That is the goal of ESA\u2019s new Proba-3 mission, which has just launched on a quest to unlock the secrets of our Sun!\u00a0<\/p>\n<p><b>Our mysterious Sun\u00a0<\/b><\/p>\n<p>Have you ever witnessed a solar eclipse? When the Moon blocks the Sun, it reveals the Sun\u2019s faint outer atmosphere, called the corona. This mysterious region is millions of degrees hotter than the Sun\u2019s surface \u2014 a puzzle that scientists are trying to solve. Huge explosions called Coronal Mass Ejections also blast out from the corona, causing problems for astronauts, satellites, and even power grids on Earth. However, the corona is a million times fainter than the Sun, and is only visible for a few minutes during a solar eclipse. This makes studying it very difficult.\u00a0<br \/>\u00a0<br \/>Enter the Proba-3 mission! It is a pair of satellites that will soon begin working together to solve this challenge.\u00a0<\/p>\n<ul>\n<li>\n<p>The Occulter satellite has a large circular disc to block the Sun\u2019s dazzling light, creating an artificial eclipse that will be seen by its partner.\u00a0<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li>\n<p>The Coronagraph satellite carries a special telescope to study the Sun\u2019s corona in detail.\u00a0\u00a0<\/p>\n<\/li>\n<\/ul>\n<p>Together, these innovative satellites will create long-lasting eclipses in space, allowing scientists to observe the corona for up to six hours at a time!\u00a0<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"6336\" data-credit=\"ESA - P.
