Webb Telescope Reveals Record-Breaking Radio Burst Originated in a Tiny, Young Galaxy

Astronomers have identified the host galaxy of FRB 20240304B, the most distant fast radio burst ever detected. The signal originated when the universe was just 3 billion years old, traveling through 80% of cosmic history. Detected by the MeerKAT telescope in March 2024 and confirmed by the James Webb Space Telescope (JWST), the burst emerged from a surprisingly small, young dwarf galaxy. This finding challenges previous assumptions that FRBs originate from massive, older galaxies, instead supporting theories that they are produced by young magnetars.

JWST locates record-breaking fast radio burst in tiny, ancient galaxy

Astronomers identified the most distant fast radio burst (FRB) ever recorded, FRB 20240304B, originating over 10 billion light-years away. Detected by South Africa’s MeerKAT telescope in March 2024, the signal’s host galaxy was confirmed by the James Webb Space Telescope (JWST) as a small, metal-poor dwarf galaxy actively forming stars. Published in *Science* on October 8, the study places the event just 3 billion years after the Big Bang, more than doubling the previous distance record. The findings suggest FRBs may be common in the early universe and support theories linking them to young magnetars rather than older neutron star mergers.

JWST Confirms Record-Breaking Radio Burst from Universe’s First 3 Billion Years

Astronomers have identified the most distant fast radio burst (FRB) ever recorded, designated FRB 20240304B. Detected by South Africa’s MeerKAT telescope in March 2024, the signal originated when the universe was only 3 billion years old, traveling for over 10 billion years to reach Earth. The James Webb Space Telescope (JWST) confirmed the host galaxy’s redshift at 2.148, placing it more than twice as far as the previous record holder. The host is a small, low-mass dwarf galaxy with intense star formation and low metallicity, challenging previous assumptions that FRBs originate in massive, evolved galaxies. This discovery suggests FRBs may have been common in the early universe and provides a new method for mapping invisible intergalactic matter.

Webb Telescope Identifies Tiny, Ancient Galaxy as Source of Record-Breaking Fast Radio Burst

Astronomers have identified the host galaxy of the most distant fast radio burst (FRB) ever detected, designated FRB 20240304B. Using the James Webb Space Telescope (JWST), researchers confirmed the burst originated just 3 billion years after the Big Bang, during the peak of cosmic star formation. The host is a surprisingly small dwarf galaxy, challenging previous assumptions that FRBs occur in massive, older galaxies. This discovery supports the theory that FRBs are generated by magnetars from recent supernovae rather than neutron star mergers, and allows scientists to map invisible matter across 80% of cosmic history.

Webb Telescope Identifies Host Galaxy of Record-Breaking 10-Billion-Year-Old Radio Burst

Astronomers have identified the host galaxy of FRB 20240304B, the most distant fast radio burst ever detected. The signal originated 10.6 billion years ago, when the universe was only 3 billion years old. The burst was detected by the MeerKAT telescope in South Africa and its host galaxy was confirmed by the James Webb Space Telescope. The host is a surprisingly small, young dwarf galaxy actively forming stars, which supports theories that fast radio bursts are generated by young magnetars rather than older neutron star mergers.

Record-Breaking Radio Burst Detected from Galaxy Formed in Early Universe

Astronomers have identified the most distant fast radio burst (FRB) ever recorded, originating from a galaxy that existed when the universe was only 3 billion years old. Detected via the MeerKAT telescope in South Africa and confirmed by the James Webb Space Telescope, this burst traveled for over 10 billion years, covering approximately 80% of cosmic history. The source is a young, metal-poor galaxy with rapid star formation, challenging existing theories about FRB origins. This discovery suggests FRBs were common in the early universe and provides a new method for mapping unseen matter across vast cosmic distances.

Astronomers Confirm First Direct Radio Signal from Exoplanet Beta Pictoris b

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.

MeerKAT Telescope Confirms First Direct Radio Detection from Exoplanet Beta Pictoris b

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.

MeerKAT Telescope Confirms First Direct Radio Emissions from Exoplanet Beta Pictoris b

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.

MeerKAT Detects First Direct Radio Emission from Exoplanet Beta Pictoris b

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.

Harvard Team Pinpoints Radio Emissions from Exoplanet Beta Pictoris b

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.

Astronomers Pin Radio Bursts to Exoplanet Beta Pictoris b, Marking First Direct Detection

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.

First Direct Radio Detection from Exoplanet Beta Pictoris b Reveals Massive Magnetic Field

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.
