As researchers learn more and more about the planet Mars, the likelihood of life having developed on the Red Planet increases. Two separate discoveries, one involving the discovery of what may be planet Earth’s oldest fossils, and another that shows that Mars may have had more water on its surface than anticipated, reinforce the idea of life having once thrived on the Martian surface.

Astronomers are warning us that asteroid 2014 DX110 is on target to hurtle between the Earth and the Moon on Wednesday, passing close to our planet at a distance of just 217,000 miles (350,000km).

At 98ft (30m), 2014 DX110 is a relatively large object belonging to the Apollo class asteroid group, a class of Earth-crossing objects that pose a potential threat of impact. Scientists are currently aware of 240 Apollo asteroids, but it is thought that there could be at least 2000 Earth-crossers with diameters of 1 km or larger. If one of these giants hit Earth, it could carve out a crater about 10-20 times its own size.

Fragments of a meteorite narrowly missed hitting 10-year-old Anthony Elliss-Galati in Perth, Australia, then smashed into his driveway. Another meteorite made a crater in a parking lot near Detroit, but no one saw it because they’d all left work when it hit. Since the lot was empty, it didn’t hit anyone’s car (or anyone’s head).

Anthony’s mother says, "I heard something hit the [pavement] and then Anthony came inside and said there were rocks coming out of the sky. He then handed me a piece and it didn’t look like a normal rock?it was dull on the inside and silver on the outside and looked as if it had melted. Anthony said he had seen it coming across the park and had to duck down behind my car to avoid being hit by it."

Scientists have announced that they have discovered magnetic crystals inside a 4 billion year old Martian meteorite that landed in Antarctica about 13,000 years ago. On earth, this type of crystal is only produced by microscopic bacteria.This is strong evidence for the existence of at least bacterial life on Mars.

This magnetic compound is called Magnetite and is used in audio and video tapes. It is created by a type of bacteriathat assembles the crystals atom by atom, producing crystals that are free from defects. This bacteria is commonly foundin water here on Earth.

“Finding this type of magnetic crystal in any material from another planet is an amazing and important finding,” saidDr. Dennis Bazylinski, a geobiologist at Iowa State University.
