On what would have been his 78th birthday, here’s a selection of Sagan-inspired GIFs to honor the late sage of science and science popularization. The garden of our mind would not grow as rich if it weren’t for people like Carl, and without him, many people like me certainly wouldn’t be talking science at you all the time. He’s my greatest inspiration as a teacher, and I don’t think I’m the only one.
What’s that? You want more than just some GIFs? Okay! Click here or here to find pretty much all of my Carl Sagan posts, ever. My apologies to your productivity.
Light from an alien “super-Earth” twice the size of our own Earth has been detected by a NASA space telescope for the first time in what astronomers are calling a historic achievement.
NASA’s infrared Spitzer Space Telescope spotted light from the alien planet 55 Cancri e, which orbits a star 41 light-years from Earth. A day on the extrasolar planet lasts just 18 hours.
The planet 55 Cancri e was first discovered in 2004 and is not a habitable world. Instead, it is known as a super-Earth because of its size: The world is about twice the width of Earth and is super-dense, with about eight times the mass of Earth.
