My thread title may be a little hard to understand, so i will explain.
A few months ago i saw a website which was dealing with the enormity of space. It showed a simple picture of space and in it you could see thousands of stars.
But then the webpage went on to say “Lets now focus on a tiny, supposedly blank area of this picture and look further”.
It then highlighted an area of about 1 square centimetre and showed all the galaxies that were contained within that small area of the original picture.
I’ve tried and tried to find this picture/website but to no avail.
Does anyone have any idea what I’m talking about?
is the picture you’re talking about - if I remember correctly. I can’t find the link to how this looks empty to the naked eye, but I remember this as that picture…I might be wrong. Memory is never 100%
There’s no stereoscopic vision required for the effect they use — the 3D effect is created solely by the motion of the “camera”. If you want to complain about something, I suppose you could complain about how the camera is moving many skillions of times faster than light, or how the further galaxies don’t look like that any more because of the light travel time. But you could equally well justify these as “artistic license” — it’s not really meant to be scientifically accurate so much as awe-inspiring, and that’s as may be.
Pretty much every astronomical picture you ever see is false color, but when it’s a visible light image, the false colors are usually chosen in such a way as to approximate the true color. The way you get color in an astronomical image at all is to pass the light through various filters before the detector, produce an image for each filter, and then combine them. But the filters are chosen based on what’s scientifically interesting (usually particular spectral lines of various elements), which does not correspond to the response of the color receptors in our eyes.
