Galactic magnetic fields, they suggest, are produced by a ring of electrically charged gas rotating around
a giant black hole at the center of a galaxy.

Powerful radio jets from the supermassive
black hole at the

galaxy are creating
giant radio bubbles (blue) in the ionized gas surrounding the
galaxy.
Today, astronomers know that virtually every
galaxy harbors a
giant black hole at its
center, shaping the formation
of millions
of stars and even neighboring
galaxies with its immense gravitational influence.
Researchers will use it to study the flashes
of light given out when
black holes, including the
giant ones
at the

Last year,
at the
center of a
galaxy far, far away, astronomers watched a star send out a distress flare when a

of the
giant black hole at the
center of our Milky Way Galaxy, imaged the four massive planets orbiting the star HR8799, discovered new supernovae in distant
galaxies, and identified the specific stars that were their progenitors.

From supermassive
black holes at galactic
centers to
giant bursts
of star formation to titanic collisions between
galaxies, these discoveries allow astronomers to probe the current properties
of galaxies as well as examine how they formed and developed.
