Pluto’s classification as a “dwarf planet” came as a shock to some, but in reality our understanding of Pluto has always been in flux. Pluto is a tiny, distant, icy object, difficult to see even with Hubble’s vision. Join a Hubble astrophysicist as we explore our history with Pluto, from its discovery to the excitement over the upcoming visit by the New Horizons space probe, in Hubble’s Universe Unfiltered.
“Hubble’s Universe” is a recurring broadcast from HubbleSite, online home of the Hubble Space Telescope. Astrophysicist Frank Summers takes viewers on an in-depth tour of the latest Hubble discoveries. Find more episodes at HubbleSite.org.
