Hubble Captures Planet Formation 7.5 Billion Miles From Host Star
2013-06-13 15:09:54

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using NASA's Hubble Space Telescope say they have discovered evidence of a planet forming 7.5 billion miles away from its host star. The exoplanet is under construction about 176 light-years away from Earth in the constellation Hydra the Sea Serpent. The suspected planet is orbiting the diminutive red dwarf TW Hydrae. "It's so intriguing to see a system like this," said John Debes of the Space Telescope Science...

Researchers Look At Hot Jupiters And Planetary Migration
2013-06-07 07:20:56

April Flowers for redOrbit.com — Your Universe Online Stars have an alluring pull on the planets that surround them, especially a class of planets known as hot Jupiters. These planets are gas giants that form farther from their stars before migrating inward and heating up. Hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars, as a new study conducted with data from NASA´s Kepler Space Telescope reveals. These planets remain in fairly stable...

Planetary Dance In The Sunset Sky
2013-05-24 04:15:11

[ Watch the Video: ScienceCasts: Sunset Triangle ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Fans of stargazing are in for a treat this weekend. Over the next several days the planets, Venus, Jupiter, and Mercury will approach each other in the fading sunlight to form a triple conjunction — where three bodies appear to converge in the sky. The events will culminate on the evening of the 26th, and will appear to form a triangle just above the horizon....

Charting Massive Winds On Gas Giants Of The Outer Solar System

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Predicting the weather is difficult. With varying pressures, planetary rotation and various other factors, weather systems on Earth border on chaos. But, believe it or not, predicting the weather on the third rock from the sun is rather straightforward compared to predicting the atmospheric motions of the gas giants that lay beyond the asteroid belt. The primary reason is that, unlike Earth, the Jovian worlds do not have...

Cassini Sees Seasonal Plasma Changes On Saturn
2013-05-03 19:11:31

Lee Rannals for redOrbit.com — Your Universe Online NASA's Cassini spacecraft has helped shed light on one way the bubble of charged particles around Saturn changes with the planet's seasons. Earth has a magnetosphere like Saturn, and the latest results may help scientists better understand variations in it and the Van Allen radiation belts, which both affect things from space flight safety to satellite and cell phone communications. Researchers wrote in the Journal of Geophysical...

Researchers Shed Light On Why Saturn Looks So Young
2013-04-30 14:52:47

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online At the dawn of our Solar System the planets were very hot, as the energy from their creation lingered. But over time the planets would cool, becoming darker, only occasionally paused in this process by large impacts or radioactive decay. At least that is what we would expect. A mystery that has puzzled scientists for half a century revolves around the appearance of the planet Saturn. The second largest planet in our Solar...

Meteoroids Slam Into Saturn’s Rings
2013-04-25 15:08:34

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Thursday that its Cassini spacecraft provided the first direct evidence of small meteoroids crashing into Saturn's rings. Previously, scientists had only witnessed impacts on Earth, the moon and Jupiter as they occurred. Studying the impact rate of meteorites outside the Saturnian system helps scientists understand how different planetary systems in our Solar System formed. The meteoroids that impacted Saturn are...

Hubble Provides Great View Of Comet ISON
2013-04-24 08:46:26

[ Watch the Video: ScienceCasts: Comet ISON Meteor Shower ] Lee Rannals for redOrbit.com — Your Universe Online Astronomers have been given the clearest view yet of a comet that is supposed to light up the skies later this year. Comet ISON is expected to create a spectacular show in the night sky in November, and NASA's Hubble Space Telescope has provided scientists with a great preview, months before its premier debut. Comet ISON is a "dirty snowball," meaning it is a...

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...
