The main astronomical event of autumn 2025 was the visit of comet C/2025 A6 (Lemmon) to the inner Solar System. On October 21, it passed at a minimum distance of 0.60 AU (90 million km) from Earth.
The comet is now rapidly approaching the perihelion of its orbit. As it heats up, the nucleus of C/2025 A6 (Lemmon) is releasing more and more gas and dust. This is causing its brightness to increase and its tail to grow. At the moment, the comet’s brightness has reached +3.5 magnitude. If you move beyond the city lights, the comet can be seen even with the naked eye. Astrophotographers around the world are actively taking advantage of this circumstance, photographing C/2025 A6 (Lemmon). The editors of Universe Space Tech have compiled the best images of the tailed visitor taken in recent days.
