Gemini Planet Imager
Using the Gemini Planet Imager, scientists have discovered a disc-shaped bright ring of debris surrounding a nearby Sun-like star called HD 115600, a planetary system that resembles our own solar system in its infancy. This discovery may help scientists to understand how our solar system formed and developed billions of years ago.
The researchers believe that the discovery of Earth 2.0 (a planet very similar to ours) will be possible soon, it is only a matter of time. Dr. Franck Marchis (SETI Institute) has a date for this event. He believes that we will find a planet like ours up to 2024.
