Explanation:
Have you ever seen the
Summer Triangle?
The bright stars
Vega,
Deneb, and
Altair form a large triangle on the sky
that can be seen rising in the northern spring during the morning, and
rising in the northern fall during the evening.
During summer months, the
triangle can be found nearly overhead near midnight as three of
the brightest stars on the sky.
Featured here, along with the arch of the central band of our
Milky Way Galaxy, the
Summer Triangle
asterism was captured this spring
over the Great Wall of China.
This part of the Great Wall,
a World Culture Heritage
Site,
was built during the
6th century on the
Yan Mountains.
At the summit is
Wangjinglou Tower
from which, on a clear night, the lights of
Beijing
are visible in the distance.
