Not claiming it’s aliens but it is certainly a puzzle.
Astronomers: “The brightness of the object also varies dramatically, by a factor of 100, and the signal switches on and off apparently at random. We’ve never seen anything like it.” :
“Strange radio waves emerge from direction of the galactic centre”? Yes, it sounds like the opening of a trailer for a sci-fi film. But it is actually a media release from last week from the University of Sydney in Australia:
Astronomers have discovered unusual signals coming from the direction of the Milky Way’s centre. The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object.
“The strangest property of this new signal is that it is has a very high polarisation. This means its light oscillates in only one direction, but that direction rotates with time,” said Ziteng Wang, lead author of the new study and a PhD student in the School of Physics at the University of Sydney.

They are sure it is not a pulsar but not of much else. This is how it appears:

Could it be a signal of some type from an intelligent source? If so, there should be patterns but not ones governed wholly by natural forces.

We will soon be in a better position to find out because the Square Kilometer Array (SKA) radio telescope will be commissioned within the decade.

Quantum physicist speculates: Aliens may communicate by starlight. Terry Rudolph of Imperial College, London, argues that they may have evolved so as to take advantage of quantum mechanics via photonics more easily than we can. Photonics is a form of communication that takes advantage of the fact that light moves faster than electricity. It pays to know about photonics anyway.
