Question:

Are there some places in space where it isn't pitch black

When astronauts break through our atmosphere and go into space, the surrounding area is black, everyone knows that. But are there some places in the universe where space appears to be red, blue, white, orange ect.? Like if someone on another planet took their space ship through the atmosphere of their planet to leave the planet, could it appear colored? I'm asking this question because when you look at photos of nebulae the space around the nebula isn't black, it has colored space around it, so if there was a nebula near earth, when astronaughts went into space it wouldn't be black right? It would have some sort of color right?

  1. Astronauts describe space as the blackest black you can imagine.

    many astronomical photographs of gas and nebula are color enhanced.


  2. Yes.  Everywhere.  But it takes a few seconds for your eyes to adjust to the much lower light levels.  It can take 45 minutes for your eyes to fully dark adapt.

    If you were to visit a nebula up close and personal, what would your experience be?  It's a vacuum. And a hard vacuum at that.  Better than in low Earth orbit.  But a nebula that is a light year across with a bit of dust or a hydrogen atom here and there can reflect a huge amount of light.  But from inside it you'll just see a glow all around.  Something like zodiacal light.

    The colors can be real enough.  But without a huge telescope, it's very hard to experience colors from celestial objects.  Astrophography gets around this by taking long exposures.  Your eye can only collect light for about a tenth of a second.  And yet, many (if not most) astronomical images use false color.  They'll take an image with a hydrogen alpha filter, and assign that to the red channel.  Then they might take an image with a sulfur 2 filter and assign that to green.  And finally they'll take an image with an oxygen 3 filter and assign that to blue.  But for example, oxygen 3 is kind of a greenish blue. So the result isn't what your eyes would see.  And on top of that, processing is done to bring out contrasts, so you can get a feeling for what's going on.  Pretty pictures, but nothing you'd see with your eyes.


  3. A vacuum won't return you any colour.  Empty space is black.  Well, really, its colourless, but you'll see it as black because black is a lack of colour.

    If you see astronomical pictures of something other than black, it's being caused either by a lightsource such as a star or, more likely, light reflecting off of or passing through some type of matter.

  4. the sun or places of high energy

  5. The universe s beige if you look at it from the outside in....


  6. If you were in a space ship that was inside a nebula the "sky" would be the color of the nebula - red if a red nebula like the Rosetta nebula.

    There are other colors too.

  7. Maybe so its a whole lot of worlds out there

  8. The area around them appears pitch black because the film used is made to develop things in low light and therefore it makes everything in the background blend in to black. (I don't know if that's exactly why, but I DO know it's because of the film they use)

  9. Only if thre's some object (like a cloud, nebula, debris field, etc) to reflect or generate those colors.  If there's *nothing* there, then... black is the only color to be seen.
