NASA photographed Christmas Tree star cluster with 'decorations'

According to NASA (National Aeronautics and Space Administration) the photo of the Christmas Tree Star cluster was taken by its Spitzer infrared space telescope.

Astronomers say this cluster represents the best “laboratory to date for studying the physics of star formation”. The infant stars, which were discovered in 2006, appear as pink and red specks.

NASA also explained that the most visible-light stars “which gave the Christmas Tree Cluster its name and triangular shape do not shine brightly in Spitzer’s infrared eyes”.
