The world’s most powerful radio antenna detects mysterious signals from 19 distant stars


Revealed astronomers who use The most powerful radio antenna In the world about some signals coming from 19 distant stars, and all signals are 165 light-years from Earth, and perhaps four of the signals indicate the presence of hidden planets orbiting these stars.

According to the British newspaper, “Daily Mail”, the team at the University of Queensland, which includes experts from the Dutch National Observatory, used a powerful radio telescope, a low-frequency array (PROMISES) and based in the Netherlands, where astronomers know from observations in the solar system, that the planets emit strong radio waves Its magnetic fields interact with the solar wind.

The team said that this is the first time that they have been able to Astronomy scientists The discovery of radio waves likely from an exoplanet, an important step for radio astronomy.

They can’t tell the size of the suspected planets or whether they are habitable, but these signals are similar to those seen when Jupiter interacts with the solar wind.

The study’s lead author, Dr. Benjamin Pope, said their findings could lead to new techniques in the search for worlds orbiting stars other than our own.

The discovery of radio signals from distant stars opens up radio astronomy as a way to find planets orbiting those stars.

The discoveries with this telescope are only the beginning, although it only has the ability to observe relatively nearby stars, up to 165 light-years away.

design a telescope PROMISES by ASTRON in the Netherlands, but has stations all over Europe, from the UK to Italy working collaboratively to get a single, larger signal.
