NGC 5335
Barred spiral galaxy NGC 5335 observed by the Hubble Space Telescope takes up the majority of the view. At its center is a milky yellow, flattened oval that extends bottom left to top. Within the oval is a bright central region that looks circular, with the very center the brightest. In the bright central region is what looks like a bar, extending from top left to bottom right. Around this is a thick swath of blue stars speckled with white regions. Multiple arms wrap up and around in a counterclockwise direction, becoming fainter the farther out they are. Both the white core and the spiral arms are intertwined with dark streaks of dust. The background of space is black. Thousands of distant galaxies in an array of colors are speckled throughout.

NGC 5335 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 4,911±20 km/s, which corresponds to a Hubble distance of 236.2 ± 16.6 Mly (72.43 ± 5.08 Mpc).[1] It was discovered as a nebula by astronomer John Herschel on 9 April 1828.[2]

Type

NGC 5335 is classified as a flocculent spiral galaxy, distinguished by scattered star-forming regions across its disk rather than well-organized spiral arms like those in the Andromeda Galaxy. A prominent bar stretches through the galactic bulge, directing gas into the interstellar medium and stimulating thereby star formation. These bars are transient features in galaxies, evolving over timescales of approximately two billion years. They are observed in about 30% of known galaxies, including our own.[3]

Supernova

One Type Ia supernova has been observed in NGC 5335 (SN 1996P, mag. 17) by Jean Mueller on 25 March 1996.[4][5]
