![]() The ESA said the imagery would allow space experts to understand for the first time how events like these connect to the solar disc. However, in this instance, the coronal mass ejection was traveling away from us. The ejections also cause the northern lights. If these ejections are directed toward Earth, they can disrupt technology reliant on satellites. Solar prominences are often associated with coronal mass ejections, a hugely energetic explosion of light, solar material and energy from the Sun. Webb telescope's first test images include an unexpected 'selfie' This image gave an early indication of the primary mirror alignment to the instrument. In this case, the bright segment was pointed at a bright star, while the others aren't currently in the same alignment. ![]() This configuration is not used during scientific operations and is used strictly for engineering and alignment purposes. This "selfie" was created using a specialized pupil imaging lens inside of the NIRCam instrument that was designed to take images of the primary mirror segments instead of images of space. “At closest approach on 26 March, which will see the spacecraft pass within about 0.3 times the Sun-Earth distance, the Sun will fill a much larger portion of the telescope’s field of view.”ĮSA described solar prominences as “large structures of tangled magnetic field lines that keep dense concentrations of solar plasma suspended above the Sun’s surface, sometimes taking the form of arching loops.” ![]() “Right now, there is still a lot of ‘viewing margin’ around the disc, enabling stunning detail to be captured by FSI out to about 3.5 million kilometres, equivalent to five times the radius of the Sun,” ESA said. The Full Sun Imager is designed to capture the full solar disc even during close passages of the sun. ![]() The image was taken by the Full Sun Imager of the Extreme Ultraviolet Imager onboard the Solar Orbiter. The solar eruption took place on February 15 and extended millions of miles into space.

NASA's Perseverance Mars rover took a selfie with the Ingenuity helicopter, seen here about 13 feet (3.9 meters) from the rover. ![]()
