M87 in 60 Seconds

Narrator (Megan Watzke, CXC): M87 is a giant elliptical galaxy. At a distance of about

60 million light-years from Earth, M87 is the largest galaxy in the Virgo cluster of

some 2,000 galaxies. Bright jets moving at close to the speed of light are seen at nearly

all wavelengths, powered by the supermassive black hole at the center of the galaxy. In

X-rays, M87 shows evidence for a series of outbursts from the black hole. These outbursts

appear as loops and bubbles in the data from the Chandra X-ray Observatory. The Hubble

Space Telescope shows that the monstrous elliptical galaxy is also home to trillions of stars

and thousands of globular clusters. Because of its proximity and brightness, as well as

its intriguing properties, M87 is one of the most popular targets for amateur and professional

astronomers alike.
