MAMMOTH-1 is a large ultraluminous lyman Alpha emitting radio-quiet nebula located near the center of a massive galaxy overdensity named BOSS1441 at a redshift distance of z= 2.32. The nebula has a size of 450 kiloparsecs making it one of the largest lyman-alpha nebula known comparable or even larger than the Slug nebula. [1] [2]

As of to date, this nebula has the highest lyman alpha luminosity of any nebula with a luminosity of 5.2x10^44 ergs. [3]
