Scarlet “blossoms” of star formation stick out in a fresh image of an unconventional galaxy.

A fresh photo from the Hubble Space Telescope captures a dwarf irregular galaxy called NGC 1156. Located 25 million light-years from Earth in the constellation Aries, NGC 1156 has a unique structure unlike almost every other galaxies a “marvel of galactic morphology,” in accordance with a statement from the European Space Agency (ESA), that is a partner on the mission.

“Its a large number of bright stars evoke a spiral galaxy, nonetheless it lacks the characteristic ‘winding’ structure,” ESA officials wrote in the statement releasing the brand new Hubble image on Aug. 22. “Yet in addition, it radiates a diffuse glow, similar to an elliptical galaxy and its own core of older, redder stars.”

The shining red blossoms scattered over the photo represent regions of intense star formation, which fuels the galaxy’s extreme energy. The ionized hydrogen gas outflows from these young stars produces a red glow.

Spiral galaxies typically exhibit a central bulge comprised of older, dimmer stars surrounded by way of a flat, rotating disk of hot young stars. While NGC 1156 has a densely-packed center with older generations of stars, its younger stars aren’t within the telltale spiral arms circling the galaxy. Trained with lacks any kind of distinct shape neither a spiral nor an elliptical structure astronomers have classified NGC 1156 as a dwarf irregular galaxy.

However, the galaxy can be classified as isolated because no other galaxies can be found close enough to influence its odd shape and continuing star formation, based on the statement.

While Hubble has previously photographed NGC 1156, the brand new image was captured within an application called Every Known Nearby Galaxy, which aims to fill a gap in galactic observations.

“Astronomers pointed out that only three quarters of the galaxies in a matter of over 30 million light-years of Earth have been observed by Hubble in sufficient detail to review the makeup of the stars within them,” based on the ESA statement. “They proposed that among larger projects, Hubble could take snapshots of the rest of the quarter including NGC 1156. Gap-filling programs such as this one make sure that the very best use is constructed of Hubble’s valuable observing time.”
