Earth’s largest and most powerful solar telescope has revealed breathtaking new views of the sun’s surface.
In a series of new images, observations from the Daniel K. Daniel K. Inouye described the intricate details of sunspot regions, convective cells, and plasma motion in the solar atmosphere down to a resolution of about 20 kilometers (about 12 miles).
At these scales, the plasma structures look like brush strokes and textures on a painting. For distances in context, a single solar load cell is slightly smaller, on average, than the US state of Texas.
However, these new Inoue images aren’t just designed to make you feel insignificant and insignificant, they’re a sneak peek at the science to come, as researchers analyze the solar surface in exquisite detail to understand the processes taking place there.
Sunspots are often larger than our entire planet, usually short-lived defects where magnetic fields are unusually strong, and appear darker than their surroundings thanks to the relatively low temperatures. They are also associated with our Sun’s most violent eruptions: as magnetic field lines intertwine, snap and reconnect, they unleash incredible blasts of energy in the form of coronal mass ejections and eruptions.
Also, sunspot activity is not constant. It is associated with approximately 11-year cycles, during which sunspot and flare activity peaks at solar maximum, and decreases to almost none during solar minimum. At the solar maximum, the sun’s poles switch places; We are currently on track towards the solar maximum expected to occur in 2025, after which solar activity will start to wane again.
It is not known what drives these solar cycles, or what creates sunspots. But this information is of great importance to us here on Earth, since coronal mass ejections often associated with sunspots can send huge clouds of charged particles slamming into Earth’s magnetic field and risking a number of disruptions to our technology-dependent way of life.
Inoue’s new images show many of the delicate structures associated with sunspots.
When sunspots begin to dissolve and disappear, bridges of light can cross them.
When the sun is quiet, it can appear completely featureless in images taken in the visible part of the spectrum.
However, even the quiet sun has a lot going on. Thermal cells give the sun’s surface, or photosphere, its “popcorn-like” texture. The hot plasma rises from inside the center of the cell, then travels outward, to the periphery, and drops back down as it cools.
Scientists hope that the data from Inoue will help unravel some of the remaining mysteries of these remarkable solar phenomena. In turn, this could help to understand larger phenomena: the internal dynamics of the sun, for example, and what drives solar cycles.
