No alien signals from new asteroid, say researchers

No alien signals have been detected from an interstellar, cigar-shaped space rock discovered traveling through our Solar System in October, researchers listening for evidence of extraterrestrial technology said Thursday.

The object, dubbed Oumuamua, was spotted by several telescopes two months ago.

Given its unusual trajectory, surprised researchers immediately concluded it was from beyond our planetary system – the first interstellar object ever identified in our midst.

The rock is thought to be about 400 meters long and is also thin - only about 40 m wide - a never-before-seen shape for an asteroid.

After its discovery was announced last month, a project called Breakthrough Listen, dedicated to finding signs of extraterrestrial intelligence, said it would study the rock for artificial signals.

"No such signals have been detected" by its network of telescopes, the project said Thursday, adding, "the analysis is not yet complete."

Oumuamua is a Hawaiian name meaning "messenger" or "scout". It may have been traveling through space for hundreds of millions, even billions of years.

Prior to its discovery, none of the 750,000-odd known asteroids and comets in the Solar System were thought to have originated elsewhere.

"Oumuamua is most likely an asteroid, ejected from its host star in some chaotic event billions of years ago and finding its way to our solar system by chance," said Andrew Siemion of the University of California Berkeley who heads the Breakthrough Listen laboratory.

According to NASA, the object is traveling at about 38.3 kilometers per second relative to the Sun. It is about 200 million kilometers from Earth.

It passed Mars' orbit in November and will pass by that of Jupiter in May next year, before exiting beyond Saturn's orbit in January 2019.
