Latest Dwarf planet Stories
New images of Ceres captured by NASA’s Dawn spacecraft during its approach to the dwarf planet are the best yet obtained by the spacecraft, and appear to show evidence of craters as well as a mysterious white spot first discovered by the Hubble Space Telescope in 2003.
After a journey of more than eight years, NASA’s New Horizons spacecraft has finally entered the first of several planned approach phases around Pluto, and these will culminate with a historic first-ever flyby of the dwarf planet this summer.
While some astronomers are looking for the existence of planets light years away from Earth, a team of Spanish researchers has suggested there could be at least two planets that have yet to be discovered in our very own Solar System.
After a journey that lasted more than seven years, NASA’s Dawn spacecraft has entered its approach phase around Ceres as it prepares to become the first spacecraft ever to visit the Texas-sized dwarf planet.
The Dawn spacecraft has delivered a glimpse of Ceres, the largest body in the main asteroid belt, in a new image taken 740,000 miles (1.2 million kilometers) from the dwarf planet. This is Dawn's best image yet of Ceres as the spacecraft makes its way toward this unexplored world.
Three new Kuiper Belt objects that could possibly be visited by the New Horizons spacecraft have been uncovered by the Hubble Space Telescope.
Pluto may no longer be a planet in the eyes of the International Astronomical Union, but as a recent debate hosted by the Harvard-Smithsonian Center for Astrophysics revealed, not everyone agrees with the official assessment that led to its 2006 demotion.
In just over a year, the New Horizons spacecraft will fly past Pluto, giving us our first detailed look at the dwarf planet.
Scientists using the Very Large Telescope (VLT) created the world’s first map of the weather on the surface of a brown dwarf.
Uranus' moon Titania -- Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus, Oberon, Titania, Ariel and Umbriel, were given by John Herschel, the son of William. Titania was named after Titania, the Queen of the Faeries in A Midsummer Night's Dream. Titania is composed of roughly 50% water...
Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
