Magellanic Clouds
In 1959, while serving as a professor of astrophysics at the Case Institute of Technology (renamed Case Western Reserve University in 1967) in Cleveland, Ohio, Blanco discovered an open cluster. It was named Blanco 1 in his honor, and is centered on the blue star Zeta Sculptoris. According to "The Monthly Notices of the Royal Astronomical Society", Blanco 1 exhibits subsolar ratios that are not observed among nearby field stars. Together with his wife Betty, Blanco and Martin McCarthy conducted pioneering research into the stellar population in the central regions of our galaxy, and in the Magellanic Clouds. They discovered the change in the ratio of carbon stars to M-type stars from the nuclear bulge of our galaxy, in relation to both Large Magellanic Clouds and Small Magellanic Clouds.
