Astronomers discover new exoplanet similar in size to Earth; planet Kepler-21b found using space and ground-based observations

The NASA Kepler Mission is designed to survey a portion of our region of the Milky Way Galaxy to discover Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist, and determine how many of the billions of stars in our galaxy have such planets. It now has another planet to add to its growing list. Researchers have shown that one of the brightest stars in the Kepler star field has a planet with a radius only 1.6 that of Earth

Invisible world discovered

Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.
