 

I sometimes forget that we live in the age where technology that was limited to state-sponsored research teams can now be purchased on Amazon with free delivery. Good call on that. Amateur photography is indeed the correct answer to the original question of, "Where can one find images that aren't artificially colored."

 

Can't wait for amateur space telescopes/probes to become a thing.

So the colors are real?........you mean if i bought a telescope i can see sh*t like that?

1) Yes. 2) Probably not...

 

Space is rather colorful. Problem is, it's dim. Very, very dim. To see the colors you need to do one of two things. Either get a really, really big telescope, or do what most amateur sky photographers do. Take lots and lots of pictures with long exposure, then combine them in software to get one mega-long exposure picture.

 

There are at least a few objects where you can see real color with a decent enough telescope, though. Saturn's rings are visible even with a small telescope or good binoculars, but with some of the larger amateur telescopes you can actually see color on them. Orion's belt nebula is in similar category. There are probably a few others I'm not thinking of right now.

 

 

And I think I see where some of the misunderstanding from earlier came from. When I said that NASA's etc pictures aren't real color, I didn't mean to imply that what they are looking at isn't colorful. They just use filters that tend to use different wavelengths than these that our eyes are sensitive to. So they get a different set of colors that eyes would see. That doesn't mean that color is entirely made up. Nonetheless, they also deal with the problem of very dim sources, so they too use software to correct for it. Most pictures made by Hubble are effectively a huge number of images combined into a single image with super-long exposure. That's what allows you to collect enough light to discriminate colors.
