WASHINGTON, Dec. 16, 2014 /PRNewswire-USNewswire/ -- NASA has selected SpaceX to provide launch services for the Transiting Exoplanet Survey Satellite (TESS) mission.
Among the billions and billions of stars in the sky, where should astronomers look for infant Earths where life might develop?
Planets orbiting close to low-mass stars — easily the most common stars in the universe — are prime targets in the search for extraterrestrial life.
Planet hunters received some good news recently. A new study concluded that, on average, sun-like stars aren't all that dusty. Less dust means better odds of snapping clear pictures of the stars' planets in the future.
An international group of astronomers is the first to measure the passing of a super-Earth exoplanet in front of a bright, nearby Sun-like star using a ground based telescope.
To find other planets, conventional wisdom would tell you to follow the stars. NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory, however, tell us to follow the dust.
NASA has officially confirmed the Transiting Exoplanet Survey Satellite (TESS) mission, clearing it to move forward into the development phase. This marks a significant step for the TESS mission, which would search the entire sky for planets outside our solar system, known as exoplanets.
Astronomers using NASA’s Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars.
A recently launched European satellite could reveal tens of thousands of new planets within the next few years, and provide scientists with a far better understanding of the number, variety and distribution of planets in our galaxy.
For their latest discovery, Yale astronomers and the Planet Hunter program have found a low-mass, low-density planet with a punctuality problem.

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...
