Gas giant Jupiter
2014-03-12 05:09:27

April Flowers for redOrbit.com - Your Universe Online An international team of researchers recently got a sneak peek deep into the lower atmospheric layers of gas giant planets such as Jupiter or Saturn using Deutsches Elektronen-Synchrotron's (DESY) X-ray laser FLASH. The team's observations, led by Dr. Ulf Zastrau of the University of Jena, demonstrate how liquid hydrogen becomes a plasma. The findings, published in Physical Review Letters, also provide information on the material's...

Exoplanet Search Techniques Needs To Be Refined
2014-02-20 04:11:01

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

Planets of Peril has signed a deal to become a feature film! LONG BEACH, Calif., Dec. 30, 2013 /PRNewswire/ -- Planets in Peril has signed a deal to become a feature film. The details of the deal are not yet available to the public, but preproduction has begun. Here's a little bit about Planets in Peril from the creator, Douglas Vermeeren: The idea for Planets in Peril came while attending my film classes in the early 1990 s. Although I believe I've been working on the concept and...

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...

Astronomers Discover Seventh Planet Orbiting Nearby Star System
2013-10-25 15:26:17

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a seventh planet orbiting a dwarf star, known as KIC 11442793, making it the first Kepler planetary system with this many alien worlds. The star is about 2,500 light years from Earth and its planetary system could be a record holder. All seven planets in the system orbit much closer to their host star, meaning the system is very crowded when compared to even our own Solar System. Scientists say that the...

Methane Secrets Hold Key To Understanding Planetary Interiors
2013-09-12 14:28:33

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature Communications, say their study on methane's secrets will help scientists better understand the chemistry of planetary interiors. Hydrocarbon methane (CH4) is one of the most abundant molecules in the universe, but its behavior under the conditions found in planetary interiors is poorly understand due to contradictory information from various modeling studies. Studying various...

Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope
2013-08-06 05:23:10

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light. Based on the length of the transit, the amount of light that is blocked, and other factors, astronomers can infer a lot of information about the planet. Additionally, researchers will find planets by...

Complex Origins Of Solar Systems
2013-07-25 11:12:46

John P. Millis, PhD for redOrbit.com - Your Universe Online Centuries ago, as astronomers began to discover the extent of our solar system, they also began to develop theories on how our Solar System was formed and how it evolved. The challenge was that the only model available was that of our own - other planetary systems would not be discovered until the later part of the 20th century - so researchers assumed that all solar systems would likely look like ours: central star, small rocky...

Blue Exoplanet Shares Earth Color Only
2013-07-11 09:39:25

Brett Smith for redOrbit.com - Your Universe Online Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth. The international team that made the discovery noted similarities between these two planets likely end at their color, as the exoplanet HD 189733b is being described as a gas giant with thousand degree temperatures and violent winds in its...

Wind And Clouds Play An Important Role In Hot Jupiter Atmospheres
2013-07-05 05:27:23

Lee Rannals for redOrbit.com - Your Universe Online Astronomers studying eight exoplanets falling into the "hot-Jupiter" class suggest winds and clouds play an important role in the atmospheric make up of these exotic planets. Hot-Jupiters are giant planets similar in size to Jupiter, but orbiting very close to their stars. Astronomers are able to detect which gases are present in their atmosphere by analyzing the spectrum of starlight filtered through the planet's atmosphere when it...

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...

Solar System
2012-10-22 06:09:41

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...
