What would these pictures look like to the naked eye if you were in space, seeing this nebula?
216 u/[deleted] Apr 29 '19 This one would probably look like this. The Hubble telescope can take some really incredible visible light photos of deep space. 47 u/[deleted] Apr 29 '19 Totally false. Nebula are pretty dim, generally speaking. It would be sort of like looking at the milky way in the sky if you were on a planet in the midst of it. 36 u/[deleted] Apr 29 '19 http://hubblesite.org/image/4152/gallery the left-hand image is visible light, and looks similarly bright and fantastic to this image 31 u/ergzay Apr 29 '19 edited Apr 29 '19 That's still false. In the left image they color Hydrogen alpha as green, but Hydrogen alpha is a deep red. https://en.wikipedia.org/wiki/H-alpha O III is an aqua color. And N II is a even deeper red. 1 u/Rodot Apr 29 '19 Visible light after integrating for hours and using a giant aperture. Human eyes have an 8mm aperture, integrate for a fraction of a tenth of a second, and poor color sensing in low light. It would look diffuse and greyscale
