Collage Of Radar Images Of Asteroid 2005 WK4
2013-08-16 17:04:11

NASA A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013. The asteroid is between 660 and 980 feet (200 and 300 meters) in diameter; it has a rounded and slightly asymmetric shape. As it rotates, a number of features are evident that suggest the presence of some flat regions and a bulge near the equator. The data were obtained between 12:40 and 7:10...

NASA Asteroid Mining Mission
2013-08-09 12:28:02

[ Watch The Video: OSIRIS-REx Investigates Asteroid Bennu ] Brett Smith for redOrbit.com - Your Universe Online NASA announced yesterday that it will be launching a spacecraft in 2016 with the intent of laying the groundwork for future expeditions to mine asteroids. The space agency added that the mission – dubbed the Origins, Spectral Interpretation, Resource Identification, Security and Regolith Explorer (OSIRIS- REx) – is scheduled to visit the asteroid Bennu and enable...

Graveyard Of Comets Discovered
2013-08-03 07:48:35

Royal Astronomical Society A team of astronomers from the University of Anitoquia, Medellin, Colombia, have discovered a graveyard of comets. The researchers, led by Antioquia astronomer Prof. Ignacio Ferrin, describe how some of these objects, inactive for millions of years, have returned to life leading them to name the group the 'Lazarus comets'. The team published their results in the Oxford University Press journal Monthly Notices of the Royal Astronomical Society. Comets are...

Asteroid Initiative RFI Receives 400+ Responses
2013-07-27 07:19:30

April Flowers for redOrbit.com - Your Universe Online NASA Deputy Administrator Lori Garver announced this week that the agency has received more than 400 responses to its request for information (RFI) on its Asteroid Initiative. "Under our plan, we're increasing the identification, tracking and exploration of asteroids, and the response to this initiative has been gratifying," said Garver, speaking at the Space Frontier Foundation's NewSpace 2013 conference in San Jose, Calif. "The...

Cometary Origins For Most Centaurs: WISE
2013-07-26 04:44:52

April Flowers for redOrbit.com - Your Universe Online The small celestial bodies orbiting between the sun and Jupiter and Neptune are known as centaurs, and their true identity has been one of the enduring mysteries of astrophysics. Previously, scientists have questioned, are they asteroids or comets? A new study, published in the Astrophysical Journal, using observations from NASA's Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. Astronomers have been unsure...

Donald K. Yeomans Receives Carl Sagan Medal For Public Communication

NASA's Jet Propulsion Laboratory For his work making the solar system's nomads of the night sky -- near-Earth objects, asteroids and comets -- tangible and compelling for millions of people, Donald K. Yeomans, the manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, has received the 2013 Carl Sagan Medal from the American Astronomical Society (AAS). The Sagan Medal recognizes a planetary scientist for excellence in public communication....

Asteroid Surface More Unstable Than Previously Thought
2013-07-05 12:02:49

Lee Rannals for redOrbit.com - Your Universe Online An experiment in microgravity has revealed future missions seeking to land on an asteroid may have to watch out for an avalanche. Researchers discovered the rubble and dust covering asteroids and comets could feel changes between particles over much larger distances than on Earth, making these surfaces much less stable than previously thought. "We see examples of force-chains everywhere. When you pick an orange from a pile in a...

Dolores Hill Honored As White House Champion Of Change

University of Arizona University of Arizona researcher Dolores Hill, co-lead of the OSIRIS-REx Target Asteroids! program, has been recognized as one of 12 White House Champions of Change recipients. Hill and her 11 counterparts were selected from a pool of about 1,000 nominations. The group was honored at a ceremony at the White House, which was attended by representatives of the Obama Administration and other honorees' families, friends and colleagues. "It is such an honor to be...

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...

Solar System
2012-10-22 06:09:41

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...
