Mankind's exploration of the universe shows our deep curiosity and desire to understand space. Starting with basic stargazing, we've built powerful telescopes and sent spacecraft to learn more about the cosmos. We've landed on the moon, explored Mars, and launched telescopes like Hubble that let us see distant galaxies. As our technology gets better, we're getting closer to discovering more about the universe and even finding other forms of life. ►Subscribe – http://goo.gl/wpc2Q1
