Alien Planets And The Search For Intelligent Life
2013-02-08 13:36:28

[ Watch the Podcast: The Search For Alien Life With Guest Dr. Eric Mamajek (Part 3): Your Universe Today Podcast ] Lee Rannals for redOrbit.com - Your Universe Online A group of astronomers have determined through NASA Kepler mission data that less than one in a million stars in the Milky Way galaxy could have intelligent life. The University of California, Berkeley team used the Green Bank Telescope in West Virginia to look for intelligent radio signals from planets around 86 of...

[ Listen to the Podcast: “How Planets Form” With Guest Dr. Eric Mamajek (Part 1): Your Universe Today Podcasts ] Lee Rannals for redOrbit.com - Your Universe Online The Subaru Telescope has helped astronomers capture the first vivid infrared image of a distant planet forming from a young star. Astronomers wrote in Astrophysical Journal Letters about an image of a curved arm of dust extending over a hole on a disk, which is a feature that could provide evidence that...

Exoplanets In Our Own Back Yard?
2013-02-06 11:04:34

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Kepler space telescope have found that six percent of red dwarf stars have habitable, Earth-like planets. Red dwarfs are considered to be the most abundant stars in our galaxy, so it is feasible that one of these Earth-like planets could be just 13 light-years away, when taking into account the astronomers new research published in The Astrophysical Journal. The Harvard-Smithsonian Center for Astrophysics...

Super-Earths May Actually Be Mini-Neptunes
2013-02-04 19:14:15

Lee Rannals for redOrbit.com — Your Universe Online Finding planets outside of our own Solar System has become a bit of a hot topic in the scientific community, and the enthusiasm behind the discovery of "Earth-like" planets has been on the rise, but a new study suggests we may want to tone down our excitement a bit. A new study led by Dr. Helmut Lammer of the Space Research Institute (IWF) at the Austrian Academy of Sciences says that maybe these "Earth-like" planets may not be...

Millis, Ph.D. for redOrbit.com — Your Universe Online In this installment of our new podcast series Your Universe Today, redOrbit´s resident astronomer Dr. John Millis spoke with Dr. Eric Mamajek from the University of Rochester about the possibility of finding life beyond Earth. This is the final interview in a three-part series on the topic. If you haven´t already, be sure to listen to part 1 “How Planets Form” and part 2 “Planet Hunting.”...

Living On The Habitable Edge

[ Planet Hunting: Your Universe Today Podcasts ] April Flowers for redOrbit.com - Your Universe Online Astronomers searching for extraterrestrial life have begun to consider exomoons, or those likely orbiting planets outside our solar system, and new research has found that they are just as likely to support life as exoplanets. René Heller of Germany's Leibniz Institute for Astrophysics Potsdam and Rory Barnes of the University of Washington and the NASA Astrobiology...

Brown Dwarf Weather Map Shows A Stormy Atmosphere
2013-01-09 08:38:22

redOrbit Staff & Wire Reports - Your Universe Online By using the Hubble and Spitzer space telescopes, NASA officials say they have managed to complete the most detailed weather map to date for the cool, planet-like stars known as brown dwarfs. Brown dwarfs, which are also sometimes known as failed stars, form out of condensing gas but do not have the mass in order to fuse hydrogen atoms and produce energy, officials from the US space agency explained in a recent statement. As a...

Planets Galore Found By Kepler
2013-01-08 11:28:45

Brett Smith for redOrbit.com - Your Universe Online After completing a new analysis of data from the Kepler space observatory, NASA scientists announced that they have identified 461 new planet candidates – including four that closely mirror the size and distance from their sun as Earth. Kepler´s mission to find Earth-like planets was recently extended to 2016 after difficulties arose in processing the large volume of data produced by the orbiting observatory. Since the most...

Exocomets Are As Common As Exoplanets
2013-01-08 06:41:37

April Flowers for redOrbit.com - Your Universe Online A beautiful byproduct of our solar system's formation, comets trailing wispy tails across the night sky are icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble. Six likely comets around distant stars were recently discovered by astronomers at the University of California, Berkeley and Clarion University suggesting that comets — dubbed "exocomets" — are just as common in other stellar...

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...
