NGC 2300 is a lenticular galaxy in the constellation Cepheus.[2] Its velocity with respect to the cosmic microwave background is 1876 ± 7 km/s, which corresponds to a Hubble distance of 90.2 ± 6.3 Mly (27.67 ± 1.94 Mpc).[2] However, 11 non redshift measurements give a distance of 131.98 ± 21.75 Mly (40.464 ± 6.668 Mpc).[5] The galaxy was discovered in 1871 by French astronomer Alphonse Borrelly using an 18 cm telescope.[4]

Together with NGC 2276, they form the 114th object in Halton Arp's Atlas of Peculiar Galaxies.[6]

According to the SIMBAD database, NGC 2300 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[1]

One supernova has been observed in NGC 2300: SN 2024uai (type Ia-91bg-like, mag. 16.58).[7]

Model of protein allosteric regulation Not to be confused with Morphine. Proteins that function as morpheeins are illustrated using a dice analogy where one dice can morph into two different shapes, cubic and tetrahedral. The illustrated assemblies apply a rule that the dice face with one spot must contact the dice face with four spots. To satisfy the rule for each dice in an assembly, the cubic dice can only form a tetramer and the tetrahedral dice can only assemble to a pentamer. This is analo…
