NGC 613's core has a bright white appearance in this image resulting from the combined light shining from the concentration of stars within, but at the center of this shining light hides a monstrous black hole which leaves no trace in the optical and infrared wavelengths used to take this image. NGC 613 floats 65 million light-years away in the constellation of Sculptor (The Sculptor). Image released Sept. 28, 2015.

about the photos in an email message to Space.com: “They were taken during this summer near my town. This is a flat land and the light pollution is quite [powerful] so one needs to go out many times to get ‘the’ shot…. The last two pictures ... had been taken in July about one week [before] I went for a deployment. Me and my loved one went out together which is a big deal because usually I go out alone. So we took some pictures together. As I am now stationed next to a capital I do not have a chance to see the starry ‘face’ of the night sky for months. So these pics were my goodbye shots both to my spouse and the night sky for a while.”

of the Chilean Atacama Desert. The moon shines overhead while the sun has set below the horizon at left. The telescope’s metallic dome prevents the enclosure from daytime warming, which produces warm air and turbulence that damage the condition for astronomical seeing. The designers of the facility have even painted the concrete platforms and parking spaces white to increase the amount of light reflected from their surfaces. Image released Sept. 21, 2015.

dust and gas occuring throughout its disc. The galaxy falls into the class of flocculent spirals, which lack arms with sharply defined structure unlike grand design spirals such as Messier 101. About 30 percent of galaxies possess patchiness like NGC 3521, while approximately 10 percent have the shape of grand design spirals. NGC 3521 lies almost 40 million light-years away in the constellation of Leo (The Lion). Image released Sept. 21, 2015.

The spiral arms of the Messier 63 resemble a sunflower, giving rise to the nickname "Sunflower Galaxy."

Muckenhuber writes in an email message to Space.com: “I took this picture from a quite dark spot in … Tirol. I collected 16 hours of data and it also took me about 20 hours of processing until I was satisfied with the result. The exposure of 16 hours was necessary to bring out the faint Integrated Flux Nebula (IFN) … “ appearing as the gray dust in the image. He notes the IFN, which lies closer to us than the two galaxies, is made visible by the glow of stars in our Milky Way.

has a mass and size similar to the Milky Way. Messier 96 possesses a very asymmetric shape, with its dust and gas spread unevenly throughout its weak spiral arms, and a core that does not sit exactly at the galactic center. Its arms also show asymmetry, and they may have been pulled by the gravitational pull of other galaxies within the same group as Messier 96.
