最近发现椭圆星系里拥有比银河系更多的红矮星，说明宇宙里所有恒星的数量可能是原先预想的三倍。
The discovery that elliptical galaxies have many more red dwarf stars than the Milky Way means that the universe might have three times as many total stars as previously thought.

Observations by Hubble’s Advanced Camera for Surveys spotted 29 dwarf elliptical galaxies in the Perseus Cluster located 250 million light-years away and one of the closest galaxy clusters to Earth.
他们在8个的大型椭圆星系中发现了红矮星发出的微弱信号，这些星系离我们相对较近——它们的距离都在5千万到3亿光年之间。
They found faint signatures of these red dwarf stars in eight massive elliptical galaxies relatively close to us—between 50 million and 300 million light-years away.
吸收特性的力度显示，红矮星数量约占椭圆星系星量的百分之八十，质量则是那些星系总质量的百分之六十。
The strength of the absorption features indicates that red dwarfs account for 80 percent of the number of stars in elliptical galaxies and 60 percent of the total stellar mass in those galaxies.
