A distant, Earth-sized planet emitting a radio signal which could point to it having a similar magnetic field to ours has been discovered .
Using a radio telescope, the scientists found exoplanet YZ Ceti b - which is around 70.5 trillion miles away from Earth - to be giving out a repetitive radio signal.
Do Earth-like exoplanets have magnetic fields?
Researchers Sebastian Pineda and Jackie Villadsen observed a repeating radio signal emanating from the star YZ Ceti using the Karl G. Jansky Very Large Array, a radio telescope operated by the U.S. National Science Foundation's National Radio Astronomy Observatory.
A planet's magnetic field can prevent that planet's atmosphere from being worn away over time by particles spewed from its star, explains Pineda, an astrophysicist at the University of Colorado.
50 years ago, Pioneer 11 set sail for the outer solar system | Astronomy.com
Pioneer 11 is just one of five spacecraft currently on a trajectory that will take it out of the solar system.
However, Pioneer 11 was never meant for longevity. This quarter-ton, car-sized probe, brimming with 12 scientific instruments and powered by four plutonium generators, was a reserve player on NASA’s bench with limited candidacy for greatness.
