Short description: Lenticular galaxy in the constellation Telescopium

NGC 6861 is a lenticular galaxy located in the constellation Telescopium. It is the second-brightest object in the constellation. Unlike most lenticular galaxies, which tend to be mostly devoid of both gas and dust, NGC 6861 exhibits a thick obscuring ring of dust around the nucleus where star formation is occurring. The galaxy was discovered by Scottish astronomer James Dunlop, in 1826.^[3] NGC 6861 is interacting with NGC 6868, and it is predicted that they will eventually merge.^[4]
