A large cluster of objects in space look like something you would “expect an alien civilization to build,” astronomers have said.
Jason Wright, an astronomer from Penn State University, is set to publish a report on the “bizarre” star system – suggesting objects could be a “swarm of mega-structures.”
He told The Independent: “I can’t figure this thing out and that’s why it’s so interesting, so cool – it just doesn’t seem to make sense.”
Speaking to the Atlantic, Mr. Wright said: “Aliens should always be the very last hypothesis you consider, but this looks like something you would expect an alien civilization to build. I was fascinated by how crazy it looked.”
But KIC 8462852 was emitting a stranger light pattern than any of the other stars in Kepler’s search for habitable planets. Kepler works by analyzing light from distant places in the universe – looking for changes that take place on planets move in front of their stars. But the dip in starlight from KIC 8462852 does not seem to be the normal pattern for a planet.
Tabetha Boyajian, a postdoc at Yale, told the Atlantic: “We’ve never seen anything like this star. It was really weird. We thought it might be bad data or movement on the spacecraft, but everything checked out.”
In 2011 the start was flagged up again by several members of Kepler’s “Planet Hunters” team – a group of ‘citizen scientists’ tasked with analyzing the data from the 150,000 stars Kepler was watching. The analysts tagged the stars as “interesting” and “bizarre” because it was surrounded by a mass of matter in tight formation.
This was consistent with the massive debris that surrounds a young star just as it did with our sun before the planets formed. However this star was not young and the debris must have been deposited around it fairly recently or it would have been clumped together by gravity – or swallowed by the star itself.
Boyajian, Who oversees the Planet Hunters project, recently published a paper looking at all the possible natural explanations for the objects and found all of them wanting except one – that another star had pulled a string of comets close to KIC 8462852. But he said even this would involve an incredibly improbable coincidence.
At this stage, Mr. Reich, the astronomer from Penn State University, along with his colleague Andrew Siemion, the director of SETI ( Search for Extra Terrestrial Intelligence), got involved. Now the possibility the objects were created by intelligent creatures is being taken very seriously by the team. As civilizations become more technologically advanced, they create new and better ways of collecting energy. With the end result being the harnessing of energy directly from their star. If the speculation about a mega-structure being placed around the star system is correct, scientists say it could be a huge set of solar panels placed around the star.
The three astronomers want to point a radio dish at the star to look for wavelengths associated with the technological civilizations. In the first observation could be ready to take place as early as January, with follow-up observations potentially coming even quicker.
“If things go really well, the follow-up could happen sooner,” Wright told the Atlantic. “If we saw something exciting, we’d be asking to go on right away.”
