Astronomy can be a cosmic detective story, and our enduring fascination with the solar system's mysterious hinterland of small icy objects in the Kuiper belt is no exception.
In fact, as wonderfully detailed by Mike Brown, professor of planetary astronomy at the California Institute of Technology (Caltech), his detective work focuses on the growing population of dwarf planet discoveries in the Kuiper belt, revealing the frigid region used to be a pretty violent place.
Brown took a retrospective look at his research during the W. M. Keck Observatory 20th Anniversary Science Meeting at The Fairmont Orchid, Hawaii, the Big Island, on Thursday. Brown is famously known as the "Pluto Killer" - he discovered the dwarf planet Eris in 2005 that, ultimately, led to Pluto being reclassified by the International Astronomical Union (IAU) in 2006. The fascinating story is revealed in his best-selling book, "How I Killed Pluto and Why It Had It Coming."

Although each Kuiper belt object its own unique story of discovery, Brown discussed the detection and investigation of the oddball dwarf planet (136108) Haumea - a world approximately a third of the mass of Pluto. Originally discovered by Brown's Caltech team using the Palomar Observatory in 2004, key observations were carried out with the Keck Observatory telescopes atop Mauna Kea, Hawaii. "We named the object Haumea in honor of the work done at Keck," said Brown. In Hawaiian mythology, Haumea is the goddess of fertility and childbirth.
