Latest Exoplanetology Stories
Astronomers announced on Monday that they have discovered a new type of planet - a rocky world weighing 17 times as much as Earth.
Life in the universe might be even rarer than we thought.
By studying a hazy sunset on Titan via the Cassini spacecraft, scientists are learning new ways to better understand the atmospheres of exoplanets orbiting distant stars.
Believed to be retired for good after breaking down last year, the Kepler spacecraft has been revived and will be part of a newly-approved NASA mission to seek out new exoplanets while also expanding its role into the realm of astrophysical observations.
Using observations from multiple observation facilities, an international team of astronomers has identified a very unusual planet that takes around 80,000 Earth years to orbit its sun.
Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours.
A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought.
NASA's WISE and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole.
Mysteries of one of the most fascinating nearby planetary systems now have been solved
Researchers searching for planets orbiting around a distant star look for a signature dimming of that star’s light, but what if the distant star suddenly gets a bit brighter?
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...
