DEEPEST VIEW OF SPACE YIELDS YOUNG STARS IN ANDROMEDA HALO

Relying on the deepest visible-light images ever taken in space,
astronomers using NASA's Hubble Space Telescope (HST) have reliably
measured the age of the spherical halo of stars surrounding the
neighboring Andromeda galaxy (M31).

To their surprise, they have discovered that approximately one-third of
the stars in Andromeda's halo formed only 6 to 8 billion years ago.
That's a far cry from the 11-to-13-billion-year age of the stars in the
Milky Way's halo.

Space Telescope is a project of international cooperation between NASA
and the European Space Agency (ESA).
