Comparison between a conventional galaxy (ESO 325-G004) enveloped in a halo of dark matter, occupying the heaviest plate on the weight scale, and the galaxy NGC 1277 (on the left), in which the study of the mass distribution reveals the absence of dark matter.

The puzzle of the galaxy with no dark matter

Categories Physics & Mathematics, Space

The Hubble Space Telescope has captured an image of an object in the ultraviolet part of the spectrum, which appears similar in size to our Milky Way. Researchers have been puzzled by this object for some time, but recently found similarities between it and a nearby galaxy known as IC 5249, which lacks a bulge and is observed edge-on. The images in ultraviolet and visible light of both objects are strikingly similar and suggest that the object could be a galaxy without a bulge viewed edge-on. Credit for the images goes to HST.
