Most of these Jupiter-size "rogue planets" probably have no parent star. But these worlds might be more than science fiction. Sifting through data on the more than 4,100 confirmed alien worlds, scientists apply sophisticated computer modeling techniques to tease out the colors, light, sunrise and sunsets we might encounter if we could pay them a visit. Rogue planets are the drifters of the galaxy, wandering interstellar space alone. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system. Where the Nightlife Never Ends Discovered in October 2013 using direct imaging, PSO J318.5-22 belongs to a special class of planets called rogue, or free-floating, planets. Giant 'Rogue' Worlds Are Less Common Than Scientists Thought.

Answering them will set a boundary between objects that form like stars, which are born out of gravitationally collapsing clouds of gas and dust, and those that form like planets, which are created when gas and dust clump together in a disk around a young star. When NASA’s James Webb Space Telescope launches in 2021, it will shed light on these questions. The program's primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life. May 18, 2011: Astronomers have discovered a new class of Jupiter-sized planets floating alone in the dark of space, away from the light of a star.The team believes these lone worlds are probably outcasts from developing planetary systems and, moreover, they could be twice as numerous as the stars themselves. Wandering alone in the galaxy, they do not orbit a parent star. Some of the planets discovered around stars in our own galaxy could be very similar to arid Tatooine, watery Scarif and even frozen Hoth, according to NASA scientists. NASA’s Exoplanet Exploration Program, the search for planets and life beyond our solar system. Overview. Exoplanet Exploration Program NASA's science, technology and mission management office for the exploration of exoplanets. A rogue, planet-size object 20 light-years away from Earth has stunned astronomers with its incredibly powerful magnetic field. They likely outnumber "normal" alien planets with obvious host stars by … In the "Star Wars" universe, ice, ocean and desert planets burst from the darkness as your ship drops out of light speed.
