There were detected some unusual radio waves which were immediately linked with the existence of extraterrestrial life. These intense but extremely brief sounds coming from cosmos became one of the scientists’ first interests. Researchers argued that they did not yet uncover what exactly causes these powerful pulses. The speculations are that distant extraterrestrial populations are sending us signs to prove their existence or this could be a mean of communication for them.
- The unusual radio waves detected triggered the curiosity of astronomers.
- They have considered this as a sign coming from aliens.
Scientists were triggered by these radio pulses, developing a study on radio astronomy. Currently, a team of researchers has uncovered the most powerful and brightest unusual radio wave. This was called FRB 150807 and was registered to last for about half a millisecond. Specialists have related this time span with the amount of time a human needs to blink.
The study was recently published in the Science magazine. Researchers have struggled to identify which is the source of this radio wave pulse. This researcher was conducted after another breakthrough which recorded others unusual radio waves which were followed by gamma rays effusions which representing electromagnetic radiation.
Nevertheless, although those radio waves from the latest study recorded a high intensity, specialists were not yet able to track down the source of this emission. Astronomers are of the opinion that the bright rays were categorized as flashes of light generated in the atmosphere of particular stars situated in the Milky Way. This process was compared to solar flares.
Other experts have claimed that these radio waves are caused by outer space collisions. For example, a neutron star is clashing with a black hole situated in a faraway galaxy. The first powerful radio wave which received the name of Lorimer burst was revealed by radio astronomers who were using the Parkes telescope. They were looking for radio bursts emitted by neutron stars known as pulsars.
The Lorimer burst was categorized as a total mystery until there were identified others unusual radio waves across the globe, captured by other telescopes like the 100-metre Greenbank dish in the US and the Arecibo radio telescope in Puerto Rico. Unfortunately, scientists did not make enough progress regarding the meaning, purpose or source of these strange, powerful pulses.
Researchers were not able to gather much information about these events due to the limited resolution of the telescopes and the short duration of every radio burst.
