As Man probes ever deeper into the mysteries of the Universe, his search seems to yield more questions than answers. Some of the most mysterious phenomena discovered in space are dark matter and dark energy.

Approximately 80 per cent of the mass in known Universe is made up of "dark matter," a strange and intangible substance that yet scientists have not been able to identify or observe directly. Dark matter is not visible to the naked eye, and does not emit light or energy.

So how do we know it even exists?

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.

The quest to confirm the existence of liquids on Mars has been ongoing for decades; it was known to host water billions of years ago and water is has been found to exist there in the form of ice, but the latest images from NASA’s Mars Reconnaissance Orbiter (MRO) indicate that water may not only be present, but running down the Martian hills.

Newly released photographs from a variety of different locations across the southern latitudes of the Red Planet show dark streaks, known as ”recurring slope lineae” or RSL, that appear to course down inclines in the same manner as flowing liquid.
