NGC 3660 and Burçin's Galaxy
2026-05-26
The upper galaxy might be more photogenic, but the lower galaxy is more unusual. The galaxy up top is NGC 3660, a spiral galaxy similar to our own Milky Way galaxy in that it has several bright blue spiral arms and a central bar of stars, dust, and gas. Captured by chance in the featured deep and colorful image, surprisingly, is SN 2026cff, a supernova found just to the right of the central bar. Farther in the distance is the bottom galaxy, known informally as Burçin’s galaxy, but formally cataloged as LEDA 1000714. The center of this galaxy appears to be an old elliptical galaxy, but it is strangely surrounded by not one but two rings of stars. What created Burçin's galaxy is a mystery and remains a continuing topic of research, but it likely involves the accretion of one or more smaller galaxies.

638 Moira, also known as A907 JG, is a minor planet orbiting the Sun. First observed in 1906, 638 Moira was discovered to be an orbital body in 1907 by Joel Hastings Metcalf in Taunton, England. 638 Moira is a little over 59.5 km across and rotates once every 10 hours. Its farthest point from the sun is a little over 3au during its 4.5 year orbit, and it is classed as an L-type asteroid (SMASSII).
