Saturday evening stargazers were treated to one of the trippiest natural phenomenons Earth has to offer: a naked eye-visible aurora borealis. The "northern lights," as they are often called, originate with our sun. Solar storms that occur there emit streams of charged particles which help to trigger the unusual light show once they reach Earth. SEE ALSO: The mystery of panda's fur color is finally solved The magnetic fields emanating from our north and south poles pull the charged particles down into our upper (and sometimes lower) atmosphere, where some of them collide with the neutral particles that reside there. The result of this collision is a beautiful glowing sky, though it's usually visible only at higher latitudes. In the Northern Hemisphere it's an "aurora borealis" and in the Southern Hemisphere it's an "aurora australis." Saturday evening's aurora borealis extended further south than is normal for these events, which meant it was visible in the northern U.S., Canada, and parts of Europe. It was the result of the sun spitting out a large burst of plasma on May 23, an event referred to as a Coronal Mass Ejection (CME). The internet expressed its thanks for the cosmic light show in the only way it knows how: social media shares enhanced by stunning photography. WOW! Northern Lights seen tonight from Cape Cod, Massachusetts.

By Tom Allard MARAWI CITY, Philippines (Reuters) - Bodies of what appeared to be executed civilians were found in a ravine outside a besieged Philippine city on Sunday as a six-day occupation by Islamist rebels fending off a military onslaught took a more sinister turn. The eight dead, most of them shot in the head and some with hands tied behind their backs, were laborers who were stopped by Islamic State-linked militants on the outskirts of Marawi City while trying to flee clashes, according to police. The discovery confirms days of speculation that Maute rebels had killed civilians during a takeover of Marawi, that the military believes is aimed at winning the Maute recognition from the Islamic State as a Southeast Asian affiliate.
Iran's supreme leader Ayatollah Ali Khamenei launched a fierce attack against regional rival Saudi Arabia, saying it was being pumped "like a milking cow" by "infidel" Americans. "These people (the Saudis) appear to believe in the Koran... but in practice they act against its teachings," Khamenei said at a meeting on Saturday to mark the start of the holy month of Ramadan. "But in reality there is no closeness and, as the Americans have said, they are just there to pump them for money like a milking cow, and later slaughter them," he added.
Islamist militants locked in street-to-street battles with security forces in a southern Philippine city have killed 19 civilians, the military said Sunday, bringing the official death toll from nearly a week of fighting to at least 85. The violence prompted President Rodrigo Duterte to declare martial law on Tuesday across the southern third of the Philippines to quell what he said was a fast-growing threat of militants linked to the Islamic State (IS) group.
