Color does not change in space, because the wavelengths remain the same. Although you can see all the colors of the rainbow, plus every color mixture from those colors, you only have three color detectors in your eyes. These color detectors, called cones, have a preference for a particular type of light.

These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.

Is Earth a star?

The Earth is an example of a planet and orbits the sun, which is a star. A star is usually defined as a body of gas which is large enough and dense enough that the heat and crushing pressure at its center produces nuclear fusion. This is a fancy way of saying that it glows or burns, like our sun.
