In a historic mission, NASA's Parker Solar Probe has captured remarkable data on the Sun's corona, a superheated gas halo extending millions of miles into space. A research team led by the University of Arizona has now analyzed these findings, shedding light on the behavior of hot plasma near the Sun's surface and its profound implications for space weather prediction.

Why it matters

Understanding the Sun's atmosphere is crucial for predicting the timing and nature of solar disturbances reaching Earth, which can impact communications satellites and increase radiation exposure for aircraft. The Parker Solar Probe's close-range readings have allowed researchers to study these regions directly, offering the clearest glimpse yet into the formation of the solar wind.

The details

Launched in 2018, the Parker Solar Probe is on a looping journey around the Sun, utilizing gravity assists from Venus. During its record-breaking close pass, just 3.8 million miles from the solar surface, the probe captured high-resolution data on the Sun's corona. This region exhibits surprising thermal behavior, with plasma moving outward from the Sun's core cooling significantly in the visible photosphere, then unexpectedly heating up again in the outer corona. To interpret the probe's data, the research team developed the Arbitrary Linear Plasma Solver (ALPS), a new computational tool that enables them to analyze how individual particles respond to waves moving through the Sun's plasma.

  • The Parker Solar Probe was launched in 2018.
  • The probe made its record-breaking close pass to the Sun in 2026.

What they’re saying

“We know there's this constant heat being input into the solar wind, and we want to understand the mechanisms driving that heating.”

— Kristopher Klein, Physicist, Lunar and Planetary Laboratory

What’s next

The research team plans to continue analyzing the Parker Solar Probe's data to further refine models of solar weather and its impact on Earth and other celestial bodies.

The takeaway

The Parker Solar Probe's unprecedented data has the potential to significantly enhance our understanding of the Sun's atmosphere and improve our ability to predict the timing and nature of solar disturbances, which can have significant impacts on Earth and beyond.
