The European Space Agency published a picture of the SGAS J143845+145407 galaxy, obtained by the Hubble Space Telescope. Gravity lensing led to a mirror image of the galaxy in the center of the image, creating an exciting central element in the image.
In the center of the new Hubble image, the bright light emanating from SGAS J143845+145407 looks like an arc or ring around an object located between a distant galaxy and a space telescope. The image also shows several other galaxies and celestial objects scattered across space.
Gravity lensing is a direct consequence of the general theory of the relativity of Albert Einstein. Massive bodies distort space-time by changing the movement of light around them. This effect is particularly visible in massive objects such as clusters of galaxies. Such objects act as lenses, and a distorted background object is called "linze".
Researchers from the European Space Agency note that the Hubble telescope is very well suited to search for gravitational lenses. Supersensitive instruments and crystal clean mirrors of the space telescope allow it to see weak and remote gravitational lenses that cannot be detected by ground telescopes due to the blurry effects of the Earth's atmosphere.
Researchers use this feature of the telescope to study the galaxies of the early universe. The gravitational lens not only distorts the image as it is in a published image. Like a real optical instrument, it allows you to look at the details of distant objects from which the light has been curved by the lens.
Previously, Hytech described how astrophysicists used gravitational lensing to explore the dark matter of the early universe.
