Strange signals from galaxy center
A series of anomalous radiowave bursts, dubbed GCRTJ1745-3009, has been detected coming from the direction of our galaxy’s center (26,000 light-years away). "The most spectacular aspect of this is that five bursts occurred at regular intervals of about an hour and a quarter [77 minutes]," said Scott Hyman of Sweet Briar College, Virginia. "They were at a constant intensity … and each burst had basically the same time profile." Each burst lasted about ten minutes. Since the source is of an unknown type and the bursts are highly unusual, some believe that the origin of the radiowaves may be intelligent. Hyman’s response: "There’s no reason to expect anything but a natural cause. There are so many classes of objects we don’t know about out there."
