NASA's brand-new Mars rover is on the hunt for alien life, and with the help of cutting-edge engineering, scientists embark on a search for fossilized remains, which might prove the Red Planet was once home to a vast ocean and extraterrestrial life.
In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s temperature, density, spin, motion, and chemical composition.
The universe is a dangerous place, and we explore the deadliest spots in the cosmos. Between earth and the edge of the universe, there are a million ways to die, and our crash test dummy is on a mission to reveal the worst.
One of NASA's most ambitious missions, OSIRIS-REx, is investigating the asteroid Bennu in more detail than ever before, revealing how space rocks can kick-start life on other planets and how they could possibly hold answers to the secrets of the Solar System.
