The timing of volcanic eruptions—and the fallout from said eruptions—coincided with the unrest in the Ptolemaic Kingdom.

The fall of the Ptolemaic Kingdom in 30 BC was nothing if not dramatic: there was unrest and uprising in Egypt, the death of Queen Cleopatra VII, and the surge of the Roman Empire. According to researchers addressing the European Geosciences Union General Assembly in April, volcanic eruptions probably had a hand in the fall of the Ptolemaic dynasty as well. That’s right, volcanoes.
A team of volcanologists and historians, including Joseph Manning of Yale and Francis Ludlow of Trinity College Dublin, got together to compare notes. When they studied historical accounts alongside data from ice cores in Greenland and Antarctica (samples acting as chemical roadmaps to the past), they found the timing of eruptions—and the fallout from said eruptions—coincided with the unrest in the Ptolemaic Kingdom.

Now we know a lot more about what was going on in Aldous Huxley’s brain sixty-one years ago.

It’s Christmas Eve, 1955, and renowned writer and intellectual Aldous Huxley is on LSD. He reports his findings in his book The Doors of Perception:
“Each person is at each moment capable of remembering all that has ever happened to him and of perceiving everything that is happening everywhere in the universe.”
Since LSD was synthesized in 1938, the world hasn’t exactly been deprived of first person accounts of its effects (see: Fear and Loathing in Las Vegas, Lucy in the Sky with Diamonds by the Beatles, or this subreddit).
However up until April 11, 2016 the world was deprived of something pretty major: modern scans of the brain high on LSD. Continue reading “LSD, the Brain, and Aldous Huxley”
Chandra was able to observe key changes in Jupiter’s X-ray auroras when a coronal mass ejection hit Jupiter.

In case you thought Jupiter couldn’t get any cooler, a paper in the Journal of Geophysical Research has laid out evidence that solar storms are causing Jupiter’s auroras (think the Northern Lights, the Southern Lights, or that scene from Brother Bear) to brighten by almost eight times their usual brilliance.
The interaction was spotted by NASA’s Chandra X-ray Observatory, a telescope orbiting above the Earth to look for X-ray emissions in that big, old universe of ours.
Since Jupiter’s auroras are actually X-ray auroras, they can’t be spotted by the typical telescope (or by the human eye, if any of you were hoping to plan future vacations there). Chandra was able to observe key changes in Jupiter’s X-ray auroras when a particularly wicked solar storm, or coronal mass ejection (CME), hit Jupiter.
