Open cluster M38, seen here at the middle-right of the image, can be seen with binoculars toward the constellation of Auriga. M38 is considered an intermediately rich open cluster of stars, each of which is about 200 million years old. Located in the disk of our Milky Way galaxy, M38 is still young enough to house many bright blue stars, although it's brightest star is a yellow giant shining 900 times brighter than our Sun. The cluster spans roughly 25 light-years and lies about 4000 light-years away. Loosely bound by gravity, open clusters spread out over time as they orbit the galactic center and their member stars slowly escape. https://apod.nasa.gov/apod/ap030107.html)
NGC 1907 is an open star cluster around 4,500 light years from Earth. It contains around 30 stars and is over 500 million years old. With a magnitude of 8.2 it is visible as part of the constellation Auriga
The star field is embedded in reddish clouds, which are erroneously shown as bright red in many images. Their true color is reflected well in this image, loyally conveying the green and blue colors that make up these emissions.
The possible physical relation between the closely projected open clusters NGC 1912 (M 38) and NGC 1907 is investigated. Previous studies suggested a physical pair based on similar distances, and the present study explores in more detail the possible interaction. Spatial velocities are derived from available radial velocities and proper motions, and the past orbital motions of the clusters are retrieved in a Galactic potential model. Detailed N-body simulations of their approach suggest that the clusters were born in different regions of the Galaxy and presently experience a fly-by. https://arxiv.org/abs/astro-ph/0205100)
