Not one galaxy but two, locked in a gravitational embrace. Encounters like this shred spiral arms and trigger furious bursts of star formation.
Look for NGC 5421 in the constellation CVn. At apparent magnitude 14.3, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, NGC 5421 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
NGC 5421 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Galaxy, Interacting galaxy pair and Faint fuzzy (mag > 13) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
