    It ain't aliens, but nobody knows what it might be.
    Whatever they are, something very powerful is emitting them. Radiation follows the inverse square law and these bursts have the same level of energy as a cellphone signal on the Moon traveling towards the Earth when they get here. Which means they must have been emitted with a whopping amount of energy by their source.

    Pulsar wobbling as it rotates, most likely.

    okay I just HAD TO DO THIS! When will I ever get another chance to put a Marvin Gaye song in a techforge thread? :shrug: Science brought this on itself you know!

    Having just learnt the inverse square and other inverse power laws as part of my OU compsci course, I'm half tempted to find out what the received signal power was and work it back...

    I've seen articles that often speculate on an artificial origin of signals received from space. Without fail they're devoid of logic.

    No, aliens aren't sending us a signal from 50 million light years away. Humanity, let alone technological civilization, wouldn't have existed on Earth when the message was sent, so the aliens would've really been rolling the dice to send a message this way.

    No, we're not going to intercept alien radio signals. One, intelligent aliens--like intelligent humans--would transmit signals in a highly directional fashion, so no off that axis would receive much/any signal. Two, there's no point sending radio energy in all directions when you only need it to go in one, especially given how much power it takes to transmit a radio signal across interstellar space. Three, they--like us--wouldn't use more transmission power than they need; there's no point wasting energy to transmit a signal a million light years when it only has to go a dozen.

    That this new signal repeats so steadily is indicative of some regularly occurring phenomenon. Some energetic system is rotating on a 16 day period and once in each cycle, it's oriented in a way that transmits more power toward us.
