Earth first received a signal from outside the solar system
New Delhi: For the first time, astronomers have captured a radio signal indicating a hidden planet in a crucial discovery. These signals are captured by the low-frequency array (LOFAR) of the Netherlands' most powerful radio antenna in the world.
The new technique of finding hidden planets can also provide information about life outside the solar system, which has been the biggest question for astronomy so far. Are we alone or is there anyone else. Dr. of the University of Queensland. The discovery was made by Benjamin Pope and his associates at the Dutch National Observatory Astron. Astronomers are searching for planets using LOFAR.
Astronomers have discovered 14 distant red dwarfs, four of which are known to be orbiting planets. We have long known that the magnetic fields of our solar system planets emit powerful radio waves when they are exposed to the solar wind, but we have not yet been able to capture the radio signals outside our planetary system.
Previously, every astronomer could detect the nearest star only by radio current coming at a constant rate. Radio astronomers could now see the old plain old star when they observed the red dwarf stars. This star is much smaller than the sun.
According to a study published in Nature Astronomy, the team believes that these signals come from the magnetic attachment of the stars and are orbiting invisible planets around them. A similar harmony is observed between Jupiter and its moon. Dr. of Astron Leiden University. Joseph Collingam said that our Earth also has an aura, it is more prevalent mainly at the North and South Poles. Here the Earth's magnetic field is more exposed to the solar wind, so more radio waves are emitted.
