An international team of scientists has found 20 more exoplanets that might be suitable for human life and are similarto Earth in size.

The discovery, which came with the help of the Kepler space telescope, located 20 exoplanets that take anywhere from 18 to 395 Earth days , according to New Scientist. One such planet, known as KOI-7923.01, is slightly smaller than Earth and appears to be warm enough – though cooler than our home planet – to sustain life, the report added.

"If you had to choose one to send a spacecraft to, it's not a bad option," Jeff Coughlin, the leader of a Kepler team that identified the exoplanets, told New Scientist.

Kepler was in working order from 2009 until 2013, when it broke, and during that time, it collected data , according to Quartz. While the telescopewas only operational for a relativelyshort time, scientists are still pouring over all the imagery and making new discoveries such as this one.

Finding these 20 exoplanets was a long process. According to Phys.org, the scientists and eventually narrowed the list down to some 4,000 exoplanets with orbits of anywhere from a quarter of a day to 632 days. From there, they analyzed each of the exoplanets and found 20 that suit all criteria for Earth-like planets, the report added.

The exoplanets must go through another round of confirmation, however, because Kepler's issues arose while it was photographing that portion of the sky, Phys.org also said. The scientists remain confident that these are planets, and that they qualify to be listed as possibly habitable, but more observations will be necessary for a final confirmation, the report added.

"I believe that this is a much-improved catalog, so I'm eager to explore it further," Abel Mendez, director of the Planetary Habitability Lab at Arecibo Observatory, told New Scientist.

For years, NASA has updated as more are discovered; we'll find out soon if any of the new 20 make the list.
