If you mean why can’t you see the illumination from the sun if you’re not looking at it that’s because there’s no atmosphere in space to scatter the light. Yes sun is visible in other planets but like earth. As on earth it is visible after ~12 hrs.
Q. Why was Eric using cosmos?
Eric had a computer named Cosmos. Cosmos was the world’s most powerful computer. Cosmos could show many different places and things in space, like stars and comets. It could even send Eric and Annie to space!

Q. Is the cosmos infinite?
Does the cosmos go on forever, or is outer space finite? The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
Q. Why are there no stars in space?
Why can’t we see stars in the pictures of spacewalking or moonwalking astronauts? The stars aren’t visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
Q. Why is the sky black in space?
Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.
Q. Why is the sun so hot but it’s cold in space?
The radiation waves excite molecules they come in contact with, causing them to heat up. This is how heat travels from the sun to Earth, but the catch is that radiation only heats molecules and matter that are directly in its path. Everything else stays chilly.
Q. Why do we age differently in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
