NGC 5793 is an active spiral galaxy located approximately 150 million light years away in the constellation Libra. It is classified as a Type 2 Seyfert galaxy[4] and was discovered by Francis Leavenworth in 1886.[1][7] The galactic plane is inclined at an angle of 73°, giving it an oval, nearly edge-on appearance with the major axis aligned along a position angle of 150°.[4]

Seyfert galaxies such as NGC 5793 are known to house megamasers. Megamasers can have a luminosity of thousands of times greater than the Sun.[1] Neutral hydrogen has been detected against the galactic nucleus. This means that NGC 5793 has an estimated HI cloud size of ≈15 pc and an estimated atomic gas density of ≈200 cm -3.[8]
