Review of Short Phrases and Links

    This Review contains major "Extrasolar Planets"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Extrasolar planets were discovered orbiting the red dwarf Gliese 581 in 2005, about the mass of Neptune, or sixteen Earth masses. (Web site)
  2. For extrasolar planets, the plane, known as the sky plane or plane of the sky, is the plane of the observer's line of sight from Earth.
  3. Although extrasolar planets were long posited, no planets orbiting main sequence stars were discovered until the 1990s. (Web site)

Geoffrey Marcy

  1. She is also a member of the planet search team led by Geoffrey Marcy looking for extrasolar planets.

Beginning

  1. We are beginning to find that many stars besides the sun harbor their own planets, called extrasolar planets. (Web site)

Visit

  1. For more information on extrasolar planets, visit the authors' site. (Web site)

Patterns

  1. In trolling for ideas, I often go to the Extrasolar Planets Encyclopaedia and comb through the tables, looking for patterns or analogies.

Vast Majority

  1. The vast majority of the presently known extrasolar planets lie in elliptical orbits, which would preclude the existence of habitable terrestrial planets. (Web site)
  2. At the moment, however, the vast majority of known extrasolar planets have only been detected through indirect methods. (Web site)

Eccentric

  1. The majority of the extrasolar planets found to date are in an elongated, or "eccentric," orbit.

Space Telescope

  1. More detailed observation of extrasolar planets will require a new generation of instruments, including space telescope s.

Planetary

  1. Astronomers search for extrasolar planets with the Hubble Space Telescope by looking for planetary "shadows" passing in front of stars.

Terrestrial Planets

  1. As of May 2010, there are 453 known extrasolar planets, ranging from the size of gas giants larger than Jupiter to that of terrestrial planets.
  2. As of September 2008, there are known extrasolar planets, ranging from the size of gas giants to that of terrestrial planets. (Web site)

First

  1. Aleksander Wolszczan — discovered first extrasolar planets, pulsar planets, 'solar system', pulsar planetary system.

Finding

  1. The planet-search team, which is supported by NSF and NASA, has been instrumental in finding a majority of the extrasolar planets. (Web site)

Searching

  1. COROT (launched December 2006) and Kepler (launched March 2009) are the two currently active space missions dedicated to searching for extrasolar planets. (Web site)

Search

  1. The star is one of 100 that the scientists have targeted since 1987 in their search for evidence of extrasolar planets. (Web site)
  2. Astronomers also search for extrasolar planets that would be conducive to life. (Web site)
  3. In addition, a series of major web sites dealing with the search for extrasolar planets are listed. (Web site)

Wobble

  1. Marcy and others detect extrasolar planets - most often by a wobble they induce in their host stars. (Web site)

Discovery

  1. When it was announced, the discovery represented one of the first direct images of light emitted from extrasolar planets. (Web site)
  2. Since 1992, and the discovery of hundreds of extrasolar planets, scientists are beginning to observe similar features across the galaxy. (Web site)
  3. The discovery of extrasolar planets raises the question of whether they support extraterrestrial life. (Web site)

Solar System

  1. Other than the Sun, no objects of such mass exist in the Solar System; however a number of extrasolar planets lie at that threshold.

Milky Way Galaxy

  1. Astronomy Online - Gives overview of the solar system, the Milky Way galaxy, extrasolar planets, cosmology and astrophotography.

Modifications

  1. The next IAU conference is not until 2009, when modifications could be made to the IAU definition, also possibly including extrasolar planets.

Planets Orbiting

  1. Based on studies of extrasolar planets, metal-rich stars are more likely to have planets orbiting around them. (Web site)

Orbiting

  1. The first ever detected extrasolar planets were found orbiting a millisecond pulsar in 1990, by Aleksander Wolszczan. (Web site)
  2. In 1995, several of these extrasolar planets were discovered orbiting stars similar to our Sun. (Web site)

Ground-Based Telescopes

  1. This "wobbling" can be observed by ground-based telescopes and alert researchers to the existence of extrasolar planets.

Earth

  1. NASA's future Terrestrial Planet Finder coronagraph, set to launch in 2016, will be able to directly image extrasolar planets as small as Earth. (Web site)
  2. Finding extrasolar planets has taken a long time because detecting them from Earth, even using current technology, is extremely difficult. (Web site)

Transits

  1. In recent years the discovery of extrasolar planets has excited interest in the possibility of detecting their transits across their own stellar primaries. (Web site)

Space Telescopes

  1. More detailed observation of extrasolar planets will require a new generation of instruments, including space telescopes.

Astronomers

  1. The discoveries by Marcy and his team have allowed astronomers to study the masses, radii, and orbits of a diverse array of extrasolar planets.
  2. For the first time, astronomers have measured light emitted from extrasolar planets around sun-like stars using ground-based telescopes.
  3. As the number of known extrasolar planets continues to grow, astronomers are beginning to see patterns in their characteristics.

Planetary Systems

  1. A decade later the number of known extrasolar planets had surpassed 400, and it was estimated that 40% of sunlike stars had planetary systems. (Web site)

Planet

  1. The discovery of extrasolar planets led to another ambiguity in defining a planet; the point at which a planet becomes a star.
  2. In addition, extrasolar planets can be detected by measuring the variance in a star's apparent luminosity, as a planet passes in front of it (see eclipse). (Web site)

Planets

  1. Discoveries of extrasolar planets have shown a correlation between the presence of such planets and a relatively high metallicity of the parent star.
  2. These planets belong to a class of extrasolar planets called hot Jupiters — giants that sit scorchingly close to their stars.
  3. Indeed, as the first extrasolar planets were found, their eccentric orbits caused some to doubt that they are really "planets". (Web site)
