Answer 1

makes Earth unique among the thousands of other planets we've discovered. Since the fall of 1997, NASA satellites have continuously and globally observed all plant life at the surface of the land and ocean. During the week of Nov. 13-17, NASA is sharing stories and videos about how this view of life from space is furthering knowledge of our home planet and the search for life on other worlds.

As a young scientist, Tony del Genio of NASA's Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.

"I thought, 'Wow, this is a one-time opportunity,'" del Genio said. "I'll never meet anyone else who found a planet."

That prediction was spectacularly wrong. In 1992, two scientists discovered the first planet around another star, or exoplanet, and since then more people have found planets than throughout all of Earth's preceding history. As of this month, scientists have confirmed more than 3,500 exoplanets in more than 2,700 star systems. Del Genio has met many of these new planet finders.

Answer 2

it cannot be proved that there is life on other planets . But Saturn's moon i.e Titan and Jupiter's moon i.e Europa can have aliens supportive life. titan which is Saturn's moon has methane present in the form of liquid water . thus it can support life too. about a year or two NASA discovered a planet from Kepler telescope which had the same temperature as earth and also ice caps in the poles . thus this can also support life .
people present on those planets are not likely to be like us . their habitats may be different . their respiration process may be different . aliens present on those planets may be more advanced than us .
