Success! New Horizons Team Sees Occultation by 2014 MU69

July 19, 2017

On July 17, a primitive solar system object that’s more than 6.5 billion kilometers away passed in front of a distant star as seen from Earth. Twenty-four telescopes and dozens of astronomers, including UVA faculty, staff, and students, were deployed by the New Horizons team to a remote part of Argentina in an effort to catch the shadow of the object - an event that's known as an occulation. Several telescopes, including one operated by UVA astronomer Anne Verbiscer, were in precisely the right place at the right time to catch its fleeting shadow.

2014 MU69 is the target of a January 1, 2019 flyby by the New Horizons spacecraft, which encountered Pluto in the summer of 2015. UVA Astronomers Mike Skrutskie and Matt Nelson led the development of three fast and precisely timed telescope imaging systems and recruited and trained several UVA undergraduates to take part in three opportunities this summer to see occultations by 2014 MU69.
