The holy grail of planetary astronomy is to find a solar system that mirrors our own. While a lot of effort has been placed on finding a planet with Earth-like properties – the right size, an atmosphere, the right temperature – of equal importance is the search for a Sun-like star.

Distant Earths May Need Balanced Friction Tides To Support Life
2014-07-10 12:52:42

Friction generates heat and NASA scientists have developed a computer model that shows that friction may help distant Earth-sized planets survive dangerous orbits.

Worldwide Contest To Name Exoplanets And Their Host Stars
2014-07-09 03:48:54

For the first time, in response to the public’s increased interest in being part of discoveries in astronomy, the International Astronomical Union (IAU) is organizing a worldwide contest to give popular names to selected exoplanets along with their host stars.

Using A Stellar Ultrasound To Determine Ages Of Young Stars
2014-07-04 11:40:33

The age of ‘baby stars’ is difficult to gauge, but a newly published study in the journal Science has revealed scientists used a technique similar ultrasound technology to determine how old these young stars are.

Planetary System Gliese 581
2014-07-04 06:31:29

Gliese 581g, described as one of the most Earth-like planets when it was originally discovered four years ago, probably does not exist, researchers from Penn State University and the University of Texas at Austin report in the latest edition of the journal Science.

newly discovered planet in binary system
2014-07-04 04:31:19

Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science.

Potentially Habitable Exoplanet With Earth-Like Temperatures Found
2014-06-27 08:24:53

Astronomers have discovered a new, potentially habitable Super-Earth believed to possess temperatures comparable to those found here, but with much larger seasonal shifts, provided the atmosphere is similar to our planet.

SPHERE first light
2014-06-04 08:00:35

SPHERE — the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument — has been installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile and has achieved first light.

Two Ancient Worlds Discovered In Neighboring Galactic Cluster
2014-06-04 07:02:00

Using new data from the HARPS spectrometer at the ESO’s La Silla observatory in Chile, an international team of scientists have discovered two exoplanets orbiting a nearby ancient star.

Two Planets Will Be Eaten By Their Star
2014-06-02 03:21:55

Two worlds orbiting a distant star are about to become a snack of cosmic proportions. Astronomers announced on Monday that the planets Kepler-56b and Kepler-56c will be swallowed by their star in a short time by astronomical standards. Their ends will come in 130 million and 155 million years, respectively.

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
2004-10-19 04:45:41

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...
