First scans suggest cigar-shaped space object not an alien craft, say scientists

Scientists analysing a huge cigar-shaped object in space have said initial scans suggest it is not an alien craft.

The celestial body – named Oumuamua – was scanned for radio signals after its shape led researchers to consider the possibility it could be an alien starship.

The Seti project Breakthrough Listen, launched by Russian digital tech mogul Yuri Milner in 2015, used a telescope in West Virginia to listen in on the body.

The Green Bank telescope – the largest fully steerable radio telescope in the world – “listened” to the object across four radio frequency bands spanning one to 12 gigahertz and accumulated more than 90TB of data in two hours.

The first of the four bands has been analysed and has been made available for public inspection.

“Our team is excited to see what additional observations and analyses will reveal.”

Astronomers from the University of Hawaii spotted Oumuamua – named after the Hawaiian term for “scout” or “messenger” – in October passing the Earth at about 85 times the distance to the moon.

It is the first object discovered in the solar system that appears to have originated from another part of the galaxy.

Although thought to be an asteroid, Oumuamua’s elongated cigar shape hundreds of metres in length but only one tenth as wide is highly unusual for a typical space rock.

Travelling at up to 196,000 mph, the object’s high speed also suggests that it is not gravitationally bound to the sun but is destined to head back out of the solar system.

Breakthrough Listen aims to survey a million nearby stars and 100 nearby galaxies looking for alien signals.

Since the 1960s, there have been more than 98 Seti projects around the world, none of which have turned up any convincing evidence of extraterrestrial civilisations.
