APOD: 2023 March 13 Б Rainbow Tree
13.03.2023

Once Upon a Solstice Eve
23.12.2016

Once upon a solstice eve a little prince gazed across a frozen little planet at the edge of a large galaxy.

Sea and Sky Glows over the Oregon Coast
28.08.2018

Every step caused the sand to light up blue. That glow was bioluminescence -- a blue radiance that also lights the surf in this surreal scene captured last month at Meyer's Creek Beach in Oregon, USA. Volcanic stacks dot the foreground sea, while a thin fog layer scatters light on the horizon.
