A set of 3.4-billion-year-old rocks that scientists think contain the oldest known microbial fossils may show that life on Earth preceded oxygen

A microbial bacteria fossil may be proof of life before oxygen on Earth 3.4 billion years ago. The Strelley Pool Formation in Western Australia was once a beach but is now more than 100 Km inland and houses stromatolites, which have been preserved there.

The oldest known fossils on earth, discovered in Australia, suggest that similar sulfur-based forms of life could exist on other planets like mars where oxygen levels are low or no existent.

Getting hints from the remainder of 3.4-billion-year-old rocks, a team of geologists have unearthed possibly the oldest known fossils ever, which may unfold the mysteries around the early development of life on Earth. v

In a letter sent to SpaceX founder Elon Musk, PETA has urged the sending of only vegan flights during any future SpaceX missions to Mars.

A man in New Brunswick, Canada, recorded a video in which fast moving clouds take the shape of a face that resembles Abraham Lincoln.

NASA is preparing to launch a more advanced rover to delve even deeper into the history of Mars, just as its current rover is hitting its stride.

NASA's Mars Exploration Rover (MES) Opportunity after painstakingly covering a 13-mile journey in three years has reached the Red Planet's Endeavor crater.

NASA is pushing the boundaries of technology as it readies its next mission to Mars, loading up its fourth Mars Rover with nearly a dozen instruments and employing an innovative but risky landing procedure.

NASA is moving closer to launching its 4th rover on a mission to Mars that will investigate whether Mars is, or whether it has been hospitable to microbial life.

NASA created a deep space mission department to oversee deep space manned mission explorations such as traveling to space rocks and Mars.

NASA has opened a new office called the "Human Exploration and Operations Mission Directorate" to oversee deep space manned missions. NASA was charged by Uncle Sam to put astronauts on an asteriod by 2025, and Mars by mid 2030s.

Mars Rover Opportunity has reached its next destination, the massive Endeavour crater.

As NASA?s Mars Exploration Rover Opportunity landed on its new site, Endeavour crater, on the Martian surface on August 9, scientists assumed it started paving way towards possible future human missions to planet Mars.

After a nearly three year journey, NASA's Mars rover "Opportunity" has reached its destination at a edge of a crater-rim , sending back photographs of never seen before rocks.

NASA reaches its destination, the Endeavour crater, where it will study rocks and terrains never seen by the human eye.

The Mars rover Opportunity is nearing the end of a three year voyage to the Endeavor crater, a massive formation that has been Opportunity's destination since it left the smaller Victoria crater in August of 2008.

NASA's Mars Exploration Rover Opportunity will revisit the rim of Endeavour crater on Mars, where its rover twin Spirit finished its mission in May.

Start the slideshow to view images from NASA?s past Mars expeditions suggesting evidence of water on the Martian surface.

Scientists have discovered flowing salt water on Mars, which has sparked conversations about potential alien life within the planet's surface. The images sent from NASA's orbiter unveiled flowing waters descending down from rocky slopes.

The mysterious dark lines in question were observed to be occurring seasonally as the ground they came from was exposed to warmer temperatures. The line would then disappear later as temperatures dropped, causing the scientists to speculate that briny water was causing the flows. The discovery could be a huge breakthrough in the search for whether or not liquid water ever existed on the surface of Mars.
