Yes, Earth does give off light, but not in the way we usually think of it.

Here's a breakdown:

* Visible Light: Earth doesn't produce its own visible light like the Sun. We see Earth because sunlight reflects off its surface.

* Infrared Radiation: Earth emits infrared radiation, which is a form of heat. This is why we can detect Earth from space using infrared telescopes.

* Other Emissions: Earth also emits very faint amounts of other types of light, such as radio waves and X-rays, which are generated by various natural processes.

So, while Earth doesn't shine with visible light, it does emit a variety of other forms of light that can be detected from space.
