Latest Exoplanetology Stories
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.
NASA will host a news teleconference at 2 p.m. EDT Thursday, Aug. 15, to discuss the status of the agency's Kepler Space Telescope.
Recent images taken by FLAMINGOS-2 during its last commissioning phase dramatically illustrate that the instrument was worth the wait for astronomers around the world who are anxious to begin using it.
There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light.
Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it’s not too close to Earth and her Moon, and it's not too far. In fact, it's just right.
An international team of scientists has devised a method for measuring the internal properties of a star that offers more accurate assessments of the star's orbiting planets.
Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time.
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...
