Just about 100 years ago, we didn’t know what the surface of Mars and Venus looked like.
Today, we’ve evolved as a technologically advanced species, and there’s no longer a need to make guesses. We can not only observe a planet’s atmosphere but even tell what the celestial bodies in our solar system are made of.

Stay tuned because you are about to find out about this and more!
