New Evidence Suggests Mercury Was Formed From A Stellar Collision
2014-07-08 10:50:50

Gerard LeBlond for redOrbit.com - Your Universe Online Planet Mercury has an unusual metal-rich composition which has baffled the scientific community. However, new evidence may have solved this mystery. According to a new study published online in Nature Geoscience on July 6, Mercury along with other space objects in the solar system with an unusual metal-rich composition, may be left over from stellar hit-and-run collisions in the early formation of the solar system. The...

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

redOrbit Staff & Wire Reports - Your Universe Online 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. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

Astronomers Use AKARI Orbiting Observatory To Map Space’s Icy Wastes
2014-06-26 03:40:16

Royal Astronomical Society Using the AKARI orbiting observatory, astronomers from the Open University have made the first large-scale maps of icy material where stars are forming. In a challenge to conventional ideas about the formation of water in space, they find ice in regions with little dust or gas. Dr Helen Fraser, who led the new work, presented the results in her talk at the National Astronomy Meeting in Portsmouth this week. Launched by the Japanese space agency JAXA in 2006,...

Using A Telescope To Dig For Ice On Pluto
2014-06-26 03:59:09

Royal Astronomical Society In just over a year, the New Horizons spacecraft will fly past Pluto, giving us our first detailed look at the dwarf planet. Anticipating this encounter, St Andrews undergraduate student Ailsa Whitelaw and her supervisor Dr Jane Greaves have used forgotten data to map the sub-surface of Pluto, peering beneath its icy coating to uncover hidden chemicals that give a hint of the future of this distant world. Dr Greaves will present the new work in her talk on...

Brett Smith for redOrbit.com - Your Universe Online A joint research effort between NASA and the European Space Agency has found proof that nitrogen within the atmosphere of Saturn's moon Titan came from conditions very similar to those that formed most of the ancient comets in the Oort cloud, according to a new report in the Astrophysical Journal Letters. The Oort cloud is a spherical cloud of predominantly icy space rocks believed to surround the Sun at a radius far outside the Solar...

redOrbit Staff & Wire Reports - Your Universe Online Researchers from University College London and the University of New South Wales have reportedly developed a new, more powerful and more accurate way to detect extraterrestrial life that focuses on methane. Writing in the latest edition of the journal Proceedings of the National Academy of Sciences (PNAS), the study authors explain their development of a new spectrum for hot methane capable of detecting the molecule at...

The Longfellow Clubs takes innovative steps to decrease energy, water, and gas usage. Natick, MA (PRWEB) June 10, 2014 In the past decade, The Longfellow Clubs, a group of sports clubs and children’s centers based in the greater Boston area, has become a national leader in the fitness industry, showing resource-intensive businesses that even a fitness center can get into environmental shape. Since 2006, The Longfellow Clubs has pioneered several practices new to the industry that prove...

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

Harvard-Smithsonian Center for Astrophysics 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. "As far as we know, this is the first time two known exoplanets in a single system have a predicted 'time of death,'" says lead author...

Exoplanets Come In Three "Neapolitan" Flavors
2014-06-02 03:09:48

Harvard-Smithsonian Center for Astrophysics The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream. We have small, rocky terrestrials like Earth and Mars, and large gas giants like Neptune and Jupiter. We're missing the astronomical equivalent of strawberry ice cream - planets between about one and four times the size of Earth. NASA's Kepler mission has discovered that these types of planets are very common around other stars. New research...

Astronomers Discover The "Mega-Earth"
2014-06-02 03:30:17

Harvard-Smithsonian Center for Astrophysics Astronomers announced on Monday that they have discovered a new type of planet - a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldn't form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas giant. This planet, though, is all solids and much bigger than previously discovered "super-Earths," making it a "mega-Earth." "We were very surprised when we realized what we had...

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...

Planetary and Space Science

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...
