NGC 613

A spiral galaxy’s brights and darksNGC 613 is a barred spiral galaxy about 65 million light-years away in the constellation of The Sculptor. It’s core looks bright and uniformly white in this image as a result of the combined light shining from the high concentration of stars packed into the core, but a massive black hole lurks at the center of this brilliance. Its mass is estimated at about 10 times that of the Milky Way’s supermassive black hole, and it is consuming stars, gas, and dust. As matter descends into the black hole’s, it radiates energy, but when looking at the galaxy in the optical and infrared wavelengths used to take this image, there is no trace of its dark heart.

NGC 1097

NGC 1097NGC 1097 is a barred spiral galaxy. It’s also a Seyfert galaxy. These galaxies have supermassive black holes at their centers which are surrounded by accretion discs of in-falling material. Seen in visible light, most Seyfert galaxies look like normal spiral galaxies, but when studied in other wavelengths, the luminosity of their cores is of comparable intensity to that of entire galaxies the size of the Milky Way.

Messier 77

Messier 77 (aka, M77 or NGC 1068) is a barred spiral galaxy about 47 million light-years away in the constellation Cetus. This Hubble visible light image doesn’t reveal M77’s central bar. However, infrared images of the inner part of the galaxy reveal a prominent bar feature, so it is considered a barred spiral galaxy.

Messier 95

Messier 95 (aka M95 or NGC 3351) is a barred spiral galaxy located about 33 million light-years away in the constellation Leo. It has an an inner ring that surrounds the bar. The ring is star-forming region with a diameter of approximately 2,000 light-years, and the spiral arms extend outward from the ring.

NGC 1483

ngc-1483-smallNGC 1483 us a barred spiral galaxy a bit over 60 million light-years away.  Barred spiral galaxies are so named because of the prominent bar-shaped structures found in their center. Roughly two-thirds of all spiral galaxies, including the Milky Way, are barred. It’s been suggested that bars may be a common stage in the formation of spiral galaxies and may indicate that a galaxy has reached full maturity.
