From early civilizations until today man has sought to explore and discover what is beyond our world. From the ancient discovery of the
wandering stars to the thousands of potential new planets found this decade, mankind has sought to make many astronomical advances. However some of these ‘breakthroughs’ that occurred throughout history happened to be more phantom than fact. Learn more at: http://www.armaghplanet.com/blog/8-phantom-moons-and-planets.html

Next Big Future reports: “We could be in the business of studying the atmospheres of habitable worlds 10 years from now,” says David Charbonneau, also of the Harvard-Smithsonian Centre for Astrophysics. If NASA launches the missions the space telescopes and we get lucky with analysis of Kepler data to confirm exoplanets, then we could be studying the atmospheres by 2017 or 2020 with new space based and new large ground based telescopes.
