BY
ALL OUTWARD APPEARANCES, our galaxy,
the Milky Way, may seem reliably
stable. In fact, the universe is in constant
flux, according to U.Va. student Rachael
Beaton, who says that, because the
timescale for change beyond the orbits
in our solar system is so long, it appears
that very little occurs in one
lifetime. But even the largest
structures are constantly evolving.
Beaton is part of a research team at
the University
that is studying Andromeda, the nearest
spiral to ours, in hope of unlocking
the mysteries of the Milky Way’s “wild
past” and unpredictable future. Full
story.
