Latest Exoplanetology Stories
There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year.
High-altitude balloons have long been used by scientists who study the Earth, the sun and the stars to gain a better view of their targets by carrying their telescopes far into the stratosphere.
NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March.
NASA’s Kepler space telescope has located a new planet that wobbles wildly on its axis much like a spinning toy top, with its tilt varying by as much as 30 degrees over an 11 year span.
Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope.
Tatooine, a fictional planet with two stars that is best known as the home of Luke Skywalker in the Star Wars movie franchise, may not be as farfetched as one might think.
A new paper argues that some planetary bodies may hold 'superhabitable' environments even more suitable for life than those found here on Earth.
An international group of astronomers has discovered a new, roughly Neptune-sized exoplanet orbiting the brightest star in a binary system more than 400 light years from Earth, according to a study appearing in the most recent edition of The Astrophysical Journal.
There have been more than one thousand planets confirmed outside our solar system, but only a few are within star clusters. Using the European Southern Observatory’s (ESO) HARPS instrument, researchers have found three new planets in the star cluster Messier 67.
A team of astronomers has discovered a new giant planet that could have twice the mass of Jupiter.
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...
