Rosetta Results: Comets "Did Not Bring Water To Earth"

Posted by samzenpus on Wednesday December 10, 2014 @08:05PM from the wet-of-space dept.

An anonymous reader writes with findings from the Rosetta mission which suggests water on Earth probably came from asteroids, and not comets."Scientists have dealt a blow to the theory that most water on Earth came from comets. Results from Europe's Rosetta mission, which made history by landing on Comet 67P in November, shows the water on the icy mass is unlike that on our planet. The results are published in the journal Science. The authors conclude it is more likely that the water came from asteroids, but other scientists say more data is needed before comets can be ruled out."

They got it wrong. The dry comets are lighter and so are still flying around. The wet ones were heavier and so fell to Earth.

  That whooshing sound you heard was not a comet passing over your head, it was the joke.
