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...

More Than 1,000 Exoplanets Have Been Discovered Since 1992
2013-10-25 14:17:10

Lee Rannals for redOrbit.com - Your Universe Online The search for extra-terrestrial planets has been ongoing for at least the past 21 years. Since the early days of exoplanet hunting, the number of such planets identified by scientists has pushed beyond a thousand, thanks largely to the advent of high-tech space observatories, such as the Kepler Space Telescope. Exoplanets, or alien planets, are those planets that exist outside of our Solar System. So far, scientists have discovered...

President Barack Obama Thanks NASA Employees And Public Servants

NASA President Obama met with two NASA employees and 32 fellow public servants in the East Room at the White House in Washington to express gratitude and acknowledge their selection as recipients and finalists of the prestigious 2013 Samuel J. Heyman Service of America Medals or Sammies. The medals are presented annually by the nonprofit, nonpartisan Partnership for Public Service to recognize the outstanding achievements of federal workers and their significant work for our nation....

Planetary Building Blocks Found Around White Dwarf Star

[ Watch the Video: Oxygen And Water Evidence From Extrasolar Asteroid? ] redOrbit Staff & Wire Reports - Your Universe Online For the first time, researchers have discovered two essential components required for habitable planets – water and a rocky surface – existing together outside of our solar system. Researchers from the University of Cambridge, the University of Warwick and the University of Kiel report in the latest edition of the journal Science that they had analyzed...

Sunless Planet Found Wandering In Galaxy
2013-10-10 10:04:16

Brett Smith for redOrbit.com - Your Universe Online While most of the planets seen outside our solar system have been observed orbiting a distant star, one of the most recently discovered exoplanets found was seen wandering the depths of space without the warming comfort of a nearby sun. The newly discovered planet PSO J318.5-22 is 80 light-years from Earth and has a mass about six times that of Jupiter. According to a study in Astrophysical Journal Letters that described the discovery,...

Fomalhaut Triple Star System
2013-10-04 09:17:50

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for exoplanets – worlds outside of our own solar system – has grown exponentially in the last decade or two. And while news about the hunt for planets that could potentially support life dominates the headlines, it is equally important to understand the star systems that host these distant space rocks. One system that has garnered significant attention is the nearby star system known as Fomalhaut, partially...

The Hunt For Extraterrestrial Life On Cloudy Extra-Solar Planets
2013-09-26 11:05:19

Brett Smith for redOrbit.com - Your Universe Online An international research team has created a map of the clouds that ensconce Kepler 7b, a distant planet outside our solar system, according to reports published by The Astrophysical Journal and Astrophysical Journal Letters. The studies’ researchers said their findings are a step forward in determining which planets outside our Solar System, also known as exoplanets, can host extraterrestrial life. Kepler 7b orbits a Sun-like...

Spitzer Hunting For Exoplanets
2013-09-25 10:38:33

Brett Smith for redOrbit.com - Your Universe Online After 10 years of orbiting the sun, the Spitzer Space Telescope is now playing a completely different role than it was a decade ago – hunting for exoplanets outside the solar system. "When Spitzer launched back in 2003, the idea that we would use it to study exoplanets was so crazy that no one considered it," said Sean Carey of NASA's Spitzer Science Center  in a statement. "But now the exoplanet science work has become a...

Scientists May Soon Have New Tools To Answer The 'Are We Alone' Question
2013-09-12 15:23:08

Lee Rannals for redOrbit.com - Your Universe Online Scientists are working on new tools to help detect whether or not life exists on planets far away from our Solar System. Life on Earth is able to send off signals into the atmosphere, such as microbes emitting methane and nitrous oxide. When these chemicals are present in sufficient quantities they become indicators of life and are known as atmospheric biomarkers. Detecting them in the atmosphere of exoplanets could indicate whether or...

Exoplanet With Water-Rich Atmosphere
2013-09-06 07:43:41

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for a habitable planet beyond Earth is on. Scientists have been searching the heavens to find an exoplanet that is just the right distance from its host star to support liquid water, all the while targeting a surface gravity we would be familiar with and an atmosphere oozing with oxygen. Such a planet has not yet been found, but progress has been made, and we continue to find smaller and smaller planets closer to the...

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

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...
