Centaurus A
Explanation: Only 11 million light-years away,
Centaurus A is the closest
active galaxy to planet Earth. Spanning over 60,000 light-years, the peculiar elliptical galaxy also known
as NGC 5128, is featured in
this sharp telescopic view.
Centaurus A is apparently the result of a
collision of two otherwise normal galaxies resulting in a fantastic jumble of star clusters and imposing dark dust lanes. Near the
galaxy's center, left over cosmic debris is steadily being consumed by a central black hole with a billion times the mass of the Sun.
As in other active galaxies, that process likely generates the radio, X-ray, and gamma-ray energy radiated by
Centaurus A.
