Earth like exoplanet story telling

As more and more exoplanets (at first) and earth-like exoplanets (eventually) have been discovered, the way thy are described to us has become increasingly sophisticated. Below are embeds of diverse video descriptions that have been very quickly developed and distributed given the freshness of this latest scientific discovery. Note that the practice of very clearly stating that a particular depiction of something that no human has ever seen, or will ever see, as being an artist’s reconstruction has largely fallen by the wayside. Exoplanets are no longer physical features of the universe occassionally glimpsed by astronomers with very fancy Big Science Gear. They are now stories, where almost all the details and even implications are made up.

Oh, no, wait, that’s a plastic bag, never mind.

Happy Anniversary Exoplanets

This month is the twentieth anniversary of the discovery of exoplanets, which are really just planets that are not in our solar system. (Frankly, I dislike the term exoplanet. It is so solarcentric.)

When you think about it, the discovery of planets outside our solar system (we need a word for that) is a special thing. On a graph of how expected and mundane a scientific discovery is vs. how exciting a scientific discovery is, these planets are distant outliers.

For years astronomers and cosmologists and others assumed that stars would generally have planets around them, or at least, this would often be the case. This is all part of the famous Drake Equation, best stated by Carl Sagan using the word “Billions” (with two b’s) over and over again. Like this.

OK, he didn’t really use “Billions” a bunch of times. But he might have.

Anyway, Nature.com has a nice set of infographics on the topic, one of which I’ve posted above. The rest are here.
