There’s finally proof that Earth-like planets can exist outside our solar system: Scientists have managed to measure the mass of exoplanet COROT-7b, revealing that it’s the first exoplanet with a confirmed density similar to our own.
“This is a day we’ve been waiting for for a long time,” said exoplanet researcher Sara Seager of the Massachusettes Institute of Technology, who was not involved in the research. “It’s the first definitive rocky world beyond our solar system, and it’s opening a new gate for our research. We’re really, really excited about it.”
