Astronomers said it marked the first time this type of radio signal has been detected at such a large distance. 'It’s the equivalent to a look-back in time of 8.8 billion years.'

"There are not many things in the universe that emit strictly periodic signals," Daniele Michilli, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research, said at the time. "Examples that we know of in our own galaxy are, which rotate and produce a beamed emission similar to a lighthouse. And we think this new signal could be a magnetar or pulsar on steroids.

"It’s the equivalent to a look-back in time of 8.8 billion years," Arnab Chakraborty, a Post-Doctoral Researcher at McGill University, said in a statement.
