A sun-like star orbiting a black hole.
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Some black holes are a result of dying stars. Because no light can escape, black holes are ...
The characteristics of the individual star and black hole system determine what kind of emission scientists observe, creating a wide array of behaviors to categorize. Previous examples include an outburst that occurred every 114 days, potentially caused by a giant star orbiting a black hole with 78 million times the Sun’s mass.A Sun-like star orbiting a boson star.

A group of physicists has developed a model that charts the unexpected orbit of a star around a supermassive black hole, uncovering new insights into one of the cosmos’ most extreme environments. Millions of light-years away in a remote galaxy, a star is being torn apart by the immense gravitational pull of a supermassive black hole.
The high-precision astrometric mission GAIA recently reported the remarkable discovery of a Sun-like star closely orbiting a dark object with a semimajor axis and period of 1.4 au and 187.8 d, respectively.

Now, they have firmed up the numbers. In order to receive strong enough CMB light, a planet would need to orbit very close to the black hole's event horizon. Normally an object that close would soon get sucked in. If the black hole is spinning fast, however, close stable orbits are possible.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes.
