Jose G. Ortega Castro/UnsplashHow has light pollution obscured the night sky, including the Milky Way? What are the main sources of light pollution in cities? How can shielding lights and using dimming techniques reduce light pollution? Why is it important to use warm-colored lights for our health and the environment? How can we bring back the night sky and see the stars again? How to Reduce Light Pollution and Reclaim the Night Skyby Brad E Tucker, Australian National University.

By Brad E Tucker WHAT is the universe made of? This question has driven astronomers for hundreds of years. For the past quarter of a century, scientists have believed “normal” stuff like atoms and molecules that make up you, me, Earth, and nearly everything we can see only accounts for 5% of the universe. Another 25% is “dark matter”, an unknown substance we can’t see but which we can detect through how it affects normal matter via gravity. The remaining 70% of the cosmos is made of “dark energy”.

Are we alone? This question is nearly as old as humanity itself. Today, this question in astronomy focuses on finding life beyond our planet. Are we, as a species, and as a planet, alone? Or is there life somewhere else? Usually the question inspires visions of weird, green versions of humans. However, life is more than just us: animals, fish, plants and even bacteria are all the kinds of things we seek signs of in space.
