Narkevic was using custom software that McLaughlin and her graduate advisor had recently designed to help identify pulsars. Two of his professors, Duncan Lorimer and Maura McLaughlin, had tasked him with sifting through 5-year-old data from the Parkes radio telescope in Australia. In 2007, David Narkevic, then a physics undergrad student at West Virginia University, stumbled on something unusual when combing through archival data. And even if we don’t find them, we’ll learn a lot about the nature of the universe in the process. If we want to party with all of the cool extraterrestrial biological entities (EBENs) and prove once and for all if aliens exist, we might have to seek them out ourselves.

As time passes, pulsars slow down, and their pulses get fainter with age until they finally stop producing radio signals.Īnother possible theory is that the celestial object could be an ultra-long period magnetaror a rare kind of neutron star with powerful magnetic fields which produces powerful bursts of energy. The most likely reason is the presence of pulsars or neutron stars that flashes and rotates like a lighthouse that emits energetic beams as they move toward and away from Earth. The astrophysicist called the pulsar "LGM 1" or "Little Green Men 1" before further observations ruled out this possibility. It happened when the first pulsar was detected. Hurley-Walker explained that it can be tempting to assume that the source of the signal is a form of extraterrestrial intelligence.

The discovery of the signal has left the scientists baffled since it has been occurring at intervals and for a time initially thought impossible. The radio wave pulses, GPMJ1839-10, are assumed to be coming from a source 15,000 light years away from Earth. Even more alarming is that this strange radio signal went undetected for over three decades without assurance of what it could be. This time, the interstellar waves arrive in the energy of varying brightness levels and occur every 20 minutes, sometimes lasting for 5-minute intervals.īy studying the records at the Very Large Array in New Mexico, a facility that maintains the longest-running data archive, the researchers found out that the pulse of the source was first detected in 1988. In just a short amount of time, they were able to discover a new source in a different region in space. The team used the Murchison Widefield Array radio telescope in Western Australia to scan the Milky Way galaxy every three nights for several months. The astronomers tried to look again, hoping to find another source of long-term radio signals. The source no longer produced radio waves when the data were analyzed after two years. In 2018, Curtin University astronomers from the International Centre for Radio Astronomy Research (ICRAR) gathered data revealing the first detected magnetar spinning slower than usual with similar signals sent every 18 minutes. The Earth has been intermittently hit by a regular burst of radio signals from an unknown source in the universe.
