![]() "In March 2022, we'll get into the full-blown science phase with unprecedented resolution," Müller said during Thursday's teleconference. It will also get about 10 million miles closer to the sun, improving the image detail and quality. The orbiter is in its cruise phase and will eventually reach speeds as fast as the sun's rotation, allowing it to closely track particular spots on the solar surface for an extended period of time. The spacecraft will look for the source of this stream. ![]() One of the Solar Orbiter's primary goals over the next two years is to study solar wind: a stream of electrically charged particles that surges from the sun and washes over the planets. Solar Orbiter/EUI Team PHI Team/ESA & NASA The first two show different regions of the sun's atmosphere, and the last three show the sun's velocity, magnetic properties, and visible light. This animation shows five views of the sun captured with the Extreme Ultraviolet Imager and Polarimetric and Helioseismic Imager instruments on the Solar Orbiter on May 30, 2020. The EUI takes images in the extreme ultraviolet at a wavelength of 17 nanometers. The smallest campfire features, which are each about two pixels wide in the images (arrow in the above image), are about the size of Europe, Berghmans said Thursday. The image was taken in the extreme ultraviolet by Solar Orbiter’s Extreme Ultraviolet Imager (EUI) instrument. "The sun might look quiet at the first glance, but when we look in detail, we can see those miniature flares everywhere we look." "The campfires are little relatives of the solar flares that we can observe from Earth, million or billion times smaller," David Berghmans, who leads the team behind the high-resolution imaging instrument on the spacecraft, said in the release. Telescopes have recorded images of solar eruptions as far back as 1900.īut they didn't know that the solar surface was covered in them because no telescope had been powerful enough to image them at such a high resolution. Scientists have long known that solar flares exist.

Venus and Mars are not globally magnetized, but all four outer planets are, said MIMI. Not all planets have this protective force field. The circle in the lower right corner indicates the size of Earth for scale. The solar wind can strip atmospheres from worlds, but like Earth, Saturn has a natural shield called a magnetosphere, which Cassini’s Magnetosphere Imaging Instrument, known as MIMI, was sent to study. ![]() It often indicates a user profile.Ī high-resolution image from the Extreme Ultraviolet Imager on the Solar Orbiter spacecraft, taken May 30, 2020.
