The Hubble Space Telescope took a stunning photo of a strangely shaped galaxy

Bright red “flowers” of star formation stand out in a new image of an unconventional galaxy.

A new image from the Hubble Space Telescope shows a dwarf irregular galaxy called NGC 1156. Located 25 million light-years from Earth in the constellation Aries, NGC 1156 boasts a unique structure unlike most other galaxies – a “marvel of galactic morphology.” to the statement of the European Space Agency (ESA), which is a partner in the mission.

“Thousands of bright stars resemble a spiral galaxy, but it lacks the characteristic ‘tortuous’ structure,” ESA officials wrote in a statement releasing the new Hubble image on August 8. 22. “However, it also emits a diffuse glow very similar to an elliptical galaxy whose core is composed of older, redder stars.”

The glowing red flowers scattered across the photograph represent regions of intense star formation that are fueling the galaxy’s extreme energy. The ionized hydrogen gas escaping from these young stars emits a red glow.

Spiral galaxies typically have a central bulge of older, fainter stars surrounded by a flat rotating disk of hot young stars. While NGC 1156 has a densely packed center of older generations of stars, its younger stars do not form part of the control spiral arms surrounding the galaxy. Given the lack of any distinct shape – neither a spiral nor an elliptical structure – astronomers have classified NGC 1156 as a dwarf irregular galaxy.

However, according to the statement, the galaxy is also classified as isolated because no other galaxies are close enough to affect its strange shape and ongoing star formation.

While Hubble previously photographed NGC 1156, the new image was taken as part of a program called Every Known Nearby Galaxy, which aims to fill a gap in galactic observations.

“Astronomers observed that only three-quarters of the galaxies within just over 30 million light-years of Earth have been studied by Hubble in sufficient detail to study the composition of the stars within them,” the ESA said in a statement. “They proposed that, in between larger projects, Hubble could take pictures of the remaining quarter, including NGC 1156. Gap-filling programs like this ensure that Hubble’s valuable observing time is put to the best use.”
