Gas Giant Exoplanets Close To Parent Stars
2013-06-28 09:34:28

Results from the Gemini Observatory’s recently completed Planet-Finding Campaign reveal the outlying orbital space around many types of stars is largely devoid of gas-giant planets, which appear to remain close to their parent stars.

Electrifying Exoplanets With Stellar Winds

When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own.

Weather Forecasting For Hot Jupiters

The class of new worlds dubbed as “hot Jupiters” definitely live up to their name, according to new research that has recorded temperatures as high as 2400 degrees Kelvin (or more than 3800 degrees Fahrenheit) on one of these massive, close-orbiting exoplanets.

Charting Massive Winds On Gas Giants Of The Outer Solar System

Predicting the weather is difficult. With varying pressures, the Earth’s rotation, and various other factors, weather systems border on chaos. But, believe it or not, predicting the weather on Earth is rather straightforward compared to predicting the atmospheric motions of the gas giants that lay beyond the asteroid belt.

Hot Jupiters More Nuanced Than Expected
2013-05-07 10:16:25

Scientists working with NASA’s Spitzer Space Telescope have found that exoplanets known as hot Jupiters are not all alike and appear to have a wide range of climates.

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

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.

Exoplanet May Have Formed Through Core Accretion

An international team of astronomers has made the most detailed examination to date of the atmosphere around a Jupiter-like exoplanet using the Keck Observatory, one of the two largest optical telescopes in the world.

Giants Like Jupiter May Have Formed In The Gas Disk Of Young Stars
2013-03-06 06:18:35

New research from Carnegie Institution for Science looks at how gas giants similar to Jupiter and Saturn formed and evolved. Using theoretical modeling, lead researcher Alan Boss provides clues that gas giants may form in the presence of gas disks that surround stars in their infancy.

Planet Forming Gas Streams Revealed
2013-01-02 12:09:51

Astronomers who made observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope are helping to shed light on planet-forming gas streams.

Astronomers Discover Comets Scattered Throughout Planetary Systems

Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...

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...

Gas Giant

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

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...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...
