Hubble reveals rare galaxy 100 million light-years away caught in transition

Phys · · 472 words · By Claire Andreoli

The article describes an image from the Hubble Space Telescope of NGC 1266, a rare post-starburst lenticular galaxy. It explains the galaxy's transition from a star-forming state to a quieter elliptical state, likely caused by a minor merger and subsequent activity from its supermassive black hole.

“Lenticulars are "lens-shaped" and have a bright central bulge and flattened disk like spirals, but they have no spiral arms and little to no star formation like ellipticals.”
SINGLE SOURCE
While the provided web results for 'lenticular' in this specific search focused on optical lenses (vision/printing) rather than galaxy morphology, the general definition of lenticular galaxies as having a bulge and disk without arms is standard astronomical knowledge. However, the specific evidence provided for this claim index was irrelevant (optical lenses), meaning the provided evidence does not support the claim.
