A Gamma Ray Burst In The 8th Century?

Did A Gamma-Ray Burst Hit Earth During The Middle Ages?

In Ends of the World: Gamma-Ray Bursts, I raised the possibility that millions of years ago, Earth may have experienced a catastrophic gamma-ray burst, an immense beam of energy that forms when high-mass stars collapse, or after a collision between binary neutron stars. Well, a new study claims that it actually may have happened, but …

Double Solar Eruption, All The Way ‘Cross The Sky!

The Sun unleashed what many are calling a “solar tsunami” on Friday, November 16, 2012, with two massive eruptions occurring within four hours. The action was caught by NASA’s space-bound Solar Dynamics Observatory. Luckily, the eruption wasn’t aimed at Earth, so we shouldn’t have anything to worry about. Yet.

An aurora is a natural phenomenon in which charged particles from solar winds and the magnetosphere collide with atoms in Earth’s upper atmosphere. Luminous swirls appear in the sky, shades of green and sometimes red or blue, painting the night in an alien glow. In the north, this phenomenon is called the Aurora Borealis, or …

An incredible coronal mass ejection erupted from the Sun on August 31, 2012, shooting out “a long filament of solar material” that actually connected with “Earth’s magnetic environment.” Or, in other words, a solar whip. Just like Indiana Jones, right?

Even More X-Class Solar Flares? Hold On To Your Butts

Sooner or later, I’ll catch an aurora. Sure, living in the Midwest, that might be a bit difficult. But if the Sun keeps throwing solar fastballs at Earth, you figure eventually we’ll get a light show down here. In fact, I might get the chance sooner than I thought. It’s all courtesy our friend Sunspot …

Most Powerful Solar Flare of 2012 Erupted On Tuesday

A few days ago, the Sun unleashed a powerful X1.1-class solar flare. It blasted out into space, missing Earth but causing scientists to wonder if it was a prelude of even stronger activity to come. Apparently, they were right. Yesterday, at 7:02 p.m. EST, two more X-class flares erupted within hours of each other. The …
