Video: This planet of ours, it ain't gonna last forever. And though who the heck knows what's going to happen to the world that far off into the future (or even after November 8), Life Noggin decided to conduct a little brain exercise about how we could convert a planet like Mars or Venus, or a moon like Europa, into a second Earth.

If you could hop in a time-travelling spacecraft, go back three billion years and land any place in our solar system, where would you want to end up? Earth, with its barren continents and unbreathable atmosphere? Or Mars, a chillier version its big brother? Wait, what about Venus?

Video: If you want to feel small and get a sense for the awesomely overwhelming scale of the universe and all of its planets and stars and empty space, watch this star size comparison video. It starts with our Moon and then sizes up to planets in our solar system in a line up while also looping in other rocky planets and bright stars to show us how we compare (we don't).

Neptune, the farthest named planet in our solar system (sorry Pluto), is unusual in a lot of ways. One rotation around the sun lasts about 165 Earth years, and each season is around 40 Earth years. Another noteworthy thing about the planet is its atmosphere, which has a fluctuating brightness.

Image Cache: If you want to see beautiful auroras, forget Alaska, Canada and Iceland — check out Jupiter. At the gas giant's north pole, the most powerful and luminous northern lights in the solar system shimmer and glow in an endless geomagnetic storm that's larger than our entire planet.

Video: Our solar system is weird. Not only because we're unique little snowflakes on a blue marble called Earth, but because other stars usually have their giant arse planets (that is, their Jupiter) orbiting them at a much closer distance. This is really common in other systems! Our Jupiter, however, doesn't work like that. Why?

Video: It's the circle of life! Well, not quite but sort of. This great short animation from production company Chromosphere highlights the world we live in and the worlds beyond our world through the clever use of circles. Right smack dab in the middle of the frame, watch as the circles transform into animals and planets and space objects and natural phenomena and the human body and more. It's a really well done animation.
