As the distance between the telescope and Earth increases, it allows astronomers to see an object in space from two different perspectives, just like our poor pair which give us a deeper look

An original idea allows the Spitzer Space Telescope to calculate the distance between distant objects in space, and to confirm their belonging to the Milky Way. It is more intriguing to know that these objects are a pair of black holes that orbit each other, undoubtedly a rare sight.
The Spitzer Space Telescope is the only telescope that orbits the Sun behind the Earth's orbit. Spitzer is 70 million km away from us, and it continues to advance every year by about 15 million additional km.
As the distance between the telescope and Earth increases, it allows astronomers to see an object in space from two different viewpoints, just like our poor pair which give us a deeper view, so that two telescopic viewpoints can calculate the distance to the same object in space.
Astronomers noticed that something was making the star brighter. The speed and intensity of that brightness corresponds to the phenomenon of gravitational dimming, where the object's gravitational foreground is focused by the light of a more distant star. They described the event from Earth, but also took advantage of Spitzer's presence for a cross-view. The data that came from both places were combined and presented a firm conclusion, the bone was found in the milky way.
The distortion of light created as a result of gravitational mixing led the researchers to believe that they were looking at two objects orbiting each other, most likely a pair of black holes, but there is also the possibility that these are two neighboring stars orbiting around the same center of gravity.
(Translator's note - Gravitational obsolescence is a phenomenon in which gravitation from a very massive object bends the light rays, in a manner similar to a lens. As a result, the path of the light from the source is curved, and a distorted image is obtained. The phenomenon of gravitational obsolescence is a prediction of the general theory of relativity developed by Albert Einstein and was one The first tests for confirmation. Today, this phenomenon finds great use in astronomy as a tool to make observations and study the universe-Wikipedia source.)
