These incredible photographs of clouds forming over the iconic volcanoes of Kamchatka in eastern Russia will make you think you've seen a UFO.

Lenticular clouds are gently curved layer clouds most common near or downwind of mountain ranges during the winter and spring when upper winds are typically strongest.
Vladimir Voychuk, a 35-year-old photographer from Klin, Russia, captured these amazing images of lenticular clouds, often called spaceship clouds because of their out-of-this-world shapes.
"It's not the first time I've seen clouds like this, but it's the first time I've been able to catch it on film," he said.
Their "flying saucer" appearance is owed to the forced ascent of stable air over mountain ranges. As long as the ambient weather conditions (winds, humidity) are unchanged, the cloud won't move, appearing to hover near the mountain range.
Kamchatka has a little something extra to add to the mix because of the volcanic activity in the area. Voychuk's favorite photo shows two clouds forming around the Klyuchevskaya Sopka volcano.
"Taking that picture took my breath away," he said. "It's a pretty rare thing to capture on film because the cloud was formed not only by vapour but also the smoke coming out of the active volcano."
Voychuck, who travels thousands of miles to Kamchata, says that it's one of his favorite places to take pictures.
"It takes me a long time to get there but it's always worth it," he said. "I don't think there's anywhere in the world that's better."
