Only a few months after its launch, ESA's Solar Orbiter has captured images of the sun from a previously unattainable distance. Among other things, these images reveal structures in the sun's atmosphere that could possibly be interpreted as so-called nanoflares, very small bursts of radiation. The images from the six remote sensing instruments published today were taken in the days before and after 15 June, when the spacecraft reached the point closest to the sun on its current orbit. Only 77 million kilometres separated the probe from our star. Although this early mission phase is primarily aimed at commissioning the instruments, the data already provide impressive evidence of Solar Orbiter's uniquely comprehensive view of the sun—from the magnetic fields at the surface to the particles streaming into space. The Max Planck Institute for Solar System Research (MPS) in Germany is an important partner of the mission and is significantly involved in four of the instruments.
