Well light wise the highest category would be blue giants, red giants, and super red giants.
Stars get light by the air.
The heat and the light in stars is the same thermal nuclear fission that our Sun (a star) produces.
yes stars produce light in the night like the moon. and the sun produces light and heat for the morning
Yes, it is as it produces light from electricity. As said in http://www.schoolsobservatory.org.uk/astro/stars/lumin.shtml
All stars produce light rather than reflecting light.
Incandescent
Light pollution sometimes. But most time it produces the light that emits in a better way.
other stars , nebulous , and galaxies
No. Every star you see produces its own light, just as the sun does. Which isn't surprising when you recall that the sun is a star.
Stars play a variety of roles. First and foremost, the sun is a star. It provides the heat and light necessary for life of Earth. Stars also create most of the elements we find. Before stars started forming all matter in the universe consisted of hydrogen, helium, and trace amounts of lithium. All other elements have since been made in the thermonuclear furnaces of stars.

The heat and light emitted from stars is due to the nuclear fusion within their cores. Stars are so massive that their gravity crushes atoms so close together that their nuclei begin to snap together, releasing loads of energy in the form of light.
