Orbiting at outskirts of the solar system some three billion miles from Earth, Pluto remains shrouded in mystery.
Using data from the Hubble telescope, SETI scientists spotted a fifth moon orbiting the icy dwarf planet Pluto.
Long considered a planet, Pluto was reclassified as a 'dwarf planet' in 2006 by the International Astronomical Union. Will the discovery of a fifth moon prompt astronomers to reconsider?
Pluto's newly discovered fifth moon could mean more debris surrounding the icy dwarf planet, which could pose a hazard for NASA's New Horizons spacecraft, which was launched in 2006 with the aim of mapping Pluto's surface.
Scientists examining data from NASA's Hubble Space Telescope have spotted a fifth moon orbiting Pluto. The moon is currently labeled S/2012 (134340) 1, a monicker that could probably be improved.
Almost exactly a year after it spotted a fourth moon orbiting the icy dwarf planet, the Hubble Space Telescope has detected a fifth one.
In an effort to rescue planetary science projects amid budget cuts, scientists in Florida are holding bake sales and car washes to sway legislators to protect NASA's budget.
The humongous asteroid Vesta is actually a protoplanet left over from the early days of our solar system, new observations from a NASA space probe suggest.
The two-stage suborbital rocket was part of a NASA-funded study into how the northern lights can affect signals from GPS satellites and other spacecraft.
NASA's IBEX spacecraft has snagged atoms that came from outside our solar system. Interstellar space includes the raw material that becomes new stars, planets, and organic life.
