The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has successfully detected the faint radio glow of neutral hydrogen from the early universe using only its own data. This milestone, published in The Astrophysical Journal, validates a cost-effective method to map cosmic expansion and investigate dark energy without relying on expensive galaxy surveys.
Researchers from the Center for Astrophysics | Harvard & Smithsonian and the University of Oregon have reported the first direct detection of radio emission from an exoplanet, Beta Pictoris b. Located approximately 63 to 64 light-years from Earth, this gas giant exhibits auroral radio bursts similar to those seen on Earth and Jupiter. The discovery, which was submitted to arXiv on September 15, 2026, indicates a magnetic field strength of at least 1,250 gauss, significantly stronger than Earth's 0.5 gauss. While the signal is not evidence of intelligent life, it provides the first direct measurement of an exoplanet's magnetic field and offers new insights into planetary atmospheres and habitability.
Astronomers have confirmed the first direct radio signal detection from an exoplanet, Beta Pictoris b. Using South Africa’s MeerKAT array, researchers identified auroral emissions indicating a magnetic field over 1,000 times stronger than Earth’s. This discovery provides a new method to measure planetary magnetism and assess habitability, distinct from signals attributed to intelligent life.
Astronomers have detected the first unambiguous radio emission from an exoplanet, Beta Pictoris b, located 63 light-years away. The signal, captured by South Africa's MeerKAT telescope, indicates a massive magnetic field and auroral activity, marking a milestone in directly characterizing planetary magnetism outside our solar system.
An international team using South Africa’s MeerKAT radio telescope array has detected variable radio bursts originating directly from Beta Pictoris b, a gas giant located 63 light-years from Earth. This marks the first confirmed instance of radio signals attributed to a single exoplanet rather than its entire star system. The discovery, which is not evidence of extraterrestrial life, allows scientists to study the magnetic fields of Jupiter-like planets, a factor critical for protecting atmospheres and assessing habitability.
Astronomers using the MeerKAT radio telescope in South Africa have detected the first unambiguous radio signal originating from an exoplanet, Beta Pictoris b. Located 205 light-years away, this young gas giant exhibits auroral activity driven by a magnetic field estimated at over 1,000 gauss, thousands of times stronger than Earth's. This discovery marks a milestone in exoplanetology by allowing direct characterization of planetary magnetism without relying on host star signals.
Astronomers from Harvard and the University of Oregon have detected the first unambiguous radio signal originating from an exoplanet, Beta Pictoris b. Using South Africa's MeerKAT telescope, the team identified auroral bursts that allow for the first direct measurement of an exoplanet's magnetic field strength, confirming theoretical models for young, massive gas giants.
Researchers from Harvard and the University of Oregon have detected radio signals directly from the exoplanet Beta Pictoris b, marking the first time such emissions have been localized to a planet outside our solar system. The signals, captured by the MeerKAT telescope in South Africa, are attributed to natural magnetic activity rather than extraterrestrial life. This discovery allows scientists to measure the planet's magnetic field strength, which is over 300 times stronger than Jupiter's, and confirms the planet's young, massive nature.
A team from Harvard and the University of Oregon has detected radio signals directly from the exoplanet Beta Pictoris b, marking the first time such emissions have been unequivocally linked to a planet outside the solar system. Using the MeerKAT radio telescope in South Africa, researchers identified bursts caused by auroral activity rather than extraterrestrial life. The discovery also yielded the first direct measurement of an exoplanet’s magnetic field, which is approximately 291 times stronger than Jupiter’s.
Astronomers have detected the first direct radio signal from an exoplanet, Beta Pictoris b, using the MeerKAT telescope in South Africa. The signal, attributed to natural auroral activity rather than extraterrestrial life, reveals a magnetic field over 300 times stronger than Jupiter’s. This breakthrough allows for the first direct measurement of an exoplanet’s magnetic field, confirming theoretical predictions for young, massive gas giants.
Astronomers have detected the first unambiguous radio signals originating from an exoplanet, Beta Pictoris b, located 63 light-years away. Using South Africa’s MeerKAT radio telescope, researchers identified short, circularly polarized bursts caused by auroral activity. This discovery confirms the planet possesses a magnetic field thousands of times stronger than Earth’s, marking a milestone in characterizing distant worlds without relying on starlight.
Astronomers have detected the first unambiguous radio signals from an exoplanet, Beta Pictoris b, using South Africa’s MeerKAT telescope. The signals, likely caused by auroral activity, reveal a magnetic field roughly 1,250 gauss, thousands of times stronger than Earth’s. This breakthrough allows scientists to study planetary magnetic fields and atmospheric interactions directly, moving beyond simple detection to characterize distant worlds.
Astronomers have detected the first confirmed radio signals originating directly from an exoplanet, Beta Pictoris b. Using South Africa's MeerKAT telescope, researchers identified auroral emissions that reveal the planet's magnetic field is thousands of times stronger than Earth's. This discovery marks a milestone in characterizing distant worlds and assessing their potential to support life.
Astronomers have achieved a historic first by detecting radio signals directly from an exoplanet, Beta Pictoris b, rather than its host star. Using the MeerKAT radio telescope array in South Africa, researchers observed rapid, circularly polarized bursts between 0.85 and 3.5 GHz during four observation sessions in 2025 and 2026. These signals, attributed to auroral activity driven by an Electron Cyclotron Maser Instability, indicate the planet possesses a magnetic field thousands of times stronger than Earth's. This discovery provides the first direct measurement of an exoplanet's magnetic field strength, confirming previous dynamo-scaling predictions for this massive, rapidly rotating giant planet located 63.4 light-years away.
A new study published in Nature uses an AI model called Kine to convert 116 sparse radio observations of blazar 3C 345, taken between 1995 and 2022, into a continuous, high-resolution video. This reconstruction reveals apparent superluminal motion and challenges traditional interpretations of jet dynamics.
