NGC 7049 is a lenticular galaxy of Hubble type S0 in the constellation Indus the southern sky , the 101 million light-years from an estimated Milky Way is removed. The system represents an intermediate state between a spiral galaxy and an elliptical galaxy .
It has an apparent visual magnitude of 10.6 mag and an angular extent of 4.4 '× 2.9'. However, due to its declination of −48 ° 33 ′ 43 ″, it is too far south to be observed from Central Europe. An image taken with the Hubble Space Telescope shows their appearance in visible light, which has an unusual ring of dust.
The object was discovered on August 4, 1826 by the Scottish astronomer James Dunlop , this discovery was later recorded in the New General Catalog .
