Can a solar flare kill us?

Solar Flare Headed to Mars



A solar flare is headed for Mars, resulting in the Curiosity rover needing to be powered down.  Curiosity's little brother, Opportunity, is still functioning as normal on the red planet.  Unfortunately, Curiosity won't be able to sample the level of solar particles or retrieve a sample of the radiation that the solar flare is throwing at the planet.

New Gamma Burst that Impacted Earth Discovered



A new discovery of an enormous explosion in space, sending out high levels of radiation is believed to have impacted earth during the rule of Emperor Charlemagne, between 774 and 775 AD.  Scientists have discovered this impact by studying the rings in cedar trees, which point that this phenomena occurred during medieval times.  This explosion is not believed to have been caused by our own sun, but more likely a collision between two stars or two black holes that were inside our own Milky Way galaxy.  These newly discovered tree rings have given scientists their best ‘guess’ at what might have occurred during that era.
