NGC 4004 is a barred irregular galaxy in Leo, 151 million light-years away

NGC 4004 is a barred irregular galaxy in the constellation Leo, 151 million light-years away. It shines at magnitude 13.6 and spans 1.2′ × 31″ of sky, about 51,500 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in May.

Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
