The volcano on La Palma still spits fire and ashes.
Now a geochemist on the Canary Island has succeeded in documenting a rare natural spectacle with the camera.
The glowing stone ball is a so-called lava bomb that was ejected from the crater at high speed.
A photo that the scientist posted on Twitter documents the size of the sphere.
Experts believe that the volcano will remain active for a while.
This is indicated above all by the emission of large amounts of sulfur dioxide.
The ash cloud continues to rise hundreds of meters into the sky.
The volcano erupted six weeks ago and has since covered more than 900 hectares of land with a lava crust, which in some places has piled up to 30 meters high.
