Astronomers utilizing the NASA/ESA Hubble Space Telescope have actually produced a lovely picture of the disallowed spiral nebula UGC 11861.

UGC 11861 depends on the northern constellation of Cepheus, roughly 69 million light-years away.

Otherwise referred to as LEDA 67671, IRAS 21557 +7301 or TC 609, the galaxy is categorized as a disallowed spiral nebula and a prospect active galactic nucleus.

UGC 11861 is made up of a rapid disk, a main blocky structure and 2 broad spiral arms.

“Among the cloudy gases and the dark wisps of dust, this galaxy is actively forming brand-new stars, noticeable in the radiant blue spots in its external arms,” the Hubble astronomers composed in a declaration.

“This activity has actually led to 3 supernova surges being identified in and neighboring UGC 11861, in 1995, 1997 and 2011.”

“The earlier 2 were both Type II supernovae, a kind which arises from the collapse of an enormous star at the end of its life.”

“This Hubble image was made from information gathered to study Type II supernovae and their environments.”

The color picture of UGC 11861 was made from different direct exposures taken in the noticeable and near-infrared areas of the spectrum with Hubble’s Advanced Camera for Surveys (ACS).

2 filters were utilized to sample different wavelengths. The color arises from appointing various shades to each monochromatic image related to a specific filter.

“UGC 11861 lies 69 million light-years far from Earth– which might appear a huge range, however it’s perfect for Hubble to get this magnificent shot of the galaxy’s spiral arms and the brief however vibrantly radiant bar in its center,” the astronomers composed.
