It's more than just a weird shadow this time, planetary geologist Steven Ruff and geobiologist Jack Farmer have seen something on Mars that could indicate life was there. NASA's Spirit Rover took the above image in 2008. They say that the 'cauliflower-like' deposits of minerals seen in this picture could have been formed by microbes.
The area this photo was taken on Mars is thought to have been a center for hot springs and geyser activity. The same kind of mineral shapes have been found in Atacama desert in Chile.
The Atacama desert is often compared to the conditions on Mars and even used as a practice area by NASA for the real thing.
There are just a few basic unwritten rules to life. We all know them.
Well, Reddit decided to write down these unwritten rules. And a thread discussing this topic has given us the essential guide to human life.
Just follow these 10 rules and you'll be good to go. At least, according to the Internet.
You can't really see what happens, but you know it's heroic.
That's State Trooper Eric Devers, who leaps over a guardrail to save a truck driver that had crashed off the highway in Miami County, Ohio. According to the video's description:
An officer with the Ohio State Highway Patrol was honored this week for saving a semi-truck driver's life back in April. Dashcam footage just released shows trooper Eric Devers arrive at the scene of a crash and immediately sprint toward the driver. The trooper found the man still belted into his seat. Shortly after, his eyes rolled back into his head and he stopped breathing, the Ohio State Highway Patrol said.
The truck driver apparently had an atrial fibrillation, which is a quivering or irregular heartbeat that caused him to pass out while driving.
And hey! How cool is CPR? You should learn it yourself and become a hero like that guy there.
Certification and education classes are totally available near you.
It only takes a few hours, go ahead and do it.
FOX News reunited the two men during an emotional television segment.
We'll even forgive Devers for saying a pretty worn cliché.
You can pretty much say anything you want while you're saving someone's life.
