What does the Earth look like during a total solar eclipse? It appears dark in the region where people see the eclipse, because that's where the shadow of the Moon falls. The shadow spot actually shoots across the Earth at nearly 2,000 kilometers per hour, darkening locations in its path for only a few minutes before moving on. The featured image shows the Earth during the total solar eclipse of 2006 March, as seen from the International Space Station. On Friday the Moon will move in front of the Sun once again, casting another distorted circular shadow that, this time, will zip over part of the north Atlantic Ocean.

The hunt for alien life has been given a boost after scientists discovered a habitable planet almost the same size as Earth.

Astronomer Thomas Barclay from Nasa's Ames Research Centre in California made the discovery using data collected by the Kepler space telescope.

The unnamed planet was found orbiting an unidentified star in its so-called Goldilocks zone - a region around the star that emits just enough energy, light and temperature for liquid surface water to appear.

The lake appears to be a normal one during fall, winter, and a small portion of spring; but during the summer, most of the lake becomes evaporated. Dozens upon dozens of crater-like mineral deposits rest at the bottom of the lake and become visible during the warm weather. The mineral deposits span about 25 feet on average and contain many different concentrations of magnesium sulfate, and calcium/sodium phosphates, which gives them a distinct yellow, orange, green, or blue color.

Altogether, data beamed back from numerous missions suggest that no place on the moon would be a pleasant place to live, at least compared with Earth. Lunar days stretch for about 14 Earth days with average temperatures of 253 degrees Fahrenheit (123 degrees Celsius), while lunar nights also last 14 Earth days (due to the moon's rotation) and maintain a frigid cold of minus 387 degrees Fahrenheit (minus 233 degrees Celsius).

"About the only place we could build a base that wouldn't have to deal with these extremes is, oddly enough, near the lunar poles," said Rick Elphic, project scientist for NASA's LADEE probe, which studied the moon's atmosphere and dust environment before performing a planned crash into the natural satellitein April 2014. These areas likely store vast amounts of water-ice and enjoy low levels of light from the sun for several months at a time.
