So if this means what I think it means, Dr John Brandenburg believes aliens blew up Martians.

Brandenburg presented "Evidence of a Massive Thermonuclear Explosion on Mars in the Past, The Cydonian Hypothesis and Fermi's Paradox," at the 2014 Annual Fall Meeting of the American Physical Society in Monmouth, Illinois.

Brandenburg is a plasma physicist and an expert in propulsion technologies. He theorizes; there are worlds in our galaxy not friendly to “young, noisy, civilizations” like what he says existed on mars.

The good doctor claims groups called the Cydonians and Utopians were wiped out in separate nuclear attacks.

Brandenburg points to high levels of Xenon-129 in the atmosphere.

"Given the large amount of atomic isotopes in Mars atmosphere resembling those from hydrogen bomb tests on Earth, Mars may present an example of civilization wiped out by a nuclear attack from space," Brandenburg writes.

He believes the planets red color provides further proof. Before you laugh it all off, Brandenburg warns Earth could be next on the bad aliens list.
