NASA’s Hubble Space Telescope captured a new image of NGC 1827, an edge-on spiral galaxy 37 million light-years away in Columba, part of a survey to study low-mass galaxies and refine cosmological models.
The Hubble Space Telescope has revealed a detailed image of NGC 1827, an intermediate spiral galaxy located approximately 37 million light-years from Earth in the southern constellation Columba. The galaxy, first discovered by British astronomer John Herschel on November 28, 1837, was observed as part of a survey examining 260 satellite galaxies orbiting 22 Milky Way-like host galaxies within 32 million light-years of Earth SCI. Otherwise known as ESO 362-6, LEDA 16849, or IRAS 05083-3701, NGC 1827 belongs to the NGC 1792/1808 group of galaxies SCI.
Highlights Bright-Blue Regions in NGC 1827 Disk
The image, taken with Hubble’s Advanced Camera for Surveys (ACS), highlights bright-blue regions along NGC 1827’s disk, dotted with dark dust lanes where new stars are likely forming. A foreground star, closer to Earth than the galaxy, appears to the left of the galaxy’s central bulge, its four diffraction spikes caused by light bending around Hubble’s secondary mirror NASA. The survey has already observed 111 of the 260 target galaxies, with 149 remaining to be studied over the next 149 Hubble orbits.

The image was captured as part of a research project examining 260 satellite galaxies orbiting 22 Milky Way-like galaxies. They are located within a radius of about 32 million light-years from Earth. Hubble has already studied 111 of these galaxies. Observing the rest will require another 149 orbits of the telescope around Earth – one for each galaxy .
Scientific Purpose and Implications
Galaxies with low mass, such as those included in this Hubble observation initiative, offer a method to evaluate the predictions of cosmological models at smaller scales, which are challenging to align with observations.
