Latest Planetary habitability Stories
Swiss scientist Michel Mayor, who heads the European team that announced the discovery of a new potentially habitable planet, has his sights set on an even bigger target -- detecting signs of extraterrestrial life.
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. Green, yellow or even red-dominant plants may live on extra-solar planets, according to scientists.
A recent study found 20 new star systems in the sunâ€™s local neighborhood. Most of the new discoveries are red dwarfs, much smaller and dimmer than the sun. Yet scientists are growing more confident that these stars could host habitable planets.
More than one-third of the giant planet systems recently detected outside our solar system may harbor Earth-like planets covered in deep global oceans that offer abundant potential for life, according to a new study by scientists associated with NASA's Astrobiology Institute.
In the search for life on other worlds, scientists can listen for radio transmissions from stellar neighborhoods where intelligent civilizations might lurk or they can try to actually spot planets like our own in habitable zones around nearby stars.
By Maggie Fox, Health and Science Correspondent ST. LOUIS (Reuters) - Astronomers looking for extraterrestrial life now have a short list of places to point their telescopes.
Common wisdom among astronomers holds that most star systems in the Milky Way are multiple, consisting of two or more stars in orbit around each other. Common wisdom is wrong. This means planets may be more common than previously suspected.
Tiny zircon crystals dug up from ancient Australian deposits appear to have been formed right after the birth of the planet -- a finding that suggests that early on, Earth had a cool crust much like today's that could have harbored life, scientists said on Thursday.
A surprising new study by an international team of researchers has concluded Earth's continents most likely were in place soon after the planet was formed, overturning a long-held theory that the early planet was either moon-like or dominated by oceans.
More than half the stars in our galaxy are small, dim M dwarfs. Until recently, scientists believed these stars put out too little light to support life on any planets that orbited them. Now, that opinion has changed.

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...
