New Research Suggests Light Pollution Is Worse Than Previously Thought
Light pollution is the phenomenon by which artificial light reduces the amount of visible stars. Recent data suggests light pollution is getting worse.
Could Plants Be Detected on Other Planets?
Plant life on exoplanets could potentially be detected through the amount of infrared radiation that plants reflect back into space.

Why Are Planets Round?
In order for an object to be a planet, one of the defining criteria is that it be spherical. Planets are round due to the force of gravity.
