Researchers have discovered that black holes can pump and release huge amounts of energy through magnetic fields and magnetized accretion disks, which could change our understanding of galaxy formation and the evolution of the universe.
The black hole of our Milky Way as seen in polarized light. Astronomers have for the first time been able to measure polarity, a hallmark of magnetic fields, so close to the rim of Sagittarius A*. The lines added to the image indicate the direction of polarization, which is related to the magnetic field around the shadow of the black hole. Credit: EHT Collaboration

For the first time, a phenomenon that astronomers had long hoped to photograph directly has been captured by the NASA/ESA/CSA James Webb Space Telescope's Near Infrared Camera (NIRCam). In this spectacular image of the Serpent Nebula, the discovery is in the northern region of the Young Zone And this star-forming relative NASA, ESA, CSA

Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT

The magnetic field and electric currents in and around the Earth produce complex forces that have a huge impact on our day-to-day lives. One can imagine the field as a giant bubble, protecting us from space radiation and charged particles with which solar winds bombard the earth. Credit: ESA/ATG medialab
