MYSTERIOUS SIGNALS FROM SPACE BEING TRACKED
NASA traces source of fast radio bursts sending signals to Earth
Don’t panic, but mysterious sources have been sending radio signals to Earth for years. Now, scientists have tracked down some of their origins — and they were surprised by what they found.
And no, it’s still not aliens.
Using NASA’s Hubble Space Telescope, astronomers have traced the locations of five deep space signals known as fast radio bursts (FRBs). In a thousandth of a second, these powerful blasts generate as much energy as the sun does in an entire year.
Around 1,000 FRBs have been detected since the first one was discovered in 2001, but they are notoriously difficult to track because they disappear in an instant and without a trace. Only 15 of them have been tracked to specific galaxies.
Scientists are interested in tracking where these intense pulses are coming from so they can determine what kind of cosmic events trigger them.
