Astronomers Puzzled By Discovery Of Giant Planet Orbiting Distant Star
2013-12-05 12:56:55

[ Watch the Video: What Planet Has Astronomers Puzzled? ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found the most distant orbiting planet to date, and the puzzling discovery is effectively throwing a wrench in planet formation theories. Scientists reported in The Astrophysical Journal Letters that exoplanet HD 106906 b is orbiting its star at 650 times the average Earth-Sun distance. "This system is especially fascinating because no model of either...

How Many Habitable Exoplanets Exist
2013-11-26 13:17:30

John P. Millis, PhD for redOrbit.com - Your Universe Online In the last decade, exoplanet scientists have been finding new worlds at a brisk pace. But as the number of planetary bodies in our galaxy rises, questions about how many of these may, in fact, be habitable have been reaching a crescendo. The debate centers on the criteria for what it takes for a planet to be considered habitable. It seems the presence of liquid water on the surface is necessary, though some researchers are now...

Sunny Outlook For NASA Kepler's Second Light
2013-11-26 12:09:10

NASA You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae. In May, the Kepler spacecraft lost the second of four gyroscope-like reaction wheels, which are used to precisely point the...

In The Hunt For Habitable Planets, A New Model May Be Key
2013-11-14 13:54:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers using new theoretical models have created a new method to simplify the search for Earth-like planets. The new models help rule out the possibility of Earth-like conditions on certain planets outside of our solar system. Yann Alibert, of the Center for Space and Habitability (CSH) at the University of Bern, and colleagues based the study on the mass and radius of a planet, helping to determine criteria that exclude the...

Alien Worlds: How Common Are Habitable Planets?
2013-11-05 02:51:36

[ Watch the Video: Earth May Not Be So Unique After All ] redOrbit Staff & Wire Reports - Your Universe Online New statistical analysis of data obtained by NASA’s now-retired Kepler spacecraft has revealed that one out of every five sun-like stars have at least one Earth-sized planet in the habitable zone. “What this means is, when you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only...

Young women will partner with mentors, engage in hands-on activities and discover they have the right stuff to become STEM professionals. Chicago, IL (PRWEB) November 04, 2013 On Saturday, November 9, the Adler Planetarium will host the first-ever Girls Do Hack, a one-day event dedicated to inspiring young women to pursue careers in science, technology, engineering and mathematics (STEM). Girls Do Hack will immerse 48 young women, ages 14 to 18, from Chicago Public Schools in activities...

Scientists Meet To Discuss 833 New Exoplanets
2013-11-04 16:21:02

Lee Rannals for redOrbit.com - Your Universe Online An international group of scientists are gathering for the second Kepler Science Conference this week at NASA’s Ames Research Center in Moffett Field, California. Researchers will be discussing the latest findings from the Kepler Space Telescope data, which includes the discovery of 833 new candidate planets. Ten of the new exoplanets are less than twice the size of Earth and orbit in the habitable zone. New Kepler data shows that...

Explanet Same Size As Earth
2013-10-30 16:15:10

Brett Smith for redOrbit.com - Your Universe Online In August, an international team of researchers announced the discovery of a planet outside our solar system - also referred to as an exoplanet - that orbits its star in just 8.5 hours and is roughly the same size as Earth. Now, the same research team members that found the planet, dubbed Kepler 78b, have made another startling discovery: the planet’s mass is roughly the same as our own. "This planet is a complete mystery," said...

Exoplanets With Too Much Carbon Are Most Likely Waterless
2013-10-26 04:14:31

redOrbit Staff & Wire Reports - Your Universe Online Diamond planets and other worlds that are rich in carbon might be waterless, NASA researchers explained earlier this month at the 45th meeting of the American Astronomical Society Division of Planetary Sciences in Denver. Torrence Johnson, a Senior Research Scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, and his colleagues explain that since our sun is a carbon-poor star, the Earth is a planet that is...

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
2012-05-28 10:21:45

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...

Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
