On 26 March, Solar Orbiter reaches another mission milestone: its first close perihelion. This will make it easier to compare results from different instruments and observatories in future. The images were taken on 7 March, precisely when Solar Orbiter crossed the Sun-Earth line, so the images can be compared with Earth-bound solar instruments and cross-calibrated.

Investigating this mystery is one of the key scientific objectives of Solar Orbiter. But above the Sun, the corona reaches a million degrees Celsius whereas the surface is only about 5000☌. Usually the temperature drops as you move away from a hot object. These ‘prominences’ are prone to erupt, throwing huge quantities of coronal gas into space and creating ‘space weather’ storms. This reveals the Sun’s upper atmosphere, the corona, which has a temperature of around a million degrees Celsius.Īt the 2 o’clock (near the image of the Earth for scale) and 8 o’clock positions on the edges of the Sun, dark filaments can be seen projecting away from the surface.

For comparison, this image has a resolution that is ten times better than what a 4K TV screen can display.ĮUI images the Sun at a wavelength of 17 nanometers, in the extreme ultraviolet region of the electromagnetic spectrum. In total, the final image contains more than 83 million pixels in a 9148 x 9112 pixel grid.

Taken one after the other, the full image was captured over a period of more than four hours because each tile takes about 10 minutes, including the time for the spacecraft to point from one segment to the next. The high-resolution telescope of EUI takes pictures of such high spatial resolution that, at that close distance, a mosaic of 25 individual images is needed to cover the entire Sun. But he noted that Parker was moving so fast it covered a vast distance during that time, tearing along at more than 62 miles (100 kilometers) per second.The images were taken when Solar Orbiter was at a distance of roughly 75 million kilometres, half way between our world and its parent star. “The first and most dramatic time we were below for about five hours … Now you might think five hours, that doesn’t sound big,” the University of Michigan’s Justin Kasper told reporters. The spacecraft dipped in and out of the corona at least three times, each a smooth transition, according to scientists. Launched in 2018, Parker was 8 million miles (13 million kilometers) from the center of the sun when it first crossed the jagged, uneven boundary between the solar atmosphere and outgoing solar wind.

“Fascinatingly exciting,” said project scientist Nour Raouafi of Johns Hopkins University. Scientists said it took a few months to get the data back and then several more months to confirm.

The Parker Solar Probe actually flew through the corona in April during the spacecraft’s eighth close approach to the sun. Scientists announced the news Tuesday during a meeting of the American Geophysical Union.
