This crescent-shape image is the
best fit to observations of Sgr A*, the supermassive black hole at
the center of our galaxy

A supermassive black hole powers
jets of cosmic rays on either side the elliptical radio galaxy
Hercules A.

newfound large star cluster near the center of the Milky Way that
may be a breeding ground for intermediate black holes

Hubble's panchromatic vision,
stretching from ultraviolet through near-infrared wavelengths,
reveals the vibrant glow of young, blue star clusters and a glimpse
into regions normally obscured by the dust in this image taken in
July 2010 with Hubble's Wide Field Camera 3 and released on June
16, 2011. The center is home for a supermassive black hole that
ejects jets of high-speed gas into space.

This composite photo provided by
NASA shows A powerful jet from a supermassive black hole is
blasting a nearby galaxy in the system known as 3C321, according to
new results from NASA. This galactic violence, never seen before,
could have a profound effect on any planets in the path of the jet
and trigger a burst of star formation in the wake of its
destruction

This undated image provided by
the Gemini Observatory via the journal Nature shows an artist's
conception of stars moving in the central regions of a giant
elliptical galaxy that harbors a supermassive black
hole.

NASA's Spitzer Space Telescope
has imaged a coiled galaxy with an eye-like object at its center,
shown in this photograph released by NASA July 23, 2009. The
galaxy, called NGC 1097, is located 50 million light-years away. It
is spiral-shaped like our Milky Way, with long, spindly arms of
stars. The "eye" at the center of the galaxy is actually a
monstrous black hole surrounded by a ring of stars. In this
color-coded infrared view from Spitzer,
