Explanation:
Yes, but can your tree do this?
Pictured is a visual coincidence between the
dark branches of a nearby tree and bright glow of a distant aurora.
The beauty of the
aurora -- combined with how it seemed to mimic a
tree right nearby --
mesmerized the photographer to such a degree that he momentarily forgot to take pictures.
When viewed at the right angle, it seemed that this tree had aurora for leaves.
Fortunately, before the aurora morphed into a
different
overall
shape,
he came to his senses and capture the awe-inspiring
momentary coincidence.
Typically triggered by
solar explosions,
aurora are caused by high energy
electrons
impacting the
Earth's atmosphere around 150 kilometers up.
The unusual Earth-sky collaboration was witnessed in March of 2017 in
Iceland.
