Astronomers report a rare tidal disruption event AT2018hyz producing a narrow, ultra-fast jet from a supermassive black hole 665 million light-years away. The jet is now 50x brighter than when first detected, with total energy up to 5e55 ergs and a predicted peak around 2027, challenging typical TDE models with a long-lived jet. Future observations, including with the SKA, will help uncover more such events.
Astronomers report an ultra-powerful jet from AT2018hyz, a tidal disruption event around a supermassive black hole about 665 million light-years away. Nicknamed “Jetty McJetface,” the jet’s energy output is estimated up to 5×10^55 ergs—between a trillion and 100 trillion times the Death Star’s fictional energy—and it is currently about 50 times more luminous than at first detection in 2018. Models suggest the peak brightness will occur in 2027 as the jet evolves. Jets from TDEs are rare (roughly 1% of cases), and future radio surveys like the SKA could find more such events.
A jet from the supermassive black hole AT2018hyz—nicknamed Jetty McJetface—has brightened over four years to become one of the universe’s most energetic events. The radio emission is now at least a trillion times more energetic than the Death Star and is predicted to peak around 2027, as the star‑shredding tidal disruption powers an increasingly powerful jet that is likely not aimed at Earth.
Using the Event Horizon Telescope’s VLBI observations of M87*, researchers traced the base of the galaxy’s 3,000‑light‑year jet to a region near the black hole’s shadow, linking jet launching to the accretion flow around the supermassive black hole (about 6.5 billion suns) and connecting theory to observation. The finding, based on 2021 data and building on the 2019 image of M87*, was published in Astronomy & Astrophysics.
Astronomers using the Event Horizon Telescope's VLBI observations linked the glowing ring around the supermassive black hole M87* to the base of its 3,000‑light‑year jet, pinpointing where jets originate and helping to illuminate how these powerful outflows are launched from black holes; the findings were published in Astronomy & Astrophysics.
A new image captured by telescopes shows interstellar comet 3I/ATLAS emitting a jet of ice and dust towards the sun, a typical behavior as it warms up, with the jet possibly extending over 6,200 miles, composed mainly of carbon dioxide and dust particles.
New images of interstellar comet 3I/ATLAS reveal a large jet of gas and dust pointing toward the sun, consistent with typical comet behavior, supporting its natural origin rather than alien technology. The comet, the largest and possibly oldest interstellar object ever observed, is approaching perihelion and will be visible again in mid-November for further study.
Scientists used the James Webb Space Telescope to capture the clearest image yet of the powerful plasma jet emanating from the supermassive black hole in galaxy M87, revealing detailed features of the jet and advancing understanding of black hole physics.
A detailed radio image of the blazar OJ 287 reveals a severely kinked jet, providing strong evidence that it hosts the most extreme binary black hole system known, with gravitational interactions causing the jet's reorientation and offering insights into merging supermassive black holes and gravitational waves.
NASA's Chandra X-ray Observatory has detected a surprisingly powerful black hole jet from about 11.6 billion light-years away, during the universe's 'cosmic noon' when galaxy and black hole growth was at its peak. The study identified two black holes with jets over 300,000 light-years long, moving at nearly the speed of light, with their brightness influenced by relativistic effects and viewing angles. This discovery enhances understanding of black hole activity in the early universe.
Astronomers using VLBI observations detected a superluminal relativistic jet in the radio-quiet active galaxy Markarian 110, revealing intermittent jet activity and significant spectral evolution, which provides insights into jet formation mechanisms in AGNs.
Astronomers have discovered the largest black hole jet ever observed, stretching about 200,000 light-years, in a distant quasar from when the universe was less than 1.2 billion years old, revealing insights into early galaxy evolution and black hole activity using advanced radio and infrared telescopes.
A damaged jet is surprisingly set to be used in Arizona, raising questions about its readiness and safety for operation.
The United Kingdom's Joint European Torus (JET) has set a new world record for nuclear fusion energy output, generating 69.26 megajoules of energy from just 0.21 milligrams of fuel, equivalent to the energy from 2 kilograms of coal. This breakthrough showcases the potential of nuclear fusion technology, with JET serving as a pathfinder for future prototypes like ITER and DEMO. While commercial fusion power stations are still years away, these advancements demonstrate the progress and multiple paths toward achieving this goal.
The Joint European Torus (JET) in England has set a new record for the most energy created in a single fusion reaction, marking a significant milestone in nuclear fusion research. Despite nearing the end of its four-decade-long life, JET sustained high fusion power for 5 seconds and produced 69 megajoules of energy using a minuscule amount of fuel. While JET's achievement is noteworthy, it did not surpass the record for energy yield, which was achieved by the National Ignition Facility (NIF) in 2022. Nonetheless, JET's success underscores the progress in fusion energy research and its potential for future commercial applications.
