Radio signal detected for the first time from a planet outside our solar system
- Researchers from the Center for Astrophysics | Harvard & Smithsonian and the University of Oregon reported last week the first direct detection of auroral radio emission from Beta Pictoris b, a gas giant 64 light-years from Earth.
- The radio bursts originate from Electron Cyclotron Maser Instability , an auroral process similar to those on Earth and Jupiter, solving the long-standing challenge of distinguishing exoplanet signals from host star emissions.
- Using distant quasars as reference points to map the sky, astronomers isolated the signal and calculated a magnetic field strength of at least 1,250 gauss—thousands of times stronger than Earth's 0.5 gauss.
- Astrophysicist Suzanne Aigrain emphasized the signals stem from natural phenomena, stating "this is definitely not aliens," while the discovery marks the first direct measurement of an exoplanet's magnetic field.
- The findings, submitted September 15 to arXiv, await formal peer review, though researchers plan to examine 7 other known giant exoplanets across 5 nearby systems using the same detection method.

Radio Waves From Far-Off Planet Appear to Be a First
Astronomers say they've picked up a radio signal from a planet 63 light-years away—but, alas, it's not aliens calling. The bursts appear to be coming from Beta Pictoris b, a massive gas giant about 12 times Jupiter's mass, and point to the existence of an enormous magnetic field driving...

VanguardiaBeta Pictoris b appears to present an aurora caused by a powerful magnetic field.If confirmed, it would be the first field of this type known outside our solar system.
Radio signal detected from exoplanet for the first time
By Jacopo Prisco, CNN (CNN) — Astronomers say they have directly detected the first-ever radio emission from a planet outside the solar system. The signal, however, is evidence of a colossal magnetic field — not intelligent life.“I know radio signals are associated with searches for extraterrestrial intelligence,” said Edo Berger, a professor of astronomy at

Astronomers detect unprecedented radio signal — it's coming from a gigantic planet
Scientists using a vast array of antennas have made a unique discovery coming from out this world.What makes the discovery groundbreaking is that for the first time, the signal Earth is receiving is clear.'No radio detection has previously been unambiguously localized.'Using the 64-dish array called MeerKAT, scientists have been able to capture radio signals coming all the way from a distant gas giant planet called Beta Pictoris b, more than 63 …
