The oldest recorded sense of corona in English refers to the projecting, slab-like part of a classical cornice. These applications of corōna informed the earliest uses of the word in English. Outside of literal crowns worn on the head, the Latin corōna could be used for various things that resemble crowns in their form, including cornices and the halo around the sun. This crown became a symbol for emperors and appeared on coins. It was also known as corōna querca, or “oak crown,” because it was made with oak leaves. One especially high honor was the corōna cīvica (“civic crown”), bestowed on a citizen who saved a fellow citizen’s life. For instance, the corōna mūrālis, or “walled crown,” was a gold crown fashioned in the shape of battlements and was awarded to a soldier who was the first to enter a besieged town or fortress. Priests donned corōnae when performing important rituals and sacrifices.ĭifferent types of corōna were used as military decorations honoring various acts of bravery.

People wore corōnae of flowers at festivals, for example, or used them to ornament images of gods. Back then, a corōna served various ceremonial and symbolic functions. Let’s start with a glimpse into life in ancient Rome. A verb form of corōna was corōnāre, “to crown, wreathe,” ultimate source of the English coronation, “the act or ceremony of crowning a king, queen, or other sovereign.” It was borrowed directly from the Latin corōna, meaning “garland, wreath, crown.” Its plural form is corōnae. The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.Flowers and crows, priests and soldiers, suns and moons, kings and queens, lagers and viruses? What could all these disparate things possibly have in common? Well, in one way or another, they are involved in the rich history of the word corona.Ĭorona entered English around 1555–65. It usually appears around the footprints, referred to by solar physicists as footpoints, of large coronal loops that are too hot to be seen in the EUI images. As gas flows around the loops and cools back down on its way to the surface it creates the phenomenon called coronal rain.Īnother intriguing feature of this image is the bright gas that makes delicate, lace-like patterns across the Sun. Active regions are where the Sun’s magnetic field bursts out from its interior in loops that rise into the atmosphere.

This movie shows FSI’s view of the Sun before zooming in on an active region with HRI EUV. On 17 March, Solar Orbiter was at roughly a third of the Earth’s distance from the Sun (0.378 AU), and heading for a close approach on 26 March, placing its payload closer to the Sun than any previous solar telescope.

EUI takes both full disc images using the Full Sun Imager (FSI) telescope, as well as detailed images of a smaller region using the High Resolution Imager (HRI EUV) telescope.

Known as the corona, this layer of the Sun’s atmosphere exists at a temperature of around one million degrees. This is an extreme ultraviolet wavelength of light that is emitted by the upper atmosphere of the Sun. It shows the Sun’s appearance at a wavelength of 17 nanometers. The Extreme Ultraviolet Imager (EUI) on the ESA/NASA Solar Orbiter spacecraft captured this movie on 17 March 2022.
