Edited SDO PR image of small prominences on the sun. Color/processing variant.

Original caption: NASA's Solar Dynamics Observatory (SDO) observes two relatively small prominences above the Sun's surface twisted and streamed charged particles over a 20-hour period (July 30-31, 2018), shown here in a wavelength of extreme ultraviolet light. Prominences are large, bright features anchored to the Sun's photosphere but extending outward into its hot outer atmosphere, called the corona. Scientists are still researching how and why prominences are formed.

Today, the solstice is at 17:11 Universal Time, the Sun reaching the southernmost declination in its yearly journey through planet Earth's sky. The December solstice marks the astronomical beginning of winter in the northern hemisphere and summer in the south. To celebrate, explore this creative visualization of the Sun from visible to extreme ultraviolet wavelengths, using image data from the orbiting Solar Dynamics Observatory (SDO). Against a base image made at a visible wavelengths, the wedge-shaped segments show the solar disk at increasingly shorter ultraviolet and extreme ultraviolet wavelengths. Shown in false-color and rotating in a clockwise direction, the filters decrease in wavelength from 170 nanometers (in pink) through 9.4 nanometers (green). At shorter wavelengths, the altitude and temperature of the regions revealed in the solar atmosphere tend to increase. Bright at visible wavelengths, the solar photosphere looks darker in the ultraviolet, but sunspots glow and bright plasma traces looping magnetic fields. Watch the filters sweep around the solar disk in this animation of SDO's multiwavelength view of the Sun.

SDO is a 3-axis stabilized spacecraft, with two solar arrays, and two high-gain antennas. The spacecraft includes three instruments: the Extreme Ultraviolet Variability Experiment (EVE) built in partnership with the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics (LASP), the Helioseismic and Magnetic Imager (HMI) built in partnership with Stanford University, and the Atmospheric Imaging Assembly (AIA) built in partnership with the Lockheed Martin Solar & Astrophysics Laboratory.
SDO (Solar Dynamics Observatory):
I am from an era when the children eagerly gathered around the
television, with the adults lurking in the background trying to
pretend they weren't just as excited, every time NASA launched
ANYTHING. I remember we'd plan finger food dinners so we could be in
the living room and not miss anything, or beg to skip school. When
Jules Bergman started talking, I would shush any of the younger
siblings who were squirming or causing trouble in the background.
You knew that the world was watching. That everyone you knew was glued
to their televisions or their neighbor's television, just like we were
to ours. I come from a large family, and the house wasn't big enough,
so we would scatter pillows on the floor and crowd in around the TV. I
can't describe what it felt like. The closest thing I can think of now
is the Olympics, but watching NASA rockets take off was ... bigger. It
was universal, it felt as big as the whole sky, it felt as if we ALL
were out there with the astronauts, and at the same time as if they
lived a life so different from anything we could ever possibly
imagine.
For decades now I have missed that. Missed watching the launches on
TV, missed the communal sense that HERE, *this* was important, this
was changing the world, this would make a difference, this was opening
a door to something very real and unimaginable. Instead of "Here be
Dragons" it was "Here be Miracles," with the sense that all of us
watching somehow joined in the miracle, were touched by it.
Now, you can relive those days, those dreams, that sense of community
and the world watching together. NASA is doing so much with social
media, I can't begin to describe it all here. But for a start, a very
faint start, you can watch the launch of the new satellite for
observing our Sun in Second Life on Astronomy 2009 tomorrow morning,
if the launch isn't rescheduled again. The weather has been funky this
week, as I'm sure you've noticed. :) If you are not a Second Life
afficionado, you can join on the the Twitter discussions or host a
launch party. Or at the very least you can watch the conversation in
Twitter with tools like TwitterFall. At least, you can, if you aren't
in another meeting, like I am supposed to be.
Here is the SL announcement from tonight about tomorrow.
SDO is enclosed in its Atlas V payload fairing and ready for transport to the pad.

Edited SDO image of of an active area on the sun.
Image source: photojournal.jpl.nasa.gov/catalog/PIA22645
Original caption: NASA's Solar Dynamics Observatory (SDO) zoomed in to watch close-up the dynamics of this single active region on the sun over a two-day period (July 14-16, 2018). The loops SDO observed in extreme ultraviolet light are illuminated by charged particles spinning along the magnetic field lines above an active region. Active regions are magnetically intense areas that are pushed up to the surface of the sun from below. These regions are often the sources of large eruptions that cause solar storms, though no large eruptions seem to have occurred during this period. To give a sense of scale, these loops are rising up many times the diameter of Earth.
