Planet of the Tajinastes

Explanation: What bizarre planet are these alien creatures from? It's only planet Earth , of course. The planet's home galaxy the Milky Way stretches across a dark sky in the panoramic, fisheye all-sky projection composed with a wide lens. But the imposing forms gazing skyward probably look strange to many denizens of Earth . Found on the Canary Island of Tenerife in the Teide National Park, they are red tajinastes , flowering plants that grow to a height of up to 3 meters. Among the rocks of the volcanic terrain , tajinastes bloom in spring and early summer and then die after a week or so as their seeds mature. A species known as Echium wildpretii , the terrestrial life forms were individually lit by flashlight during the wide-angle exposures.
