Does space affect an astronaut’s digestion?
We chew our food, swallow it, and our stomach goes to work on digesting! Our bodies absorb the nutrients they need and then we poop out the rest. Here on Earth, the whole process takes somewhere between one to three days. But what about in space? Do astronauts digest food as quickly as they do on Earth? We reached out to space scientist and science communicator Maggie Aderin-Pocock to get the answer!Got a question you’re chewing on?

Why is the moon white and why does it have different shapes?
Some planets have lots of moons. Others have none. Earth has just one moon, but it’s a really great one. It can glow bright and white and sometimes it’s shaped like a big round ball. Other times it’s skinny like the white tip of a fingernail. Makes you wonder, why does the moon look the way it does? We asked Preston Dyches from NASA’s Jet Propulsion Laboratory to help us find the answer.Got a question orbiting around your brain?
