Description

Something has 'grazed' the globular cluster M 92.

The transit actually occurred much closer than the 26,000 light years that separate us from the star cluster: it took place either in orbit around the Earth, in the case of a satellite, or in the atmosphere, in the event of a meteor: if it was a satellite, it had a 'flare' (short exposure to the Sun) just near M 92.

In any case, the meeting seems to give a certain charm to the image of the celestial object.

The event involved a single frame out of 376, all of 30 seconds each, with which the image was built: a special processing technique made it possible to recover the trail while merging all frames together (normally the stacking program would remove it, considering it "noise").
