The recent discovery of the Earth-like planet Kepler-452b has overjoyed scientists worldwide, but our understanding of it will probably stop there, according to Tel Aviv University Professor Zvi Mazeh.
Mazeh, who was involved in the research conducted by NASA's powerful Kepler telescope, explains that the planet --located some 1,400 light years away -- is too far and too faint to learn anymore about it.
He stresses, however, that Kepler found many other planets that are, relatively speaking, much closer to Earth - some ten light years away. "They are near, and bright and therefore easier to study," he tells The Jerusalem Post.
He opines that the next big telescope sent into space will devote much of its time to studying these planets, and searching for biomarkers, to see if there is any evidence of life.
