Latest Exoplanetology Stories
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.
Scientists debate the criteria for trying to determine what makes a planet habitable and how many exoplanets there are out there.
You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again.
Researchers using new theoretical models have created a new method to simplify the search for Earth-like planets. The new models help rule out the possibility of Earth-like conditions on certain planets outside of our solar system.
New statistical analysis of data obtained by NASA’s now-retired Kepler spacecraft has revealed that one out of every five sun-like stars have at least one Earth-sized planet in the habitable zone.
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...
