Mysterious interstellar object caught on camera as scientist says it could be an alien spacecraft

A mysterious interstellar object hurtling through the solar system has been caught on camera for the first time.

First spotted by NASA on July 1, scientists from around the world have now confirmed that this unexpected visitor has travelled through space from a distant star. 

Officially titled 3I/ATLAS, the rare interloper is 12 miles (20km) long and hurtling towards the sun at 135,000 miles per hour.
