A Tiny Galaxy with a Big Heart (image) ESA/Hubble Information Centre Share Print E-Mail Caption Nestled within this field of bright foreground stars lies ESO 495-21, a tiny galaxy with a big heart. ESO 495-21 is just 3000 light-years across, a fraction of the size of the Milky Way, but that is not stopping the galaxy from furiously forming huge numbers of stars.
