WASHINGTON, March 2, 2015 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft has returned new images captured on approach to its historic orbit insertion at the dwarf planet Ceres.
A bright spot previously detected on the dwarf planet Ceres appears to have a somewhat dimmer companion, and NASA remain unable to explain exactly what these unusual lights are.
Craters and mysterious bright spots are beginning to pop out in the latest images of Ceres from NASA's Dawn spacecraft. These images, taken Feb. 12 at a distance of 52,000 miles (83,000 kilometers) from the dwarf planet, pose intriguing questions for the science team to explore as the spacecraft nears its destination.
WASHINGTON, Jan. 27, 2015 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft has returned the sharpest images ever seen of the dwarf planet Ceres.
NASA's Dawn spacecraft is nearing Ceres, and new images show a puzzling white spot on its surface.
Vesta, the propoplanet visited by NASA’s Dawn spacecraft from 2011 through 2013, may have once been home to short-lived flows of water-mobilized material – a discovery which could have tremendous implications for the field of planetary science, according to the US space agency.
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.
On January 26, 2015, the 0.6 mile-wide asteroid 2004 BL86 will pass within 745,000 miles of Earth. So...there's not much to worry about. Just get your telescopes ready.
Rather than being planetary building blocks, asteroids and meteorites may actually be the byproducts of planetary collisions occurring billions of years ago, according to researchers from MIT and Purdue University.
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.
Johann Daniel Titius was born on January 2, 1729 in Konitz, Royal Prussia. He was a professor at Wittenberg. He is most famous for the Titius-Bode law, which helped him find the existence of a minor planet at 2.8 AU from the sun in 1766. The planet was later named Ceres. Titius died in Wittenberg on December 11, 1796. To his honor, the Titius asteroid in 1998 and the Titius lunar crater are named after him.
Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...
Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...
Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...
The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
