John P. Millis, Ph.D. for redOrbit.com - Your Universe Online 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 – are of equal importance in the search for a Sun-like star. Such a glowing orb would need to have a similar mass, temperature, and spectral type. These parameters are somewhat easy to measure, but...

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

Gerard LeBlond for redOrbit.com - Your Universe Online Friction generates heat and NASA scientists have developed a computer model that shows how friction may help distant Earth-sized planets survive dangerous orbits. Other star systems commonly house Earth-sized planets. To some, friction heat could be destructive, but given the correct amount of heat, it could be helpful in creating conditions to support life. “We found some unexpected good news for planets in vulnerable orbits....

Worldwide Contest To Name Exoplanets And Their Host Stars

International Astronomical Union 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. The proposed names will be submitted by astronomy clubs and non-profit organizations interested in astronomy, and votes will be cast by the public from across the world through the web platform...

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

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

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...

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...

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...
