NGC7129 is an open cluster star-forming region in a reflection nebula located at constellation Cepheus and lies some 3000 light-years away from the earth.
Astronomers estimate that many of the bright stars that form the cluster are younger than 1 million years old. These young stars are very energetic and emit large amounts of radiation that break apart clouds of gas that surround them. Some parts within the nebula glow pink due to the excited hydrogen gas in the region.
