    Very distant galaxies are not so easy to see and sometimes the images obtained can really surprise with their unusualness.

    The Hubble Space Telescope was able to do this take a picture of a very distant galaxy that looks like two objects are visible in the image. But in reality it is a mirror image of the same galaxy. And this is the result of space-time curvature due to gravitational lensing, according to Inverse.

    A new image from the Hubble Space Telescope shows two identical galaxies in the center, tinted orange and connected by a filament. But in fact, this is one galaxy and its mirror image. This galaxy is called SGAS J143845+145407 and is 6.9 billion light-years away.

    These objects are incredibly hard to see because their light is too dim even for powerful space telescopes like Hubble. Therefore, scientists use the method of gravitational lensing to see such distant objects.

    SGAS J143845+145407 is an infrared galaxy whose light comes mainly from a large number of star-forming regions. Thanks to such galaxies, astronomers can get an idea of ​​the formation of stars and how their evolution has changed over billions of years.

    The method of gravitational lensing is that such distant galaxies can be seen using a cluster of galaxies that is located between the telescope and the observed object. This cluster of galaxies, which acts as a magnifying lens, is located at a distance of 2.8 billion years from us.

    The mass of this cluster of galaxies warps space-time and causes the light from the observed galaxy to change its path around the cluster. Sometimes this results in the image of the background galaxy that astronomers want to have a mirror image, as in this case, or the galaxy will appear as an arc or ring. The thread that connects the two galaxies is another distorted image of SGAS J143845+145407.

    It is thanks to gravitational lensing that astronomers can look into the most distant corners of our universe. Although this function has already been almost completely taken over by the new Webb Space Telescope, which began its full-fledged scientific activity on July 12 this year.

<p>The Hubble Space Telescope was the first telescope to be able to capture distant galaxies with sufficiently high detail using gravitational lensing. But the Webb telescope has more opportunities for detailing such objects, so astronomers have high hopes for it.</p>
<p>What role is assigned to the Hubble Space Telescope after the commissioning of the Webb telescope, <em>Focus</em> already wrote. We are not talking about the fact that this telescope will finish its work. It will be a reliable assistant to the new observatory.</p>
<p>By the way, the new space telescope, which will be launched in 2026 and which bears the name of one of the women leaders of NASA, Nancy Roman, will continue the work of Hubble.</p>
