Latest Exoplanetology Stories
The internationally operated Gemini Observatory has announced the start-up of its new Gemini Planet Imager (GPI), a device designed to capture images of planets outside our solar system and probe their atmospheres.
A new discovery, made possible by an international team of astronomers, has located the first confirmed Earth-mass planet occulting, that is -- passing in front of -- its host star.
NASA’s Kepler spacecraft team reported details about five new rocky planets on Monday at the American Astronomical Society meeting in Washington.
A previously-discovered alien world that has an atmosphere that seems to be made up entirely of water vapor or some form of heavy molecule has now been discovered to be very cloudy.
A new technique developed by a team at MIT could help scientists determine the mass of exoplanets, using just their transmission spectra.
University of Arizona astronomers are scratching their heads after discovering the most distant orbiting planet to date which is throwing a wrench in planet formation theories.
A census of planets outside our solar system pierces the haze surrounding five "hot Jupiters" to find conclusive signs of atmospheric water. College
Two teams of scientists have discovered faint signatures of water in the atmospheres of five exoplanets. This is the first study to conclusively measure and compare the profiles and intensities of these signatures on multiple worlds.
Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
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...
