2015 is the International Year of Light, as proclaimed by the United Nations General Assembly, and that was the theme in Manoa Sunday, as hundreds turned out for the annual UH Institute for Astronomy open house.

Light-related activities included observing the sun through telescopes, seeing what you look like through an infrared camera, learning about the invisible universe, and using light from distant objects in the universe to learn their composition and temperature.

I just think the diversity is amazing, said parent Lisa Hartwell-Tindle. They have so many cool things here for your kids to learn and all the hands-on stuff is amazing for an almost 5-year-old, and of course, hes only interested in the face paint.

There were also 3D printers, a wind tunnel, air-powered rockets, and a portable planetarium.
