This is a thread for any news that relates to the discovery of alien life in general and intelligent life in particular on any of thousands of newly discovered exoplanets.
For starters, here is an excellent video that once more reveals how lucky we had been. Video is by well known Youtuber Scott Manley who's known for his rocket technology videos. Here he analyses how big chemical rocket one needs relative to the size of a planet. For example, while on Earth Saturn V can take you to the Moon, on an exoplanet that is a double the Earth diameter it Saturn V wouldn't be able even to get you into the orbit.
That directly means, that civilizations on an exoplanet larger than Earth, would take much longer to start exploring its solar system. So, relatively speaking, we've been lucky that Earth is neither too big to take off into orbit, neither too small to have insuficient amount of metals to make the rockets.
