IAU Speaks Out Against Planet Naming Site Uwingu
2013-04-15 12:01:28

Lee Rannals for redOrbit.com — Your Universe Online A few months ago, a new space website opened up its doors for the public to start selecting the names of other planets. Now, the International Astronomical Union (IAU) has stepped up and pointed out this isn't exactly the protocol for the scientific process of naming cosmic bodies. Over 800 planets have been detected outside the Solar System so far, and thousands more are still waiting to be confirmed. Recently, the website...

2013 Carl Sagan Fellowships Selected By NASA
2013-04-10 05:06:08

NASA's Jet Propulsion Laboratory NASA has selected five planet hunters to receive the 2013 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars. The primary goal of the fellowship program is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's...

Project 1640 Imaging System Allows Astronomers To See Distant Exoplanets
2013-03-13 21:39:14

Brett Smith for redOrbit.com — Your Universe Online Using a state-of-the-art telescopic imaging system, astronomers are now able to see planets that orbit distant stars, known as exoplanets, more easily and in greater detail, according to a report in the Astrophysical Journal. Scientists gather information from distant planets via the light they radiate, referred to as their spectra, and previously, astronomers have only been able to analyze planets as they pass in front of, or...

Astronomers Make First Direct Observation Of A Forming Planet
2013-02-28 11:00:58

[WATCH VIDEO: Flying Through The HD 100546 System] Lee Rannals for redOrbit.com — Your Universe Online Astronomers, for the first time, may have made a direct observation of a planet forming inside a thick disc of gas and dust. An international team led by Sascha Quanz, of the Swiss Federal Institute of Technology (ETH Zurich), used the European Space Observatory's (ESO) Very Large Telescope (VLT). Their discovery could help improve scientists' knowledge of how planets form and...

Uwingu Website Invites Public To Help Name Distant Planets
2013-02-27 19:18:19

Alan McStravick for redOrbit.com — Your Universe Online Have you ever looked out into the heavens and a perfect name for an as-yet-unnamed planet just popped into your head? Until today, chances are, unless you were close personal friends or family of an astronomy professional, that name would sit idly in your own mind. Thanks in no small part to a team of leading astronomers, planetary scientists, former space program executives and educators; a new space website called Uwingu...

White Dwarfs May Host Habitable Exoplanets
2013-02-25 12:28:16

Lee Rannals for redOrbit.com - Your Universe Online Scientists are on the hunt to find habitable exoplanets, and a new discovery might mean there are even more candidates out there than previously thought. A new theoretical study suggests even dying stars might be able to have orbiting exoplanets that are hospitable to extraterrestrial life. As a star dies, its outer layers puff off, leaving behind a hot core known as a white dwarf which is typically about the size of...

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...

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...
