31 Days of Planets: 55 Cancri e

Day 11

55 Cancri e is an exciting planet for multiple reasons. It orbits the sun-like star 55 Cancri A (very creative naming convention, I know). A sun-like star! You know what that means? There may be the possibility of an Earth-like planet which orbits a sun-like star, and an Earth-like planet may have Earth-like life... Aliens would be the best Christmas present ever.

In October 2012, they announced that this planet is a carbon planet. If the planet is composed largely of carbon, and is regularly subjected to high temperatures (over 3000 degrees F) and high pressure, then the carbon on this planet could be largely composed of diamond. A diamond planet! Amazing.

Imagine the views - so much sparkling! Of course, rough diamonds are not nearly as sparkly as cut diamonds, but it's fun to imagine... castles cut out of the ground, glittering turrets and impenetrable glowing walls; rolling hills of graphite, and kings who are never at a loss for diamond pencils.

And here it is - an artist's conception of the diamond planet orbiting its sun:



And the diamond core - which in real life is probably not so sparkly -


In conclusion - a diamond ring might be nice, but a diamond planet would be amazing.

Watching the Universe Expand

They say the universe is expanding, faster than we ever imagined possible; so fast, in fact, that the end will come with planet-sized cubes of ice and the simultaneous explosions of a thousand million unopened cans of soda. My aunt told me that she plans to dress in layers. It's a rushing train, speeding by us at the speed of sound, at the speed of light, at the speed of time.

I don't plan to miss the show. One day I will be writing to you from the window of a space ship, or from a space suit on the moon. Of course, in order to accomplish this, I either need to acquire a lot of money in a short period of time, or wait until you are all up there with me, until outer space is next best vacation spot. So for now I will watch from my living room as one star floats by at a time.

Today I saw a "huge 'waterworld' [that] has boiling oceans hundreds of times as deep as Earth's"*. A world where one year lasts only eighteen hours, a world in which water exists in a confused state of vapor and liquid, and makes up 20% of the mass of the planet. A world in a family of five, orbiting 55 Cancri A, 40 light years from Earth. Another planet, another beautiful, unreachable world. And when the universe explodes, it will rain water in some confused state, but by the time it reaches me, only shards of ice will remain.
