Explanation:

• NASA’s Kepler mission observed a dip in the host star’s light, suggesting that the planet was crossing in front of the star during its orbit.
• To confirm, researchers turned to an instrument called Habitable-zone Planet Finder (HPF).
• At 100 light years from Earth, a low-mass star was sending signals in a pattern that suggested that an exoplanet was orbiting the star.
• It has confirmed that there is indeed an exoplanet.
• The scientific objective of the Kepler Mission is to explore the structure and diversity of planetary systems.
• It is an unmanned space observatory dedicated to find planets outside solar system with a particular focus on finding planets that might resemble Earth.
• The observatory was in commission for just under 9 years, from its launch in March 2009 to its decommission on Nov. 15, 2018.
