NASA and the ESA’s Solar Orbiter may not be fully operational yet, but that hasn’t stopped the Sun probe from capturing one of its first gushes of magnetically-charged plasma from the corona of our nearest star. It’s among the first data tidbits from the spacecraft after a long year of travel from Earth to the Sun, where scientists expect it to help answer lingering questions about the impact of solar activity on our planet.
