Radio Emissions Detected Outside the Milky Way

Washington, Aug 1 (Prensa Latina) An international team of astronomers identified four powerful radio emissions they said may have being originated out of the Milky Way.

According to the analysis, published by the journal Science, emissions of hertzian waves seem to last a few milliseconds and come from the other side of the Universe apparently.

The experts verified these were not interferences originated in earth, but the phenomenon traveled a long distance to reach the galaxy.

These emissions were detected during one year by exploring relatively small patches of the sky. Scientists also noted that it can be possible to identify other thousands while completing the study.

Astronomers do not know the exact origins of these radio signals, but some theories suggest they are the result of an important cosmological event occurred millions of years ago, as a cataclysm.

Experts believe that the emissions were originated from an extremely catastrophic event because of something that has been destroyed and had never happen again, as a supernova or a gigantic explosion of a magnetar (neutron star fed with a magnetic field very strong).

In 2007, it was first detected a mysterious radio pulse from outside the galaxy and, at that time, experts do not know what it was and discussed the possibility of interference created by the Earth.

Therefore, the team decided to explore the skies with a radio telescope to search for pulsars, spinning neutron stars or remnants of stars that have exploded.
