![]() The eruption turned out to be one of the largest, strongest solar eruptions on record, Nature reported. Then, one area it had wriggled away from suddenly detonated. In September 2022, Solar Orbiter was tracing the giant “snake” of solar plasma along a curling magnetic field filament at around 170km per second. It wasn’t the last barrage the little craft would withstand. The 2021 event marked a novel type of measurement, according to researchers. The two craft also measured a huge eruption on the far side of the sun that landed a direct hit on the Parker Solar Probe. Noticing the opportunity, the agencies worked together to collect the first measurements on how fast temperatures rise from the Sun’s surface into its atmosphere. Once, in June 2022, the two spacecraft passed closely together. The Solar Orbiter maintains more distance, but its high-definition cameras capture spectacularly detailed images. The NASA craft passes closer to the Sun’s surface on an elliptical orbit, skimming the atmosphere to closely monitor particle releases and magnetic fields. NASA’s Parker Solar Probe and the European Space Agency (ESA)’s Solar Orbiter didn’t launch under any causal connections - but now, together, they help lead the field. Solar observatories are proliferating, but the tandem work of two particular satellites has caused a spike in interest. ![]() “We are living in a paradigm-shifting moment for this field,” said Dan Seaton, a solar physicist at the Southwest Research Institute in Boulder, Colo. ![]() Booming solar eruptions have caused heat and energy to ripple through the star’s atmosphere, while a “slithering magnetic ‘snake’” writhed along its surface, as Nature put it. It’s been a colorful field of study since the record-breaking solar storms began some years ago. It’s also initiated a restructure of solar physics as we know it, one researcher in the field told the journal Nature. That’s resulted in a torrent of amazingly high-resolution solar images. The Sun’s surface, as the Solar Orbiter sees it.
