Growth rings on a tree from Tunguska
Growth rings on a larch tree after the Tunguska impact. The increased diameter of each successive ring shows the growth of the tree in a year. This cut supports the hypothesis that growth increased after the Tunguska explosion. In 1908 a large astronomical body exploded above Tunguska, Siberia, Russia. The energy released was equivalent to around 1000 times that of the Hiroshima atomic-bomb. 60 million trees were destroyed by the explosion, and accelerated growth in those remaining is probably due to less competition for light and fertilisation from the ash of the destroyed trees

EDITORS COMMENTS
This print showcases the intricate growth rings on a larch tree from Tunguska, offering a glimpse into the aftermath of an extraordinary event. The Tunguska impact refers to the massive explosion caused by a celestial body in 1908 above Siberia's remote region, releasing an astonishing amount of energy comparable to 1000 Hiroshima atomic bombs. In this image, each successive ring represents one year of the tree's growth, and their increased diameter provides evidence supporting the hypothesis that growth accelerated after the catastrophic incident. The destruction caused by this astronomical event wiped out approximately 60 million trees in its path. However, those remaining experienced enhanced development due to reduced competition for sunlight and nutrients resulting from ash fertilization left behind by destroyed trees. The monochromatic tones add depth and intensity to this botanical marvel captured by Science Photo Library. It serves as a testament to nature's resilience and adaptation even in the face of such immense devastation. This photograph not only highlights the biological significance of growth rings but also offers us insight into our planet's history during the early 20th century when humanity witnessed one of its most powerful natural events.
