FREE! The Event Horizon Telescope (EHT) just made a MAJOR Discovery
about Black Holes. Chat with Heino Falcke, author of LIGHT IN THE
DARKNESS, about what it all means. Light is an oscillating
electromagnetic wave. If the waves have a preferred direction of
oscillation, they are polarized. In space, moving hot gas, or
‘plasma’, threaded by a magnetic field emits polarized light. The
polarized light rays that manage to escape the pull of the black
hole travel to a distant camera. The intensity of those light rays
and their direction is what we observe with the Event Horizon
Telescope. https://licht-im-dunkeln.de/en/home/ GET THE

Magnetic fields around black holes can launch powerful plasma jets
with almost speed of light. They force electrons to gyrate and emit
radio waves. This forces the light to oscillate perpendicular to
the field lines. On 24 March 2021 the EHT collaboration revealed a
breakthrough discovery: the Event Horizon Telescope has imaged
polarized light close to the shadow of M87* for the very first
time. Using this knowledge, we can map out the magnetic fields that
surround the black hole, and connect them to the powerful jet of
plasma it ejects. The Event Horizon Telescope (EHT) is an
international collaboration that captured the first image of a
black hole by creating a virtual Earth-sized telescope. To learn
