Scientists have discovered the most distant and ancient galaxy ever spotted.

By using data collected by the Hubble Space Telescope and observations from the Keck I telescope at the Keck Observatory in Hawaii, astronomers have now confirmed that the galaxy designated z8_GND_5296 formed within 700 million years after the beginning of the universe, making it the oldest and most distant galaxy ever verified.

Because the galaxy is so far from Earth, scientists were able to observe z8_GND_5296 as it would have appeared about 13.1 billion years ago. [How Galaxies are Classified by Type (Infographic)]

Weather and climate conditions in Sounth Africa

A subtropical location, moderated by ocean on three sides of the country and the altitude of the interior plateau, account for the warm temperate conditions so typical of South Africa and so popular with its foreign visitors. South Africa is famous for its sunshine. It's a relatively dry country, with an average annual rainfall of about 464mm (compared to a world average of about 860mm). While the Western Cape gets most of its rainfall in winter, the rest of the country is generally a summer-rainfall region.
