Problems of the highest interest in the physics of our sun are connected, doubtless, with the varying forms which the coronal light is known to assume. The naked-eye observations of total eclipses, some recorded with spectacular detail in artists paintings, reveal structure that is consistent with images. In the images obtained by Solar Orbiter during its first close pass in June 2020, scientists discovered miniature solar flares dubbed campfires. The SPICE measurements revealed individual layers of the sun's atmosphere, starting with the lowest layer, the chromosphere, at 18,000 degrees F (10,000 degrees C), all the way up to 1,130,000 degrees F (630,000 degrees C) in parts of the corona. While the sun's surface is "only" about 9,000 degrees Fahrenheit (5,000 degrees Celsius), the temperature of the outer atmosphere, the corona, soars to nearly 1.8 million degrees F (1 million degrees C). The Solar Orbiter is watching a new sun weather cycle begin. Solar Orbiter spacecraft sends postcard from Venus in flyby video European sun probe flew through the tail of Comet Leonard The gravitational field of the sun will focus light from a distant source to a. NASA's Parker Solar Probe makes deeper dives toward the star, up to a few million miles away, but due to the extremely high temperatures at those distances, the spacecraft can't carry a sun-facing camera. Brightness of solar corona compared to the sky brightness during the day. No other spacecraft equipped with a camera has ever gotten this close to the sun. Solar Orbiter's distance from the star will then start to increase again, but its future close passes will take it even closer: just 26 million miles (42 million km) away from the sun's surface. On Saturday (March 26) at 7:50 am EDT (1150 GMT), the spacecraft will zoom past the sun at a distance of only 30 million miles (48.3 million km), about a third of the sun-Earth distance, ESA's Solar Orbiter deputy project scientist Yannis Zouganelis told. While the two previous perihelions - the points in the spacecraft's elliptical orbit closest to the sun - took place at about half the sun-Earth distance (47.8 million miles or 77 million km), Solar Orbiter is now heading for a much closer encounter. ![]() Since the spacecraft's launch in February 2020, ground control teams have been gradually tightening Solar Orbiter's trajectory around the star at the center of our solar system. ![]()
