"Although we know Earth has been habitable for most of its history, many questions remain regarding how these favorable conditions evolved with time, and the specific drivers behind those changes," Kane said. A common source is an exoplanet's host star's widely recognized, common or astronomical catalogue name. Name. The search for life in outer space is typically focused on what scientists call the "habitable zone," which is the area around a star in which an orbiting planet could have liquid water oceans—a condition for life as we know it. Moving forward, Kane plans to search for additional stars surrounded entirely by smaller planets. A team of astronomers was able to provide an estimate on the possible number of exoplanets that have Earth-like qualities within the Milky Way Galaxy. These stars will be prime targets for direct imaging with NASA telescopes like the one at Jet Propulsion Laboratory’s Habitable Exoplanet Observatory. ScienceDaily.

In 1992 astronomers reported the first planet-size masses around a dead star, the pulsar PSR1257+12, which sits 2,000 light-years away. Kane said: “This made me wonder about the maximum number of habitable planets it’s possible for a star to have, and why our star only has one. by Jules Bernstein, University of California - Riverside. A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter. Ein Exoplanet, auch extrasolarer Planet, ist ein planetarer Himmelskörper außerhalb (griechisch ἔξω) des vorherrschenden gravitativen Einflusses der Sonne, aber innerhalb des gravitativen Einflusses eines anderen Sterns oder Braunen Zwergs.

Exoplanets are planets, much like the ones orbiting in our Solar system, that we have discovered to be orbiting stars other than our Sun. Why then does our solar system only have one habitable planet if it is capable of supporting six? The result of all this is that any figure for the observed fraction of stars with exoplanets or the number of exoplanets per star is a lower limit. Paper. They are hidden by the bright glare of the stars they orbit. Number of known exoplanets by years. Projects like these offer more than new avenues in the search for life in outer space. R E = Earth radii. Because it doesn't have a Jupiter-like planet, it will be included as one of the stars checked for multiple habitable zone planets. Surprising Number of Exoplanets Could Host Life. The first exoplanets were found in the late 20th century (in 1989 , 1992 , or 1995 , depending on ones definition of an exoplanet), and since then we have discovered thousands of these worlds orbiting other stars in the galaxy. "By measuring the properties of exoplanets whose evolutionary pathways may be similar to our own, we gain a preview into the past and future of this planet—and what we must do to main its habitability.".
