Variable star Mira Ceti

author: Nasa/Novapix

reference: a-eto20-00101

Image Size 300 DPI: 16 * 16 cm

Hubble's visible-light image of the disk of Mira reveals it has an odd, asymmetrical shape resembling a football. This may be tied to dramatic changes occurring during its expansion-contraction cycles, or to the presence of unresolved spots on its surface. Hubble measurements show the red giant star is 700 times larger than our Sun.
