Very intense and rare sky phenomenon that looks like northern lights electrifies the sky over Romania

Another impressive light show surprised Azuga skywatchers as their skies started glowing in different very intense colors – like auroras – over the Bucegi Mountains last Sunday at sunset in Romania.
These insane rainbow clouds were captured by Razvan Neagoe.
Some will say this incredible spectacle is due to sun light refracting in ice crystals. Others will say this ‘winter rainbow’ is due to chemicals sprayed in the atmosphere.

In any cases, physics and chemistry will always baffle people!
