How fake are these types of photos of space anyway? I just find it extremely hard to believe that space is actually this cool looking and beautiful. There has to be some trickery or photoshop involved.

Just look up in the sky at night.

Oh wait, you can't because of light pollution. Sucks to be an urbanite subhuman like you, I guess.

Very, astronomers enslave a bunch of graduate students to color in pictures of what they think galaxies look like pixel by pixel, and then once they're done they kill all the slaves by burning them alive in the observatory so no one ever finds out.

They aren't fake dumbass, although when webb or hubble take photos the receive them in the light spectrum and colour them based off the frequency of light.

Specific light frequencies are specific colours.

It isn't. They take "black and white photos" of various light frequencies and then color them and combine into one colorful image. Space doesn't look like that to human eye, but this data isn't faked. It's just represented visually in a pretty but unrealistic way.

Forests, rainbows, etc on Earth look beautiful all the time, why shouldn't outer space have beautiful looking things as well?

I never said the images are not fake. I said that data used to make them is not fake, but it is represented in an unrealistic way.

Humans can't see a lot of light frequencies anon, if they didn't colorise the pictures you wouldn't be able to see them. The objects you see are how they are,they are just coloured so that we are able to see them.

It is like looking through night vision goggles and seeing everything in green. Everything is still how it is, just green.

andromeda is the size of the moon and it can be seen with naked eye. Only you wont see any color

They're "fake" in the sense that to your human eyes the galaxy would just appear white in visible spectra, false colour images are taken in different wavelengths and those different wavelengths are assigned different colours to differentiate between gases and shit, otherwise the picture is just black and white.

>The NASA/ESA Hubble Space Telescope has snapped the best ever image of the Antennae Galaxies. Hubble has released images of these stunning galaxies twice before, once using observations from its Wide Field and Planetary Camera 2 (WFPC2) in 1997, and again in 2006 from the Advanced Camera for Surveys (ACS). Each of Hubble’s images of the Antennae Galaxies has been better than the last, due to upgrades made during the famous servicing missions, the last of which took place in 2009. The galaxies — also known as NGC 4038 and NGC 4039 — are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another. This clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. In wide-field images of the pair the reason for their name becomes clear — far-flung stars and streamers of gas stretch out into space, creating long tidal tails reminiscent of antennae. This new image of the Antennae Galaxies shows obvious signs of chaos. Clouds of gas are seen in bright pink and red, surrounding the bright flashes of blue star-forming regions — some of which are partially obscured by dark patches of dust. The rate of star formation is so high that the Antennae Galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars. This cannot last forever and neither can the separate galaxies; eventually the nuclei will coalesce, and the galaxies will begin their retirement together as one large elliptical galaxy. This image uses visible and near-infrared observations from Hubble’s Wide Field Camera 3 (WFC3), along with some of the previously-released observations from Hubble’s Advanced Camera for Surveys (ACS).
does this answer your question OP?

But you can see them? Just use a telescope, they just aren't very bright in visible light.

[Anonymous No.15118915]

The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14, 2009.

urbanites surrender all sorts of things in order to become urbanites. urban zones have the most polluted air of anywhere in the world, including CO2 levels over twice as high as well as CO pollution with does not occur outside of urban locations. All of that air pollution causes measurably reduced IQ for urbanites, thats why you're moaning and whining like a little bitch about how much you hate where you live, if you had an IQ that wasn't ruined by stewing yourself n a sea of toxic gasses then maybe you'd be bright enough figure a way out of your urban hellhole.

The raw Hubble images, as beamed down from the telescope itself, are black and white. But each image is captured using three different filters: red, green and blue. The Hubble imaging team combines those three images into one, in a Technicolor process pioneered in the 1930s. (The same process occurs in digital SLRs, except that in your camera, it's automatic.)

Why are the original images in black and white? Because if Hubble's eye saw in color, the light detector would have to have red, green and blue elements crammed into the same area, taking away crucial resolving capability. Without those different elements, Hubble can capture images with much more detail.

I do astrophotography. With enough exposure you can get colors like this.

Lol wut? I don't hate where I live, nor did I imply I did.

I'd like to live in some part of the country (UK) but there isn't really anywhere in the UK apart from literally the middle of nowhere where there isn't any light pollution.

And I live in the middle of the UK, it is like 2-300 miles to the nearest place with low light pollution.

not much. just like how computers convert data into an image. telescopes take the data and convert it and stitch together. then they might hire an artist to add color grading like curves and exposure and flares like this one. take a class or something and go on a night with the telescopes to see andromeda galaxy pretty cool.
