The NASA/ESA Hubble Space Telescope has captured a striking photo of the lenticular galaxy NGC 4036.
This Hubble image shows the lenticular galaxy NGC 4036. The bright star visible slightly to the right of the galactic center is not within the galaxy itself; it sits between us and NGC 4036, adding a burst of brightness to the scene. The image is a composite of separate exposures acquired by Hubble’s Advanced Camera for Surveys (ACS) instrument. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / Judy Schmidt, www.geckzilla.com.
NGC 4036, also known as LEDA 37930, UGC 7005 and IRAS 11588+6210, is classified as an early lenticular galaxy.
It lies in the constellation Ursa Major, approximately 80.2 million light-years away.
This galaxy belongs to the LGG 266 galaxy group, along with NGC 4041, IC 758, UGC 7009, and UGC 7019.
NGC 4036 is known for its irregular lanes of dust, which form a swirling spiral pattern around the center of the galaxy.
This core is surrounded by an extended, hazy aura of gas and dust that stretches further out into space and causes the warm, fuzzy glow that can be seen here.
The center itself is also intriguing; it is something known as a LINER-type (Low-Ionisation Nuclear Emission-line Region) galactic nucleus, meaning that it displays particular emission lines within its spectrum.
On July 23, 2007, a supernova called SN 2007gi was observed by Japanese amateur astronomer Koichi Itagaki near NGC 4036’s central bulge.
This Type Ia supernova reached peak magnitude around August 14, then steadily declined in brightness thereafter.
Materials identified in the SN 2007gi spectrum included silicon, calcium, and sulfur moving outward at velocities of around 33.6 million mph (15,500 km/s) — this is a 50% higher velocity than what is normally observed in Type Ia supernovae.
