NASA is the United States government agency responsible for the civilian space program as well as aeronautics and aerospace research. It has conducted many spaceflight programs throughout its history, including launching the first American satellites and unmanned probes to explore planets like Venus and Mars. Recently, NASA discovered Kepler-452b, a planet similar to Earth located 1,400 light years away that is orbiting in the habitable zone of its star, making it a potential candidate for harboring life.

The National Aeronautics and Space Administration (NASA) is the United States
government agency responsible for the civilian space program as well as aeronautics
and aerospace research.
NASA has conducted many programs spaceflight and unmanned the its history. The
program launched the first American manned satellites in Earth orbit for scientific
purposes and communications, and scientific probes sent to explore planets in the
solar system, starting with Venus and Mars, and including "Grand Tours" of the outer
planets.

2. The NASA found a new planet similar to Earth, located 1,400 light years away
dimensions. This is Kepler-452b and call it "the older cousin" of our planet. It is
located in a "habitable zone".
The Kepler mission, responsible for the discovery, is a space program that is
dedicated to finding planets similar to Earth in the Milky Way. As they explained,
orbiting in a "habitable zone" around a star similar to the sun.
