From northern Europe to Australia's Tasmania, the sky-gazers last night witnessed stunning auroras that painted the skies in pink, green, and purple hues.
Auroras illuminated the skies across many regions on Saturday. This was the second time in a row on May 11 that
auroras lit up the skies across swaths of the planet.
This spectacular celestial show, which is usually confined to the far northern reaches of the planet and is called "northern lights”, is triggered by a powerful solar storm.
A report by news agency AFP stated that this powerful solar storm could also continue on Sunday.
Why do we get auroras?
The National Aeronautics and Space Administration (NASA), on Sunday, shared a thread on X (formerly Twitter) explaining the phenomenon.
NASA explained the two things that they call solar eruptions—solar flares and coronal mass ejections (CMEs).
NASA wrote, “There are two things we call solar eruptions: solar flares and coronal mass ejections (CMEs). They often occur together, but not always. Solar flares are intense flashes of light — a result of the Sun's complex magnetic fields abruptly rearranging themselves.”

NASA said that because solar flares are light, they reach Earth in about 8 minutes, while CMEs can take days to reach us. However, when they do they can set the aurora light.
“Solar flares reach us quickly — light only takes about 8 minutes to reach Earth. Because CMEs are made up of particles, they may take days to reach us. But when they do, they can set the aurora alight,” added NASA
