Some interesting news from space these days, and for once didn’t have to do with Mars. For many years, scientists at NASA and other space agencies have known about 55 Cancri e, an extrasolar planet that orbits the Sun-like star 55 Cancri A that is approximately 41 years from our system. Up until recently, it was believed that this planet was a “Super-Earth”, a planet many times the mass of Earth composed of granite.
Recently, however, scientists have announced that the planet may in fact be composed of carbon. That means, in essence, that the surface is composed of graphite and diamond. These findings come as part of a study that was released by the Institut de Recherche en Astrophysique et Planetologie in Toulouse, France. Nikku Madhusudhan, a Yale researcher who was part of the project, estimates that at least a third of the planet’s mass, the equivalent of about three Earth masses, could be diamond.
Imagine that, three entire Earth’s worth of diamonds! The mind reels at the staggering amount of wealth and opulence that this planet could produce, if only human mining teams were able to access it. However, surface conditions might complicate that a little. According to that same report, the planet is incredibly hot, with temperatures on its surface reaching 1,648 Celsius (3,900 degrees Fahrenheit). Not exactly cozy, by Earth standards.
Speaking of which, this is another aspect of the discovery which is proving exciting. According to Madhusudhan, “This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth,” adding that the discovery of the carbon-rich planet meant distant rocky planets could no longer be assumed to have chemical constituents, interiors, atmospheres, or biologies similar to Earth. And he’s not alone is suspecting that discoveries like this are just the tip of the iceberg, as we work our way further out into the universe and discover more examples of strange and exotic exoplanets.
