Astronomers are one step closer to learning whether there is life beyond Earth, following the discovery of an exoplanet that’s able to emit a “coherent” radio signal.
, following the discovery of an exoplanet that’s able to emit a “coherent” radio signal.
On Earth, our magnetic field extends from the molten iron in the planet’s core out into space and protects life from cosmic radiation and charged particles released from the Sun.also have magnetic fields, however, they’re all much stronger than Earth’s. Researchers Sebastian Pineda and Jackie Villadsen discovered the signals with the help of a radio telescope.
Joe Pesce, program director for the National Radio Astronomy Observatory said the discovery would play a crucial role in determining how magnetic fields work on other planets.

Do Earth-like exoplanets have magnetic fields? Far-off radio signal is promising signEarth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly blasted out of the sun. Researchers have now identified a prospective Earth-sized planet in another solar system as a prime candidate for also having a magnetic field—YZ Ceti b, a rocky planet orbiting a star about 12 light-years away from Earth.
