The new image of the sun is different from anything we’ve seen before

Filled with 83 million pixels, the mosaic image provides an unprecedented view of the sun and its turbulent outer atmosphere.

The Solar Orbiter took about four hours to capture all 25 images that make it up mosaicwho shows the sun? Of March 7, 2022. At that time, the probe was 46 million miles (75 million km) from the Sun, which puts it about halfway between earth and starsaccording to the European Space Agency see press. Launched in February 2020, the Solar Orbiter makes a series of eccentric solar orbits as it gets closer to our parent star.

The 25 frames, captured by the probe’s Ultraviolet Imager (EUI) instrument, provide an unprecedented view of the Sun. EUI captures images at a wavelength of 17 nm, The extreme ultraviolet region of the electromagnetic spectrum. The European Space Agency said it was the highest-resolution image ever of the full solar disk and the sun’s corona, or upper atmosphere.

Very high accuracy. The stunning mosaic image consists of a 9148 x 91112 pixel grid, which according to the European Space Agency is 10 Times better than a 4K TV. This amounts to 83 million pixels. ESA sends file interactive drawing This allows you to scroll through the scene, and you can zoom in and out to capture some of the finer details. High resolution images can be found, which I already use as my desktop background here.

On the top right and bottom left, a terrifying dark thread could be seen. These filaments can produce powerful volcanic eruptions, as large amounts of coronal gas fall into space. This explosion, if aimed at Earth, sometimes creates solar storms around our atmosphere.

Another tropical solar-powered instrument, Spectral Environment Coronal Imaging (SPICE), also provides useful data. SPICE looks deeper into the sun, at the lower layer known as the chromosphere, and does so by scanning different wavelengths of intense ultraviolet radiation produced by different atoms.

New In Spice Released gifthe purple region corresponds to hydrogen gas at temperatures up to 18,000 ° F (10,000 ° C), green with oxygen at 576,000 ° F (320,000 ° C), and yellow to neon at 1.13 million degrees Fahrenheit (630,000 degrees Celsius).

A great benefit of SPICE is that it allows scientists to link surface eruptions to these deeper layers And to investigate the curious observation that the surface of the Sun is about 9,000°F (5,000°C) colder than the oceans. Corona, which can reach 1.8 million degrees Fahrenheit (one million degrees Celsius).

Interestingly, the Sun Orbiter Now only a few more days to make it The first pass is close to the sunwhich will happen on March 26, 2022. All 10 Many of the probe instruments will be active at that time, as European Space Agency scientists try to extract as much data as possible from the flyby. The sun’s orbit is now in an orbit that makes it closer to the sun than Mercury. The probe will gradually approach Over the next few years, as its direction gradually increases, which allows us to peer into the polar regions of the sun.
