For the first time ever, scientists have found complex organic molecules in a proplanetary disk around a young star, and this is GREAT news for alien life.

Gas giants surviving their death spiral formation has had scientists puzzled for many moons, but new research suggests it's heat that aids their survival.

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets Jupiter and Saturn are more problematic for planetary scientists, as they both lack measureable solid surfaces and are covered by thick layers of clouds, foiling direct visual measurements by space probes. Saturn has presented an even greater challenge to scientists, as different parts of this...

Good news! Experts have analyzed thousands of exoplanets in our galaxy and the calculations show that billions of those stars could have planets in the habitable zone.

NASA’s planet-hunting Kepler spacecraft, which is responsible for discovering more than half of all known planets located beyond our solar system, celebrated its sixth birthday on Saturday, and we thought it would be a good time to take a look back its greatest achievements.

Science fiction fans might remember the dual-star sunset of the first Star Wars film, and while that might seem a little exotic, NASA has reported the discovery of a planet in four-star system called 30 Ari, the second such system ever found.

We may not yet be able to assume that intelligent-life exists on other planets, but a team of Australian scientists are confident there are plenty of planets within our galaxy capable of supporting it--hundreds of billions of “Earth-like” planets, in fact.

Scientists use laser-driving compression experiments (cool) to recreate the planetary formation process (even cooler).

On Tuesday, researchers working with data from NASA's Kepler space telescope announced the discovery of eight new ‘exoplanets’ located in the Goldilocks zone at the annual meeting of the American Astronomical Society.

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Solar Nebula -- In astronomy, the solar nebula is the gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed...

Extrasolar Planet

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...
