The Blanco reflector telescope at Cerro Tololo in Chile has detected a ‘distant dwarf’ planet observers are calling “DeeDee.”
It was discovered during the “Dark Energy Survey” of 12% of the sky looking for dark energy sources. “DeeDee” was slowly moving through the telescope’s field of view.
Further observations with the Atacama Large Millimeter/Submillimeter array, also in Chile, indicate it’s spherical in shape, about 635 kms across, and three times Pluto’s distance from the sun.
Curiosity Stream’s New Program “Miniverse” features Physicist Michio Kaku(City University of New York), Laura Danley (Curator of Griffith Observatory in LA), and Dr. Pitts conducting a mini-tour of the solar system with Canadian astronaut Chris Hadfield.
Another reminder; amateur astronomers are the stars this Friday night as they bring their knowledge and equipment to a neighborhood near you during the City Astronomy Night; one of the signature events of the Philadelphia Science Festival.
