Manoj Kaplinghat
Professor of Physics & Astronomy
UCI Observatory
Intended Audience: 
Open to public: 

Join us on July 27, 2013, to explore the night sky from the UCI Observatory. A short lecture entitled, The Biggest Lenses in the Universe: Bending of Light by Gravity, will be presented by Professor Manoj Kaplinghat. Einstein's theory of gravity predicts that light from the distant universe should be bent by intervening matter. This implies that one galaxy can act like a lens for another behind it, an effect that has now been observed! This talk will show pictures of such lensing events and provide a glimpse into why astronomers are excited about using this phenomenon as a way to learn about the distant Universe.

Come and use our telescopes to see stunning views of Saturn and its moons and rings, open star clusters M11 and M16, the Ring and Eagle Nebulae and the famous double star Alberio. Learn to use a night sky map to locate your favorite constellations.

Visitor Nights are open to the Friends of the UCI Observatory and to the public. We thank the Friends of the UCI Observatory for the financial support which enables the UCI Observatory to provide Visitor Nights and activities to the community.
