NASA’s Parker Solar Probe made history with the closest-ever approach to the sun last December, and we’re finally getting a look at some of the images it captured. The space agency released a timelapse of observations made using Parker’s Wide-Field Imager for Solar Probe (WISPR) while it passed through the sun’s corona (the outer atmosphere) on December 25, 2024, revealing up close how solar wind acts soon after it’s released. The probe captured these images at just 3.8 million miles from the solar surface. To put that into perspective, a NASA video explains, “If Earth and the sun were one foot apart, Parker Solar Probe was about half an inch from the sun.”

The probe got an unprecedented view of solar wind and coronal mass ejections (CMEs) during the approach, which could be invaluable for our understanding of space weather. “We are witnessing where space weather threats to Earth begin, with our eyes, not just with models,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters. After completing its December flyby, the Parker Solar Probe matched its record distance from the surface in subsequent approaches in March and June. It’ll make its next pass on September 15.
