"if it had hit, we would still be picking up the pieces," said daniel baker, of the laboratory for atmospheric and space physics at the university of Colorado. "i have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did. if the eruption had occurred only one week earlier, Earth would have been in the line of fire."

with colleagues from nasa and other universities, baker has been studying the disaster that wasn't. if the coronal mass ejection (cme) had hit the Earth, it would have disabled "everything that plugs into a wall socket".

there would have been major disruption to all satellite communications and electrical fluctuations that could have blown out transformers in power grids. most people wouldn't have been able to turn on a tap or flush a toilet because urban water supplies largely rely on electricity.

This rare form of parasitic meningitis—primary amebic meningoencephalitis (PAM)—is caused by an amoeba called Naegleria fowleri. That microscopic amoeba—part of the class of life called protozoans—is a naturally occurring organism that normally feeds on bacteria and tends to live in the sedimentary layer of warm lakes and ponds.
