2014-02-12 15:57:52

[ Watch the Video: Rotating Globe of Ganymede Geology ] Lee Rannals for redOrbit.com - Your Universe Online Scientists, led by Geoffrey Collins, of Wheaton College, have produced the first global geological map of Jupiter’s largest moon. The map, now published by the USGS as a global map, combines images of Ganymede taken by NASA's Voyager 1 and 2 spacecraft and Galileo orbiter. It is the first global, geologic map of Jupiter’s seventh moon, providing the geologic character of...

Scientists have studied a visual illusion first discovered by Galileo Galilei, and found that it occurs because of the surprising way our eyes see lightness and darkness in the world. Their results advance our understanding of how our brains are wired for seeing white versus black objects. The work was done by Jens Kremkow and collaborators in the laboratories of Jose Manuel Alonso and Qasim Zaidi at the State University of New York College of Optometry. It will be published on February 10 of...

[ Watch the Video: What Happens When Asteroids Go Rogue? ] Lee Rannals for redOrbit.com - Your Universe Online Scientists from MIT and the Paris Observatory claim that rogue asteroids are more common than previously thought. Previously, scientists believed that asteroids were static and remained near the sun. However, observations in the last decade have revealed that asteroids show up in unexpected places in space. “That [theory] has been completely turned on its head,”...

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the more interesting questions in astronomy surrounds how solar system objects actually form. Astronomers are particularly concerned about the boundary between a planet and a star. When examining the objects in our own solar neighborhood, the question seems trivial – the Sun dominates the mass of our system, while even the largest planet, Jupiter, is dwarfed by comparison. In other parts of the galaxy, stars exist that...

[ Watch the Video: Binary Asteroid System Discovered ] Brett Smith for redOrbit.com - Your Universe Online An undergraduate astronomy class for non-astronomy majors at the University of Maryland has made a rare discovery that was completely overlooked by professional scientists: a pair of asteroids that orbit and regularly eclipse each other located in the main asteroid belt between Mars and Jupiter. There are currently fewer than 100 known eclipsing binary asteroids and the...

Storms As Big As Jupiter's 'Great Red Spot' Found On Brown Dwarfs

[ Watch the Video: Torrential Storm Clouds On Brown Dwarfs ] Lee Rannals for redOrbit.com - Your Universe Online Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington. Brown dwarfs are a form of star, but lack the mass to fuse atoms continually to turn themselves into a full-fledged star. The celestial bodies are like a cross between a Jupiter-sized gas planet and a star....

WASHINGTON, Dec. 31, 2013 /PRNewswire-USNewswire/ -- Scientists using NASA's Hubble Space Telescope have characterized the atmospheres of two of the most common type of planets in the Milky Way galaxy and found both may be blanketed with clouds. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The planets are GJ 436b, located 36 light-years from Earth in the constellation Leo, and GJ 1214b, 40 light-years away in the constellation Ophiuchus. Despite numerous efforts,...

Hubble Finds Europa Water Vapor

[ Watch the Video: Europa Shows Evidence Of Liquid Water ] Brett Smith for redOrbit.com - Your Universe Online For years scientists have suspected the presence of liquid water under the surface of Jupiter’s moon Europa. Now, the Hubble Space Telescope has detected evidence of water vapor eruption from the moon’s surface, according to a new report published in Science Express on Thursday. The space agency is looking to observations from other sources to confirm Hubble’s initial...

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
