Travelers in the Night - Eps. 255 & 256: Earth-Venus Express & Pale Blue Dot

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. Today's 2 topics: - Carson Fuls discovered 2016 HD3, which will make 53 close approaches to Earth in the next 100 years. - Voyager 1 took the famous "Pale blue dot" photo over 25 years ago. New telescopes will enable us to look for pale blue dots around other stars! A spectrum that includes traces of oxygen would be even better, of course.
