NGC 7049 is a lenticular galaxy [1] that spans about 150,000 light-years and lies about 100 million light-years away from Earth [2] in the inconspicuous southern constellation of Indus.
NGC 7049's unusual appearance is largely due to a prominent rope-like dust ring which stands out against the starlight behind it. These dust lanes are usually seen in young galaxies with active star-forming regions. NGC 7049 shows the features of both an elliptical galaxy and a spiral galaxy, and has relatively few globular clusters, indicative of its status as a lenticular type. [4] [ citation needed ] NGC 7049 is the brightest (BCG) of the Indus triplet of galaxies (NGC 7029, NGC 7041, NGC 7049), [5] and its structure might have arisen from several recent galaxy collisions. Typical BCGs are some of the oldest and most massive galaxies. [6] [ dubious – discuss ]
