Latest Gas giant Stories
Our solar system might have been a vastly different place before Jupiter arrived, according to a new Proceedings of the National Academy of Sciences that suggests that the gas giant may have destroyed an entire generation of inner planets before entering its current orbit.
Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus.
Using observations from the NASA’s Hubble Space Telescope, a team of astronomers has managed to create the most detailed map ever of an exoplanet’s air temperature and water vapor, officials from the US space agency announced Thursday.
In a feat of long-distance detection, astronomers led by experts at the University of Maryland have found water vapor in the atmosphere of a Neptune-sized planet nearly 729 trillion miles from
Astronomers using data from three of NASA's space telescopes -- Hubble, Spitzer and Kepler -- have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system.
New evidence from Cornell University reveals that "hot Jupiters," or large gaseous exoplanets, can cause their host stars to wobble as the planets wend their way through their own solar systems to snuggle up against their suns.
Using the largest laser in the world, scientists working at the Lawrence Livermore National Laboratory successfully compressed diamond to core pressures comparable to those found on Jupiter and Saturn, according to research appearing in the journal Nature.
Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets by crushing diamond samples using the world's most powerful
The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream.
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 -- 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...
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...
