(PhysOrg.com) -- A mysterious planet-like object orbiting a not-quite-starlike "brown dwarf" is the most recent enigma discovered by astronomers with their ever-more powerful telescopes. Kamen Todorov, a graduate student at Penn State University, and a team of co-investigators including Kevin Luhman, assistant professor of astronomy and astrophysics at Penn State, used the keen eyesight of the Hubble Space Telescope and the Gemini observatory to directly image the planet-like object. The team's discovery, which resulted from a survey of 32 brown dwarfs in the Taurus star-forming region, will be published in the Astrophysical Journal.
