Summary

DescriptionM33 X-7 Optical.jpg	English: The composite image includes data from NASA's Chandra X-ray Observatory (blue) and the Hubble Space Telescope. The bright objects in the inset image are young, massive stars around M33 X-7, and the bright, blue Chandra source is M33 X-7 itself. X-rays from Chandra reveals how long the black hole is eclipsed by the companion star, which indicates the size of the companion.

Image title	This artist's rendering shows a black hole in orbit with a large blue star. Material from the star is being pulled into a disk that revolves around the black hole at the center (orange disk). X-rays from Chandra and optical data from the Gemini telescope help determine that this black hole is almost 16 times the mass of the Sun. This is the highest mass ever determined for a black hole of this category. Data have also revealed that the companion star has an unusual size, containing about 70 times the Sun's mass. The inset shows a Chandra/HST composite image.
