Churning Filament
A developing filament near the edge of the sun churned and twisted as the rotating sun brought it into clearer view over a day (Nov. 16-17, 2017). Filaments are cooler and often unstable clouds of particles floating above the sun's surface, which are tethered by magnetic forces. In extreme ultraviolet light, they appear darker than the sun's surface. The bright area to the right of the filament is an active region. The loop that appears behind the filament in the middle of the clip is made of charged particles tracing magnetic field lines.

From hot to hottest
This sequence of images shows the sun from its surface to its upper atmosphere all taken at about the same time (Oct. 27, 2017). The first shows the surface of the sun in filtered white light; the other seven images were taken in different wavelengths of extreme ultraviolet light. Note that each wavelength reveals somewhat different features.
They are shown in order of temperature from the first one at 6,000 degree C. surface out to about 10 million degrees C. in the upper atmosphere. Yes, the sun's outer atmosphere is much, much hotter than the surface. Scientists are getting closer to solving the processes that generate this phenomenon.

The Sun: Two Significant Solar Flares | NASA SDO
On Sept. 6, 2017, the Sun released the most powerful solar flare recorded since 2008. Our nearest star has been lively all week, emitting three flares—two of which were "X-class," the most intense kind. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured this image of the largest flare.

The Sun: Sprawling Coronal Hole | NASA SDO
A large coronal hole stands out as the most obvious feature on the sun this week (Oct. 12-13, 2017). The dark structure, shaped kind of like the Pi symbol, spreads across much of the top of the sun. Though one cannot tell from this video clip in false-color extreme ultraviolet light, it is spewing high-speed solar wind particles into space and has been doing this all week. It is likely that these charged particles have been interacting with Earth's atmosphere and generating many aurora displays in regions near the poles the past several days.

The Sun: Dynamic Duo | NASA SDO
This close-up video clip shows a pair of active regions (the brighter areas) move and change as they rotate with the sun over just a 17-hour period (Oct. 4-5, 2017). They were observed in a wavelength of extreme ultraviolet light that reveals plasma heated to over a million degrees. The arches above the regions consist of charge particles spinning along and revealing magnetic field lines. Each one shows a few minor bursts of material none of them were serious.

The Sun: Trio of Tempests | NASA SDO
Three distinct active regions with towering arches above them rotated into view over a three-day period (Sept. 24-26, 2017). In extreme ultraviolet light, charged particles that are spinning along the ever-changing magnetic field lines above the active regions make the lines visible. To give some sense of scale, the largest arches rose up many times the size of Earth.
