BLACK HOLES A black hole is a place in space where the force of gravity is so strong that nothing, no light, no matter, no energy can escape. The reason for this is that space and time are warped by the strong gravity. The above image is of Cygnus X-1, the first black hole identified using X-ray observations. This black hole is about 14.8 times the mass of the Sun, and the star orbiting it is about 18 times the mass of the Sun. It is about 6,000 light years from Earth. The above image is of the black hole at the center of the Messier 87 galaxy, 55 million light years from Earth. It is about 6.5 billion times the mass of the Sun, and has an event horizon of about 22 billion kilometers, or 140 million times the diameter of the Earth's orbit. The above image is of the black hole at the center of the Milky Way galaxy, 26,000 light years from Earth. It is about 4 million times the mass of the Sun, and has an event horizon of about 44 million kilometers, or 290 times the diameter of the Earth's orbit. The above image is of the black hole at the center of the IC 1101 galaxy, 1 billion light years from Earth. It is about 100 trillion times the mass of the Sun, and has an event horizon of about 624 million kilometers, or 4.2 million times the diameter of the Earth's orbit. The black hole at the center of the universe is about 10 to the power of 50 times the mass of the Sun, and has an event horizon of about 10 to the power of 26 kilometers.
