The search continues for life outside of Earth and Planet Mars remains one of the biggest hotspots when it comes to finding clues of alien life in the universe.

Scientists have so far only scratched the surface of possibilities. For example, what scientists can prove so far is that vast water systems may have existed billions of years ago in the Red Planet, a sign that organic life may have also existed back then. Next, signs of methane gas has been detected this year, with enough levels to get scientists excited. Methane gas is often associated with organic life found underground.

Despite having some serious scientific foundations, both theories has still failed to produce actual evidence that life is being supported in Planet Mars at the moment. Of course, this has not deterred alien theorists and UFOlogists from actually trying to find evidence of life on planet Mars and have in fact, shared some fantastic claims that could shed light to the mystery of the Red Planet.

One of the most popular “discoveries” happened last year when NASA’s Mars rover Curiosity stumbled on what looked like a nice, shiny nugget on the Martian surface. According to a report from CNET, NASA’s Curiosity team posted the discovery in its mission blog and nicknamed the shiny object, “Little Colonsay.”

The shiny object was captured by the Curiosity’s ChemCam and even has a close-up view of the object.

"The planning team thinks it might be a meteorite because it is so shiny. But looks can deceive, and proof will only come from the chemistry," Curiosity team member Susanne Schwenzer said.

The object actually remains a mystery upto today and many conspiracy theorists are claiming that this could be a piece of advance tech left by advanced alien civilizations who once ruled over the Red Planet.

This is not the first time that Curiosity has stumbled on what seemed like alien hardware. When the rover successfully arrived on Mars, it stumbled on another shiny artifact that turned out to be a piece of plastic from Curiosity itself.

Another discover was what looked like a metal flake also found on the surface of Mars which seemed like another evidence pointing to advance tech from another life form. It turned out to be a piece of Martian rock and was acknowledged by NASA.

The rover’s ChemCam is composed of a number of instruments that includes a camera, spectographs and a laser that helps the U.S. space agency analyze the composition of the Red Planet’s rocks and soil.
