There’s a Magnetic Hole in the Sun

@...@Imaged by NASA*s© Solar Dynamics Observatory through filters that are sensitive to extreme ultraviolet light, this huge dark spot in the center of the sun*s disk is a low density region of plasma in the sun*s corona//

@...@The solar corona is a magnetically~dominated region, populated with **open** and **closed** magnetic field lines, © that protrude from the sun*s interior and into the corona, along which the super~heated plasma is guided// The bright regions in this image are locations of closed field lines, known as coronal loops// Dense plasma is trapped in these elegant loops, being heated, generating intense radiation//
