NASA discovers planet similar to Earth

NASA believes it's found the most Earth-like planet yet. Kepler 452-b is named for NASA's Kepler telescope. The space agency calls it an "older, bigger cousin to Earth." Lee Billings, space and physics editor of Scientific American, joins “CBS This Morning” to discuss the planet.

This blue block is Aerogel, the lightest solid material on Earth. It is created by removing the liquid from a silica gel and replacing it with gas, creating a foam that is almost entirely air. Despite being lighter than a marshmallow, it is such an incredible insulator that NASA uses it to protect Mars rovers from freezing, and it protects this flower from the intense heat of a Bunsen burner just an inch away. #physics #science #aerogel #frozensmoke #engineering

NASA Lost a Giant Asteroid and Nobody Noticed! Back in 2007, astronomers discovered an asteroid named 2007 FT3 and initial calculations suggested it could be on a collision course with Earth. But just a day later, the asteroid vanished without a trace! Even with just a day’s worth of data, NASA managed to predict 89 different ways this asteroid could swing by and hit us. Could they be right? And… What with all the strange leaked documents floating around?!! #physics #science #learning #facts #ad
