Why is the sun not shining in space?

Rest space is empty. The astroid, plants and planet’s moon shines by the photons released from the Sun(i.e light particles). As there is nothing else in space to shine, hence we never see the Sun’s light.

Where does light come from in the universe?

It comes from giant clouds of dust, cool red stars and even planets. On Earth, it comes from anything that’s warm, including living things, like you! Visible light is a very narrow region of the spectrum. Hot objects like stars emit a lot of visible light.

Why is space black but the sky is blue?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

Why is space cold?

The reason outer space is so cold is because cold is what you get when there is no source of heat nearby. Objects in space cannot cool off by thermal conduction or convection, but they can cool off by radiating infrared light. All objects do this, and they radiate more the hotter they get.

Can there be light without the Sun?

Yes, light can and does exist without the sun and other stars. Light comes from photons interacting with the electromagnetic field.

How is light created in the Sun?

Deep in the sun’s fiery core, atoms fuse and create light. That interaction is called fusion, and it naturally occurs when two atoms are heated and compressed so intensely that their nuclei merge into a new element.

Could the sun light up the universe?

It would be impossible for the sun to light up the universe, simply because for most of the universe, there’s nothing to light up. There are two types of light that we can see, direct light and reflected light. Direct light is light entering our eyes from a source, and we see all of the light in that case.

Why doesn’t the sun illuminate space?

So, if by illumination you mean “light up something so it is visible” then space is not illuminated simply because it is not a thing that can be lit up. But if by illumination you mean filling a space with electromagnetic radiation, then the sun does illuminate space.

How do we infer that the Sun emits light?

We infer that the sun emits light because we can see, during the day, that is. We infer that the sun is doing its job when we look at Saturn, or Jupiter, or our own moon for that matter. We see the light reflected into our eyes from the moon, and assume that those rays were originally from the sun.

Why can’t we see the photons emitted from the Sun?

We can not see the photons being emitted from the sun unless we look directly into it. This is why space is dark; it’s like turning on a flashlight in a room with no dust and no wall to project it’s light beam on. We infer that the sun emits light because we can see, during the day, that is.
