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...

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...

Hunting For Exoplanets
2013-07-19 10:34:45

redOrbit Staff & Wire Reports - Your Universe Online The hunt is on for planets that, like Earth, have the conditions necessary for life to survive on their surfaces. But what exactly are scientists looking for? Earlier this week, NASA officials shed a little light on precisely what conditions they are seeking on worlds located beyond our solar system. These worlds, which are also known as exoplanets, have to meet a handful of different criteria in order to be considered potentially...

What Really Makes A Habitable Planet?
2013-05-04 05:41:48

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The Holy Grail in the search for planets outside our solar system is finding one that could potentially support life. Traditionally, this means finding a planet with features similar to Earth, which is just the right distance from its host star that liquid water could be supported on the surface. Scientists believe the presence of liquid water on the surface is a necessary component for the proliferation of life. And a...

White Dwarf Search May Yield Habitable Planets
2013-04-25 05:25:40

April Flowers for redOrbit.com - Your Universe Online A dead star, known as a white dwarf, will eventually cool down and fade away because it has no energy source. A new study led by Professor Dan Maoz of Tel Aviv University's School of Physics and Astronomy suggests that white dwarfs can still support habitable planets. The team, which includes Prof. Avi Loeb, Director of Harvard University's Institute for Theory and Computation and a Sackler Professor by Special Appointment at TAU,...

Earth-like Planets Could Be More Common Than Previously Believed
2013-03-13 04:45:39

April Flowers for redOrbit.com - Your Universe Online A new study from Penn State's Department of Geosciences suggests that the number of potentially habitable planets is greater than previously thought, and that some of those planets are likely to be found around nearby stars. "We now estimate that if we were to look at 10 of the nearest small stars we would find about four potentially habitable planets, give or take," said Ravi Kopparapu, a post-doctoral researcher in geosciences....

Goldilocks Zone Serves Up Another Super Earth
2012-11-09 05:00:30

[ Watch the Video: New Habitable Zone Super-Earth Found in ExoSolar System ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Mankind´s fascination with the possibility of life on other worlds has been a mainstay of science fiction for more than a century. But it wasn´t until the last decade that we possessed the technology to begin searching in earnest for habitable planets outside of our solar system. While the tally of new worlds has seen a surge...

Strange Exoplanet Environments May Be Suitable For Extreme Lifeforms
2012-09-12 12:42:21

April Flowers for redOrbit.com - Your Universe Online In the hunt for the elusive "blue dot" exoplanet — a planet with roughly the same characteristics as Earth — astronomers have discovered a veritable rogue's gallery of oddballs. From scorching hot worlds with molten surfaces to frigid ice balls, the planets outside our solar system are vastly different. New research, published in the Astrobiology journal, reveals that life might actually be able to survive on some of the...

Habitable Zone Planets Could Be Numerous
2012-09-11 12:14:34

Lee Rannals for redOrbit.com - Your Universe Online Researchers predict that there may be even more planets capable of hosting life out there than previously thought. Scientists presenting at the British Science Festival in Aberdeen said that new computer models may show there are far more planets that lie in the "habitable zone" than previously estimated. A new model allows scientists to identify planets that contain underground water which is still in the state of a liquid through...

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...
