Explanation:
The stars of a
summer night on the left and the
winter night sky
on the right are the same stars.
In fact, both pictures
were taken in late December and have similar fields of view.
The left panel shows a scene from a beach on Bruny Island off
the coast of Tasmania, Australia,
while the right panel features the sky over the
snowy Alborz Mountains of northern Iran.
But if the sky on one side still looks unfamiliar to you,
just put your cursor over the image to see an alternate version.
The alternate image will trace the outlines of the familiar
constellation
of Orion,
as seen from the southern and northern hemispheres
of planet Earth.
