Astrobiology, and Realistic Alien Design

Life on another planet may be very different from life familiar to us on Earth, but no matter where it lives, it must have the adaptations needed to survive in the environment it lives in. Consider the scientist in the picture here, looking into a hole in the ice at the arctic north. There is life underwater, in the cold and the dark, hanging upside down attached to frozen ice, which is quite alien and unfamiliar to most of us, and yet native to the Earth.

Visualizing Your Place in the Solar System in Proper Scale

Earth is home. Our Solar System is also home, but it is far larger than most people realize. Part of this is an inability to experience this distance in person: most people never spend much time traveling across the planet Earth in a way to take in the size of all our continents and seas, and our local backyard in outer space is orders of magnitude larger. Another problem can be the way space is presented to our visual minds in scale.
