Asteroids Following Jupiter’s Solar Orbit Show Their True Colors
2012-10-16 08:51:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Jovian asteroids that orbit the Sun on the same trajectory as the gas giant Jupiter have been studied more closely by scientists using NASA´s Wide-field Infrared Survey Explorer (WISE). These asteroids travel in packs, like hungry wolves stalking their prey, some racing ahead of the gas giant, while others trail behind. The observations of these Jovian predators are the first detailed look at their true colors. Scientists...

Lost Asteroid Rediscovered By Amateur Astronomer
2012-10-13 05:05:52

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) reports that it has rediscovered an asteroid that was once lost through the agency's space hazards program. Potentially Hazardous Asteroid 2008SE85 was first discovered back in September 2008 by the Catalina Sky Survey, and was observed by a few observatories the following month. However, no one since then has observed the object, and predictions for its current position had become so inaccurate that...

Meteorite Shows Vesta Once Had Active Dynamo
2012-10-12 15:56:02

Lee Rannals for redOrbit.com — Your Universe Online Scientists have determined that the second-most-massive asteroid in the solar system may have once had an active dynamo. A meteorite found in Antarctica believed to be from Vesta holds clues to the asteroid once harboring a molten, swirling mass of conducting fluid generating a magnetic field, or dynamo. Scientists suspect that the composition of asteroids offer information about the diversity of planetary bodies within the...

Asteroid Fragments May Give Insight Into Origins Of Planets

Alan McStravick for redOrbit.com - Your Universe Online The year was 1998. The Red Hot Chili Peppers had just parted ways with Dave Navarro. The world was introduced to Britney Spears. And the movie Armageddon bested all other films at the box office. It seems fitting that the same year that gave us Michael Bay´s fictional interpretation of how we should deal with an asteroid coming towards us would be the same year that the Lincoln Near-Earth Asteroid Research (LINEAR) project...

Olivine Found In Beta Pictoris

April Flowers for redOrbit.com - Your Universe Online European Space Agency's (ESA) Herschel Space Observatory has discovered pristine material that matches comets in our own Solar System in a dust belt around the young star Beta Pictoris. Beta Pictoris is 12 million years old, and resides a short 63 light-years from Earth. A gas giant planet and a dusty debris disc that has the potential to evolve into a torus of icy bodies like those of the Kuiper Belt found outside the orbit of...

Water May Have Been Deposited On Vesta Asteroid Long Ago
2012-09-26 14:42:05

Lee Rannals for redOrbit.com — Your Universe Online Astronomers suggest that water may have been delivered to Vesta through a build-up of small particles during an epoch when the Solar System was rich in dust. The team presented their research at the European Planetary Science Congress in Madrid on Wednesday, offering up a radically different hypothesis from the way in which hydrous materials are deposited on other cosmic objects. Using data from NASA's Dawn mission, the team...

Watch the Video: Hydrogen Hot Spots on Vesta Lee Rannals for redOrbit.com - Your Universe Online According to findings reported in the journal Science, NASA's Dawn spacecraft has revealed signs of hydrated minerals on the giant asteroid Vesta. Dawn did not find actual water ice at Vesta, but it did reveal signs of hydrated minerals delivered by meteorites and dust to the asteroid. "The source of the hydrogen within Vesta's surface appears to be hydrated minerals delivered by...

Momentum Grows for First Private Deep Space Mission to Map the Inner Solar System and Track Asteroids Posing Threats to Earth The world´s first privately funded deep space mission — SENTINEL — received major support this week from prominent members of the business and financial community who joined the B612 Foundation´s Founding Circle. Founding Circle Members not only contribute substantial funding to the mission, but also pledge continued support in multiple areas...

NASA Releases Last Images Of Dawn Spacecraft Visit With Vesta Asteroid
2012-09-12 14:31:54

April Flowers for redOrbit.com - Your Universe Online As NASA's Dawn mission spacecraft speeds away from the giant asteroid Vesta, mission control has released two parting views using images that were among the last taken by Dawn. One set of images is a color-coded relief map of Vesta's northern hemisphere, from the pole to the equator. It incorporates images taken as Dawn began to creep over the high northern latitudes of Vesta. These were dark when Dawn arrived in June 2011. The...

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

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...
