Classified as an unbarred flocculent spiral galaxy NGC 2841 lies 46 million light years away in the constellation of Ursa Major. Larger than our own Milky Way it has a diameter of over 150,000 light years. Flocculent spirals feature short spiral arms rather than prominent and well-defined galactic limbs. These arms contain many star clusters with large populations of young blue stars with whitish middle-aged stars present. Spiraling outward from the center are dark dust lanes that are silhouetted against the arms. This galaxy has had a history of supernovae explosions within it, the most recent going off in 1999.
