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...

WASHINGTON, Jan. 7, 2013 /PRNewswire-USNewswire/ -- NASA's Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun's "habitable zone," the region in the planetary system where liquid water might exist on the surface of a planet.

Citizen Astronomers Discover 15 New Planet Candidates In The Habitable Zone
2013-01-07 13:44:01

redOrbit Staff & Wire Reports - Your Universe Online Volunteers affiliated with an Oxford University citizen astronomy project have discovered more than a dozen new potential planets orbiting in the habitable zones of other stars, officials from the UK-based educational institution announced on Monday. "Volunteers from the Planethunters.org website, part of the Oxford-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars,"...

Binary Star Orbit Shifts Could Force Planetary Ejections
2013-01-07 03:28:35

redOrbit Staff & Wire Reports - Your Universe Online The orbits of distant binary stars can become altered over time, potentially causing violent disruptions in their planetary systems and possibly causing worlds to become scattered or ejected, an international team of astrophysicists has discovered in a new study. According to the researchers, all planetary systems in which one star is orbited by a second, companion star, can be altered by the gravity of the companion star, but...

Our Galaxy Abounds With Planets Says New Study
2013-01-03 14:45:20

Lee Rannals for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. Astronomers from California Institute of Technology (Caltech) wrote in the Astrophysical Journal that our galaxy may be filled with more planets than researchers had previously thought — a discovery that could have deep implications for our understanding of the universe....

Astronomers Believe 2013 Will Be Record Year For Habitable Planet Discoveries
2012-12-31 13:44:58

Lee Rannals for redOrbit.com — Your Universe Online While 2012, like most years, held some significant findings, 2013 could be one for the record books when it comes to looking for habitable planets. Astronomers know that they are on the verge of discovering the first truly Earth-like extrasolar planet (exoplanet) in 2013. There have been a few exoplanets in the last few years that are similar in size, inferred surface temperature, and distance to their parent star, but scientists...

How Planets Form: Your Universe Today Podcasts
2012-12-31 09:56:42

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Starting in early 2013, redOrbit will be launching a new podcast series called Your Universe Today, where we interview leading scientists about cutting-edge research in everything from space travel to the origins of our Universe. But we´re in the holiday spirit and couldn´t wait until January to unveil our new podcast project, so we´ve decided to give you a sneak peak of what´s to come. In...

Combining Planetary Science And Astronomy To Hunt For Exoplanets
2012-11-29 08:41:26

Lawrence LeBlond for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. Have you ever looked up at the night sky and wondered just how many of the stars you see might have planets orbiting them, and if so, what those planets might be like? Our galaxy alone contains at least 200 billion stars, and researchers have been searching effortlessly to...

The Path To Planet Formation
2012-11-28 11:36:08

April Flowers for redOrbit.com - Your Universe Online A new study, using the capabilities of the Subaru Telescope, has captured a clear image of the protoplanetary disk of the star UX Tau A. An international team of researchers from the National Astronomical Observatory of Japan (NAOJ) and the Japanese universities of Kobe, Hyogo, and Saitama released a detailed study of the disk's characteristics, suggesting that its dust particles are large in size and non-spherical in shape. The...

Astronomers Find Super Jupiter Planet
2012-11-19 11:25:04

Lee Rannals for redOrbit.com - Your Universe Online A rare glimpse of a "Super Jupiter" has been caught while the planet was circling around its host star with a mass 2.5 times that of our Sun. Astronomers, led by Joseph Carson (College of Charleston and Max Planck Institute for Astronomy) and using the Subaru Telescope, were able to capture an image of the planet around the massive star K Andromedae. Only a few exoplanets have ever been captured in actual astronomical images,...

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...
