2MASS J20395358+4222505

An image of the región Cygnus-X close to the association Cygnus OB2. 2MASS J20395358+4222505 is the star framed above the cloud of ionised gas (in green in the image) and can be seen in the zoomed-in image. The red colour shows that the star must be heavily obscured by dust, because instrinsically the star must be blue, due to its high surface temperature (close to 24,000 degrees).
