NGC 7582 is a barred spiral galaxy (SBab) in Grus, 70 million light-years away
NGC 7582 (ESO 291-016, PGC 71001) is a barred spiral galaxy (SBab) in the constellation Grus, 70 million light-years away. It shines at magnitude 11.0 and spans 7′ × 3.2′ of sky, about 143,600 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in October.
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.
Finding NGC 7582 from Tiaki
NGC 7582 lies 7.8° northeast of Tiaki, the magnitude 2.1 star. Three fingers held at arm's length cover about 5°.
NGC 7582 is highest in the evening in October
The chart gives its height above the horizon at 9 pm through the year, from 60°N to 40°S. It can be seen from the whole southern hemisphere and north to about 48°N, and never sets south of 48°S.
