NGC 5793 is an active spiral galaxy located approximately 150 million light years away in the constellation Libra. It is classified as a seyfert galaxy and was discovered by Francis Leavenworth in 1886.[3][4]
In 2014, the Hubble Space Telescope examined and photographed NGC 5793.[3]
Seyfert galaxies such as NGC 5793 are known to house megamasers, these megamasers are capable of having a luminosity of thousands of times greater than the Sun.[3]
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 size of ≈200 cm -3.[5]
