Watch how earth looks from space

Everyone has dreamt of looking at the 'Blue Plant' from up there. Now you can watch earth live - as viewed from space.

NASA is now live-streaming views of earth from space captured by four commercial high-definition video cameras that were installed on the exterior of the International Space Station last month.

If you find the screen black, do not worry - the space station is likely just on the earth's night side.

The station completes one orbit every 90 minutes, so you will not have to wait too long.

"The cameras are enclosed in a temperature-specific housing and are exposed to the harsh radiation of space," NASA officials said in a statement.

"Analysis of the effect of space on the video quality, over the time HDEV is operational, may help engineers decide which cameras are the best types to use on future missions," the statement read.

The webcast of HD Earth video feed is also on space.com and will be accompanied by other live space broadcasts.
