Galaxy NGC 5866 lies 44 million light-years from Earth and has a diameter of roughly 60,000 light-years - a little more than half the diameter of our own Milky Way galaxy. From our viewpoint, NGC 5866 is oriented almost exactly edge-on, yielding most of its structural features invisible.

ALMA has made the most precise measurements of cold gas swirling around a supermassive black hole -- the cosmic behemoth at the center of the giant elliptical galaxy NGC 3258. The multi-color ellipse reflects the motion of the gas orbiting the black hole, with blue indicating motion toward us and red motion away from us. The inset box represents how the orbital velocity changes with distance from the black hole. The material was found to rotate faster the closer in the astronomers observed to the black hole, enabling them to accurately calculate its mass: a whopping 2.25 billion times the mass of our Sun.

Earth’s magnetic bubble, called the magnetosphere, is illustrated in blue. The magnetosphere provides natural protection against space radiation, deflecting most charged solar particles from Earth.
