Scientists Discover Super Earth

Employing  the seldom-used gravitational lensing technique, scientists has discovered what they are calling a “Super Earth,” smack in the middle of our Milky Way Galaxy, near the galactic bulge. Anton Petrov, host of “What Da Math,” says the discovery was an extremely rare event, since the host star of the planet is a red dwarf, which are usually small and dim. The star is approximately 12 percent the mass of the sun and the Super Earth is about four masses of Earth. “We don’t really know if it’s a gas world, but it’s somewhat more likely to be an unusual, somewhat ice-like planet with similar conditions to maybe Neptune or Earth.”

NASA’s New Frontier

NASA is embarking on a bold, new program to peer deeper into space, using a technique called gravitational lensing. Astronauts have already put the tool to work to detect the most distant galaxy ever, and hope to continue exploration. Join Hank Green for details on the program and for his review of the movie Gravity in this edition of “SciShow.”
