Recorded May 7, 2014.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- The Kepler Space Craft has found tiny regular dips in light from a star which is about 500 light years away in the constellation of Cygnus. The dips in brightness come about when planets pass between their star and the Earth. This particular star has at least 5 planets. One of them is named Kepler-186f.

- The asteroid Psyche is named for a Greek mythological figure. It  was discovered in 1852 as a moving point of light in the night sky. The size and mass of Psyche suggest that it is dense enough to consist largely of iron.
