Sun-gazing

Dopplergrams from the NASA's space telescope IRIS (Interface Region Imaging Spectrograph) revealing detailed evidence of "twist" between the sun's surface and outer atmosphere. These phenomena may play a role in driving the temperature difference between the sun's surface (~6000 K) and the sun's outer atmosphere (millions of degrees). The reason for this enormous temperature gradient is not fully understood (a puzzle known as the "coronal heating problem"). Image: De Pontieu et al., Science 2014

By Galileo’s careful hand, sunspot details are exquisite,

Through eye of forehead, eye of mind beholds what body can not visit.

If only he could see the sights now rendered from Earth’s outer space,

Ultraviolet sunscapes – Oh, to see his raptured face!

High above Earth’s atmosphere, IRIS probes the edges of our star,

A telescope in orbit, through its lenses, we see far.

Six thousand Kelvin screams the surface, roiling plasma, like hellish seas,

Hotter still, the sun’s corona: millions of degrees!

Mysterious, this source of heat that drives the solar wind our way …

High-speed jets, coronal loops and nanoflares may be at play.

What a thrill to gaze through space with spectrographic eyes,

Fueled by human wonder and a zeal to probe the skies.
