"I suddenly feel very crowded. The cool dwarf stars have been undercounted. They've been staying in the background trying to avoid being noticed..
The biggest galaxies in the universe are elliptical galaxies. The largest of these hold over one trillion stars according to astronomical census takers, compared to 400 billion in our Milky Way. However, new research shows that elliptical galaxies actually hold five to ten times as many stars as previously believed. This means that the total number of stars in the universe is likely three times bigger than realized.
As soon as the news about these dwarf stars gets spread across the galaxies residents of their habital planets are going to be at much greater risk of interstellar invasions."
