Strange radio signals from Earth-like planet: magnetic field discovered

Earth’s magnetic field protects life on the planet, and astronomers have found evidence of a magnetic field on a rocky exoplanet 12 light-years away. Magnetic fields are essential for life on a planet.

The magnetic field shields living things from the sun’s rays, pulls compass needles to the north and causes images known as the northern lights. It is known that other planets in our solar system also have magnetic fields. A research topic was whether similar fields exist on extrasolar planets.

Observations from the VLA radio telescopes in the US provided evidence of a planetary magnetic field around a star just 12 light-years from Earth.

Magnetic field detection on the rocky planet YZ Ceti B is the first discovery from outside the solar system. “This research shows that this particular rocky exoplanet is not only likely to have a magnetic field, but also offers a promising method for finding more,” said study co-author Joe Pesce. said.

Magnetic fields are of particular interest to astronomers, as they are an essential part of making a planet habitable. Without a magnetic field, energetic particles from a star could erode a planet’s atmosphere and strip away the gas cover that could support life.

“The search for potentially habitable or life-supporting worlds in other solar systems depends in part on being able to determine whether rocky, Earth-like exoplanets do indeed have magnetic fields,” Pesce said. he said.

It has been predicted not to be habitableWhen researchers look at YZ Ceti B, they think the planet is not habitable despite its magnetic field. YZ Ceti B is very close to its star and is probably a very hot spot. Also, a year on the planet is so fast that it is equivalent to two days on Earth.

“If it has its own atmosphere, the planet must also have an aurora. This gives us new information about the environment around stars. We call this idea ‘extrasolar space weather’,” says Sebastian Pineda, one of the study’s authors. used the sentences. However, the team isn’t entirely sure if the star aurora comes from AI Ceti b.
