NGC 4774, also known as the Kidney Bean Galaxy,[2] is a ring galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 8581 ± 24 km/s, which corresponds to a Hubble distance of 126.56 ± 8.87 Mpc (∼413 million light-years).[1] It was discovered by German-British astronomer William Herschel on 17 March 1787.[2]

Two supernovae have been observed in NGC 4774: SN 2013he (type II-P, mag. 16.5),[3] and SN 2021cjd (type II-P, mag. 20.2).[4]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
