NGC 80 is classified as a giant lenticular galaxy. Its circumnuclear ring measured 5″t 7″ in radius, is 7 billion years with an olderstellar population of 10 billion years. The galaxy also has a metal-rich chemically distinct nucleus.[6]
According to astronomers who studied the budges of seven members in the NGC 80 group in 2008 using theBTA-6 telescope, they discovered thestars have an estimated age of between 10 and 15 billion years old. However, IC 1548 (another member of the NGC 80 group) was exceptional since it showed signs of recentstar formations, with a budge and nucleus age calculated to be 3 and 1.5 billion years respectively. Moreover, IC 1548 also has a thin-like gas structure indicating itsinteraction caused it to become alenticular galaxy.[7]
The following year, the same telescope was used, this time to observe 13disk galaxies in the group. Of the 13 galaxies, 9 were lenticulars. Astronomers also found there is one case of ongoing star formation in UCM 0018+2216 and that all galaxies studied exhibited a two-layeredstellar disk brighter than M B ~ -18.[9]
