An Insanely High-Resolution Image of the Sun

Our local star the Sun has been the source of many studies from ground based telescopes to space based observatories. The ESA Solar Orbiter has been approaching the Sun, capturing images along the way in unprecedented detail. It arrived at its halfway point in March last year and captured a series of 25 images. They have now been stitched together to reveal an astonishingly high resolution image. You can even zoom in to see individual granules in the solar photosphere.

The Sun dominates the Solar System in almost every way imaginable, yet much of its inner workings have been hidden from humanity. Over the centuries, and especially in the last few decades, technological advancements allowed us to ignore our mothers’ exhortations and stare at the Sun for as long as we want. We’ve learned a lot from all those observations.

A new study shows how the Sun experiences its own ‘meteor showers.’
