Mysterious signals are coming from deep space

Astronomers have picked up a very unusual repeating signal from a distant galaxy and nobody knows what it is.
Known as a fast radio burst - the signal is a powerful burst of radio waves that, despite lasting mere milliseconds, generates as much energy as the Sun does in an entire day.

While several of these bursts have been picked up over the last few years, this one - which is coming from a source 1.5 billion light years away - is particularly unusual because it appears to be repeating.

It is only the second time a repeating fast radio burst has ever been detected by scientists and as things stand, its exact nature and origins remain a complete mystery.

It has even been suggested that these repeating signals could be evidence of intelligent aliens.

"Knowing that there is another suggests that there could be more out there," said astrophysicist Ingrid Stairs from the University of British Columbia.

"And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them."

LOL.. very large all right.  I believe ET's exist and have powers that may even seem to be magical, but I find it almost impossible to believe ET's had anything to do with this.

It's been discussed in scientific circles that an extraterrestrial civilization could be a billion years older than ours. Consider the progress we've made in science and technology, in the last couple of centuries. The accomplishments of a race with a billion year head start  would very probably be unimaginable to us.

Wow! Thanks for the info!

  I agree with everything you say.  Just try to understand that the object that created this incredible energy release would be the size of a galaxy. Man made??  YIkes!

For example, all objects in our galaxy do (even you), around Sagittarius A*. Well, yes.

It is perfectly possible to orbit a black hole. If the Sun was replaced with an equally massive black hole there would be no change in Earths orbit..... it would soon get awfully dark and cold though.

Sure, it's true that anything can orbit a black hole. But would an object like this have anything orbiting it? (I don't know - I'm not an astrophysicist.) Consider that black holes are likely created at the end of life of the most massive stars - which means stars with the shortest lives, probably measured in barely tens of millions of years. That sort of life span suggests to me they're unlikely to have time to develop anything much of a solar system. Plus, I'm guessing stars like that would have colossal solar winds, meaning they'd quickly disperse any material in the proto-planetary disc. F... [More]

They give only enough to allow us to make up the rest in our minds instead of finding out for ourselves, together. I am very certain normal folk would have found it all out agessss ago if we had local conservatories we could go to from early childhood onwards. Oh mannnn, that would be the best..... imagine that! x

Chances of us reaching a billion years old is very slim.

Agreed. With the state of the world these days aiming for 100 more seems far fetched.
