Impressionanti immagini ingrandite del sole
Nuove immagini del telescopio solare Inouye della National Science Foundation (NSF), il cannocchiale solare più potente del mondo, mostrano alcuni scatti che mostrano immagini che non ci saremmo aspettati.
Si tratta di foto incredibilmente ravvicinate della superficie infuocata e carica di plasma del nostro Sole.
La cromosfera, ossia lo strato intermedio dell’atmosfera della stella, parrebbe, ha detto un osservatore, un tappeto a pelo lungo.
Nella cromosfera si vedono delle ciocche che in realtà le linee di plasma in fiamme note come «spicole».

The surface of our Sun – such hugely wild power & heat!

Secondo Smithsonian Magazine, le spicole eruttano dalla superficie del Sole a circa 60 miglia al secondo e possono estendersi per circa 6.000 miglia.
Happy Friday! A great day for a new look at the Sun. Recently released by the Daniel K. Inouye Solar Telescope (DKIST).

Precedenti immagini ravvicinate avevano mostrato macchie solari sono somiglianti a una porta per l’inferno o all’occhio di Saurone, mentre alcune gocce di plasma fotografate sembrano una croccante barretta di nocciole caramellate.
How is a solar sunspot?
This image, with incredible detail, shows us the true structure of a sunspot and the photosphere around. Wonderful !Image: @NSF’s Inouye Solar Telescope pic.twitter.com/WoGYMtS4Cx

The sharpest image yet of the roiling plasma in a sunspot, taken by the new Inouye Solar Telescope. This scene is a little larger than the Earth (!). https://t.co/M8fJpD9OeJ pic.twitter.com/q8mQPJxQZX

The first images from NSF’s Inouye Solar Telescope – a pattern of turbulent “boiling” plasma that covers the entire Sun. The cell-like structures are each about the size of Texas #space #science #telescope https://t.co/ytprHdEvri pic.twitter.com/rFATkur66M
