foreground star造句

The bright object in the center is a foreground star.

Follow-up observations by Hubble Space Telescope in 2005 separated the light of the slightly offset foreground star from the background star.

Of course, the nebula is itself a star-forming region, but the stars that appear and disappear here include background and foreground stars that by chance lie along the same line of sight.

Intriguing background galaxies are scattered around the field that also includes spiky foreground stars.
