The US National Science Foundation, a state-funded entity, has financed the Daniel K. Inouye Solar Telescope in Hawaii, which recently captured the most detailed images of the Sun's surface to date. These observations, published in Nature, promise advances in predicting space weather, a development with significant implications for protecting the infrastructure upon which global capital relies.
The imagery reveals a section of the Sun approximately 5,000 by 3,500 kilometers in size, showing its photosphere constantly churning with hot, glowing plasma. Astrophysicist Michael Wheatland from the University of Sydney described the resolution as "just incredible," noting that "we've never observed the Sun at that resolution" before.
Researchers observed the plasma undergoing Kelvin-Hemholtz instability, a physical process seen in various fluids on Earth, driven by differences in temperature, density, or speed. On the Sun, these differences stem from changes in magnetism, a phenomenon Wheatland confirmed as "completely unambiguous" in the new data.
This mixing of fluid and magnetic fields could explain the extraordinary heat of the Sun's corona, its outer atmosphere, which reaches 2 million degrees Celsius, far hotter than the surface's 5,500 degrees. Understanding these dynamics is crucial for predicting space weather, which can impact Earth's technological systems.
State-Backed Science
The Daniel K. Inouye Solar Telescope, named after Daniel Inouye, who represented Hawaii in the US Senate from 1963 to 2012, operates under the direct purview of the US National Science Foundation. This direct state investment ensures that advanced scientific infrastructure, too costly for private ventures, is developed and maintained, ultimately serving broader societal interests that often align with capital's stability.
Hannah Schunker, an astrophysicist at the University of Newcastle, highlighted the Sun's unique role as an "astrophysical laboratory" due to its proximity to Earth, a mere 149 million kilometers away. She noted the specialized filters, cooling systems, and instruments required for safely observing the Sun, underscoring the significant material and intellectual investment necessary for such research.
Labor Behind the Lens
Friedrich Woeger, a senior scientist at the US National Solar Observatory and co-lead author, revealed that preparing for and analyzing these observations demanded "months of work" from the scientific team. Despite the extensive labor, the actual data acquisition for the study spanned "not much longer than five minutes," illustrating the intensive, often unseen, human effort behind scientific breakthroughs.
Schunker stressed the importance of understanding the Sun's magnetic field, as it drives all space weather. She explained that these "very small-scale changes" on the surface are responsible for "all the larger scale things happening in the atmosphere," which have previously been unobservable.
Capital's Cosmic Forecast
The ultimate goal of this research, according to Schunker, is to integrate "small-scale physics" into "larger-scale models" to achieve "better weather predictions, better predictions of flares, [and] better predictions of how heat is transported up to the corona." These predictions are vital for safeguarding satellites, communication networks, and power grids – critical infrastructure largely owned and operated by private corporations or essential for the functioning of the global capitalist economy.
Woeger indicated plans for future measurements with instruments providing more information on plasma velocities and magnetic fields, aiming for observations of larger sections of the Sun's surface. Wheatland concluded that such progress would address "some of the big, outstanding questions in solar physics," questions whose answers increasingly serve the predictive needs of a technologically dependent economic order.
