The elliptical galaxy M60 was discovered by Johann Koehler just days before Messier himself observed it. It is the third-brightest giant elliptical galaxy in the Virgo cluster and contains about a billion times the mass of our Sun.
Notably, M60 appears to be close to the spiral galaxy NGC 4647. However, there doesn't seem to be any evidence that these two galaxies are actually interacting. New data from the Hubble Space Telescope seems to suggest that the interaction has only just begun.
Visible in this image within the disk of NGC 4647 is the supernova SN 2022hrs that occurred on April 16, 2022. You can see below the progression that the supernova took, being very bright at first and dimming over the course of four months.

Put briefly, the "Super M60" was an upgrade for the M60 offered by Teledyne Continental Motors' General Products Division. It offered increased levels of armor protection, a much more powerful engine, improved transmission, a lower profile cupola, while also incorporating the AN/VVS-2 thermal imaging system and AN/VVG-2 laser rangefinder from the M60A3 TTS. Only one prototype was ever made due to a lack of orders or interest domestically and internationally.
