ST. LOUIS – Truman State University students and faculty might notice more stars in the sky when they return to campus this fall.

KWMU-FM reports that after four years of research on how artificial light brightens the night sky, scientists are planning to change lighting on campus to direct light away from the sky.

Light pollution prevents people from seeing stars and galaxies and can disrupt sleep patterns.

Truman State gave a researcher a $10,000 grant to install shields on 60 outdoor light fixtures to direct light to the ground and away from the sky. The campus also will replace blue and white bulbs with bulbs that emit warmer colors, like yellow and red.

NASA satellite imagery shows light pollution worldwide has increased over time and scientists say it could get worse.
