Latest Exoplanetology Stories
After 10 years of orbiting the sun, the Spitzer Space Telescope has been repurposed to hunt for exoplanets outside of our solar system.
Scientists are working on new tools to help detect whether or not life exists on planets far away from our solar system.
The search for a habitable planet beyond Earth is on. And with new techniques emerging, we are able to characterize the atmospheres of these planets more fully.
NASA's Open Source Differential Photometry Code for Amateur Astronomy Research (OSCAAR) program will allow amateur astronomers to help the space agency hunt down exoplanets.
In an effort to search out other worlds, astronomers from the SEEDS project have turned their attention to a somewhat unusual source - a young star known as Ry Tau (Tauri) located some 460 light-years from Earth.
Researchers at Vanderbilt University have found a clever, simple way to accurately estimate stellar gravity using the star's flickering variations of light.
A team of astronomers say free-floating planets can be born freely, outside of an existing solar system -- a discovery that contradicts previous beliefs they must be ejected from host systems.
Scientists from MIT have discovered an exoplanet 700 light-years away that fully orbits its host star every 8.5 hours, noting it has one of the shortest orbital periods ever detected.
The number of exoplanets discovered by astronomers since the beginning of the Space Age some five decades ago suggests there are possibly over 100 billion such worlds outside our solar system, according to one Caltech astronomer involved with NASA’s Kepler mission.
After spending several months attempting to restore the Kepler Space Telescope to full working order, NASA announced on Thursday it was throwing in the towel – though the observatory could continue to function in a somewhat limited capacity.
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...
