Explanation:
Star clusters, planets, and a red giant posed 
for this portrait of the 
night sky from rural 
Jasper County, Iowa, USA. 
 
Astrophotographer 
Stan Richard recorded the four minute 
time exposure looking east around midnight on September 3rd at 
Ashton-Wildwood Park. 
 
To avoid 
star 
trails, his camera was mounted on a 
barndoor-style 
tracker to compensate for the Earth's 
rotation. 
 
Can you identify his celestial subjects?

The Pleiades and 
Hyades, 
the closest open or galactic 
star clusters 
to the Sun, should be recognizable to beginning 
stargazers. 
 
Of course gas giant 
Jupiter 
rules as the brightest object in the picture 
and the largest planet in the Solar System, 
but second largest planet 
Saturn is 
also visible nearby. 
 
For sheer size cool 
red 
giant star Aldebaran is more impressive though, 
spanning about forty times the diameter of the Sun. 
 
Sixty light-years away and yellowish in this picture, 
Aldebaran is known as Alpha Tauri, the brightest star 
in Taurus, the Bull.
