The cigar-shaped space rock first shot past Earth two months ago and caused excitement that it may be an alien space ship.

The Breakthrough Listen project have announced that they will be conducting more tests on the strangely shaped space object after the initial investigation revealed no sign of alien life.

Andrew Siemion, Director of the Berkeley SETI (Search for Extraterrestrial Intelligence) Research Center in California said: “Our team is excited to see what additional observations and analyses will reveal.”

The object’s official name is A/2017 UI but has been dubbed “Oumuamua”, which loosely means “a messenger that reaches from the distant past” in Hawaiian.

The bizarre rock is believed to have been wandering among the stars for hundreds of millions of years and it is the first foreign object in our solar system to be spotted.

It was spotted by the Pan-STARRS1 telescope in Hawaii on October 19 and travelling at about 95,000 kilometres per hour.

The space organisation also ran more radio test on Wednesday that might provide more information about Oumuamua.

The six hour observation gathered 90 terabytes of data and scientist will now examine the information the test gathered.

A spokesman for Breakthrough Listen said: “A search for signals that may be of artificial origin has begun, but despite the impressive computational power of the Breakthrough Listen computing cluster at Green Bank, the large data volumes mean that this will take some time to complete.”

Three more observations of the unusual space rock will take lace in coming months.

Mr Siemion added: “It is great to see data pouring in from observations of this novel and interesting source.”

Oumuamua is the first time that scientists have been able to analyse an interstellar asteroid and their findings could provide previously unknown information about other solar systems and galaxies.

So far more than $100million (£74million) has been spent researching the space rock.
