An international group of scientists has successfully discovered 20 or more exoplanets that are located in the Goldilocks zone and have the potential to support life. The research team, led by Susan Thomson of the SETI Institute, analyzed information collected from the Kepler Space Telescope and found out that there might be 20 more exoplanets in the cosmos that might sustain human life.

Out of the 4,034 exoplanets listed by the scientists, 20 most suitable planets were finally selected that have the possibility sustain life. Among them, one of the most promising worlds is KOI-7923. It is almost the size of the Earth and has a year comprising of 395 days. IT is a bit colder than Earth but not so cold that it cannot support life.

The co-author of the study, Jeff Coughlin of the NASA Ames Research Center said that if there is need to send spacecraft to one of those 20 planets, then it would definitely be the KOI-7923. But he also stressed on the fact that more in-depth observations are needed to make final confirmation about these potentially habitable planets. Kepler Space Telescope only managed to observe the transits once or twice and provided the data accordingly. Coughlin told the New Scientist that he and his team are 70-80% sure about the presence of these habitable exoplanets, but for final confirmation, they need strong observations made by the Hubble space telescope or ground-based observatories.

Kepler Space Telescope was launched in back 2009 with the mission of finding exoplanets in space. It broke down in 2013 but till then it managed to cover almost 150,000 stars, and till now scientists have discovered thousands of exoplanets by analyzing its data.
