Just in time for Halloween, NASA released a photo of the sun “smiling”.
Their Solar Dynamics Observatory captured the cheery image, sharing it in a Tweet in late October.
The ‘smile’ we see here are made up of three coronal holes, solar fluctuations during which fast bursts of solar wind are released, NASA explained.
“Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.”
It reminds us of the image captured by the Hubble telescope that captured a giant smiling emoji made of stars.
Found by an amateur astronomer, the unique picture was submitted the image in NASA’s Hidden Treasures of Hubble competition. She zoomed into a galaxy cluster that appeared to smile down on Earth, with the grin formed by the distortion of light from strong gravitational lensing.
