Solar Orbiter's pictures of the sun are every bit as dramatic as you were hoping

On March 26, the ESA's Solar Orbiter made its closest approach to the sun so far. It ventured inside Mercury's orbit and was about one-third the distance from Earth to the sun. It was hot but worth it.
The Solar Orbiter's primary mission is to understand the connection between the sun and its heliosphere, and new images from the close approach are helping build that understanding.
According to the ESA, the Solar Orbiter is the most complex scientific laboratory ever sent to the sun. It carries a robust suite of instruments, including a magnetometer, the Extreme Ultraviolet Imager, the Solar Wind Plasma Analyzer, and others. Its broad range of instruments allows it to observe solar events in multiple ways.
The spacecraft benefits from getting as close to the sun as it can. But close approaches make the Solar Orbiter hot. The spacecraft's first line of defense is its heat shield. It's a multi-layered titanium device mounted on a honeycomb aluminum support, with carbon fiber skins designed to shed heat. Between all that and the spacecraft's body, there are another 28 layers of insulation.
