Kepler-78b: The Earth-Like Planet That Shouldn't Exist 110
astroengine writes "Kepler-78b may be an exoplanet notable for being approximately Earth-sized and likely possessing a rocky surface plus iron core, but that's where any similarity to our planet ends. It has an extremely tight orbit around sun-like star Kepler-78, completing one 'year' in only 8.5 hours. It orbits so close in fact that the alien world's surface temperature soars to 2,000 degrees hotter than Earth's. Referring to Kepler-78b as a 'rocky' world is therefore a misnomer — it's a hellish lava world. But this is just a side-show to the real conundrum behind Kepler-78b: It shouldn't exist at all. 'This planet is a complete mystery,' said astronomer David Latham of the Harvard-Smithsonian Center for Astrophysics (CfA) in a press release. 'We don't know how it formed or how it got to where it is today. What we do know is that it's not going to last forever.'"

I'm not so sure about that. From TFA:
That is in opposition to this: [nationalgeographic.com]
TFA is framing the question in a sensational way. What the scientists are saying is "this is an exciting puzzle, it shouldn't happen according to what we know.

Part of the problem is that many of the planetary system models have been developed with a sample size of one. That unfortunately skews the results of any such models. Now that there are literally hundreds of planetary systems to examine where the astrophysicists who make up these models can look at actual stellar systems to see how those models compare to reality, I'm sure there are going to be some changes to those models and some new theories put forward.
As usual, the science press is making up stuff to sensationalize a situation that is admittedly still unknown simply because it takes time to digest all of this new information. I don't think this is a reporter trying to attribute this to the supernatural, but they are trying to make what is otherwise dull news sound interesting.

Yeah, when scientists say "This shouldn't happen according to current models", they are really saying "Holy shit, this is awesome! We get to come up with new models!".
Meanwhile, the mainstream media hears that and reports it either as "Scientists say this shouldn't happen. The universe is fucked up" or "Scientists say this shouldn't happen. Science is fucked up" depending on their political bent.
