Astronomers Detect Radio Emission From Exoplanet, Urge Caution
Astronomers have detected repeating radio signals that seem to come from a planet called Beta Pictoris b.
The planet is outside our solar system and is about 63 light-years away.
It is a giant planet with about 12 times Jupiter’s mass.
Researchers think its strong magnetic field helps create the signals.
The process may also involve auroras, like the northern lights on Earth.
The planet’s magnetic field is estimated to be at least 200 times stronger than Jupiter’s.
The scientists say this is not a sign of intelligent life.
They hope radio observations can help us learn more about planets beyond our solar system.
Researchers reported repeating radio bursts apparently coming from Beta Pictoris b, an exoplanet about 63 light-years from Earth.
The gas giant is about 12 times the mass of Jupiter and orbits a young star with two other planets.
The team attributes the radio emission to processes linked to the planet’s magnetic field and auroras.
Coauthor Edo Berger said the planet’s magnetic field is at least 200 times stronger than Jupiter’s.
Researchers stressed that the signal is evidence of a strong magnetic field, not intelligent life.
