Celebrating the 50th Anniversay of the Planetarium Lecture Series

We are lighting up the night in our cities and towns at faster rates then ever.  Light pollution is light from artificial lights at night that escape upward and sideways creating glare, light trespass and sky glow.  This light creates a perpetual twilight glow in the sky that never gets dark and washes out the wonder of the stars and Milky Way.  Before the introduction of electric lights in the late 19th century our ancestors could see the splendour of the night sky from which we developed rich star lore and the science of astronomy.  In this talk, we see how light pollution happens. How it interferes with astronomical research, its effect on flora and fauna and us.  We need light at night for safety, amenity and cultural activities.  We will see, however, that still we can protect the night sky, bring back the stars and persevere, even improve our nightscape environment at the same time.

*This event is aimed for audiences 16 and above.
