Wheel robot is equipped internal laboratory has been on Mars since August last year. The red planet robot explorers have reportedly found an ancient riverbed on the surface of Mars.

Reported by Softpedia, Friday (05/31/2013), NASA announced that Curiosity has found evidence of an ancient riverbed in the red planet's surface. Pictures captured this sophisticated robot allows for scientists to analyze rock formations

In addition to analyzing rock formations, they also will determine that the findings Curiosity is part of the riverbed that once existed on Mars. Researchers identified several sites on Mars, where Curiosity has captured images that site during the first 40 days mission.

Scientists say, one of the three stones that resemble asphalt, which is called the 'Goulburn' is really the next Curiosity landing site. While two other stones, 'Link' and 'Hottah' is approximately 50 and 100 meters from the Curiosity landing site.

of the Planetary Science Institute reveals, ancient riverbeds on Mars exactly on Earth.

He explained that there are many signs that rock and gravel that exists on Mars is an ancient riverbed. Researchers looked up 515 stone and gravel. Large pebbles grouped, showing movement and then followed by some sand like on Earth.

With the arrangement of pebbles and small stones at the size of these, the scientists determine the speed of the former ancient river system is approximately one meter per second. Scientists also estimate the depth of this ancient river must reach the ankle or hip adult humans.

Researchers find beads made from 5,300 Year-Old Meteorite

Ancient Egyptians known to have a were very advanced civilization. Even to make jewelry they do not messing around, using meteorites as feedstock. Ancient Egyptians use stones to make jewelry metals sky. Team of archaeologists from the Open University in the UK confirmed this. They find a beaded necklace 5,300-year-old in the ancient Egyptian burial site.

Necklace made with iron from the meteorite. Evidence of iron smelting activity recorded in Egypt began in the 6th century BC. However necklace artifacts in the ancient cemetery area was much older, including the tomb of Tutankhamun.

Previous analyzes of the oldest of nine iron beads in a cemetery near the River Nile can not prove their origin. Now researchers have analyzed one bead jewelry and concluded that it was made from meteorites. Bead surface has a low nickel content, but part of it containing high nickel contained in meteorites.

But the most valid evidence is a typical crystal structure known as a Widmanstatten pattern is only formed when iron and nickel cools very slowly, as seen in meteoroids.
