Hubble records ‘blooming’ galaxy 25 million light-years from Earth

A new capture by the Hubble Space Telescope shows an irregular dwarf galaxy called NGC 1156, located 25 million light-years from Earth in the constellation Aries. In the image, speckled “red flowers” can be seen in a setting that the European Space Agency (ESA) has classified as a “galactic morphological marvel”.

This bright “garden” scattered in the photo represents areas of intense star formation, which feed the galaxy’s extreme energy. The red coloration is caused by the ejection of ionized hydrogen gas from these young stars.

“Its thousands of bright stars evoke a spiral galaxy, but it lacks the characteristic curvy structure,” reports a press release from NASA’s Hubble project partner ESA. “However, it also emits a diffuse glow, much like an elliptical galaxy and its core of older, redder stars. »

Precisely because it doesn’t fit any sort of distinct shape — neither a spiral nor an elliptical structure — astronomers classify NGC 1156 as an irregular dwarf galaxy.

However, as the website points out space.comit is also classified as isolated, as no other galaxies are located close enough to influence its odd shape and continued stellar production.

The new image was captured by Hubble under a program called All Known Neighboring Galaxies (something like “Every Known Near Galaxy”, in Portuguese), which aims to fill a gap in galactic observations.

“Astronomers have noticed that only three-quarters of galaxies just over 30 million light-years from Earth have been observed by Hubble in sufficient detail to study the composition of the stars within them,” says the ESA press release. “They proposed that between larger projects, Hubble could produce snapshots of the remnant – including NGC 1156. Infill programs like this ensure the best use is made of Hubble’s valuable observing time. »
