NASA has presented an unprecedented composite image of the so-called Christmas Tree Cluster, which, contrary to its name, does not consist of Christmas trees, but of a large number of stars. Experts used different wavelengths and perspectives to capture the image, because the shape of the Christmas tree originally could not have been created so spectacularly.
The mass of the stars in the cluster is 0.1-7 solar masses, and their distance from Earth is about 2,500 light-years.
The green color in the image represents the different gases, and this data was provided by the WIYN Observatory. The white stars in the foreground and background of the image were recorded in the infrared range by 2MASS. However, what really makes the “Christmas Tree” shine is the data provided by the Chandra Space Telescope, which has already been documented in the X-ray region and flashes blue.
Just like this Space.com website It also draws attention to the fact that the pine tree-like stars in the image are still very young, so their own systems may still be forming – however, at this age, stars are vulnerable to violent X-ray bursts that can be overwhelmingly powerful. Enough to partially or completely vaporize nearby celestial bodies; So the group can still be formed in large quantities.
