Latest Planet Stories
Finding the next earth just got one step easier. A new NASA instrument designed to study dust in the so-called habitable zone around a star may help future missions centered around capturing images of planets similar to Earth.
Scientists use laser-driving compression experiments (cool) to recreate the planetary formation process (even cooler).
New images of Ceres captured by NASA’s Dawn spacecraft during its approach to the dwarf planet are the best yet obtained by the spacecraft, and appear to show evidence of craters as well as a mysterious white spot first discovered by the Hubble Space Telescope in 2003.
While some astronomers are looking for the existence of planets light years away from Earth, a team of Spanish researchers has suggested there could be at least two planets that have yet to be discovered in our very own Solar System.
Scientists have paired NASA's Cassini spacecraft with the National Science Foundation's Very Long Baseline Array (VLBA) radio-telescope system to pinpoint the position of Saturn and its family of moons to within about 2 miles (4 kilometers).
JACKSON HOLE, Wyo., Jan. 7, 2015 /PRNewswire/ -- Travel media company Lonely Planet announces the acquisition of a strategic stake in media house Teton Gravity Research (TGR).
On Tuesday, researchers working with data from NASA's Kepler space telescope announced the discovery of eight new ‘exoplanets’ located in the Goldilocks zone at the annual meeting of the American Astronomical Society.
The discovery was made when astronomers and engineers devised an ingenious way to repurpose Kepler for the K2 mission and continue its search of the cosmos for other worlds.
Even a shallow ocean, about 50 meters deep, would be enough to keep such a planet at relatively comfortable temperatures, averaging around 60 degrees Fahrenheit year-round.

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...
Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...
Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...
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...
