Hungarian mirror?  Stunning view captured by the Hubble Space Telescope

Hungarian mirror? Stunning view captured by the Hubble Space Telescope

Recently, nearly all of the astronomical glory has fallen on the James Webb Space Telescope, but a true veteran of the field – the Hubble Space Telescope – cannot be forgotten.

This time it was due to the image showing SGAS J143845 + 145407. Contrary to appearances, these two galaxies are not identical, but rather one. The mirror image effect that we can observe in the image below is the gravitational lensing effects.

This phenomenon occurs when there is another massive structure between the observer and the object (in this case, the galaxy SGAS J143845 + 145407). The effect of gravity on the light emitted by the object in question causes the image to enlarge and bend. Contrary to appearances, such an effect is very useful for astronomers and is often used to observe distant regions of the universe.

The Hubble Space Telescope has been observing space for more than thirty years

It took about 6.9 billion years for light from SGAS J143845 + 145407 to reach Earth. In contrast, a small group of galaxies that get in the way and sway them with their own gravity are a little closer. Its light only took 2.8 billion years to reach our planet. The interactions caused by the phenomenon of gravitational reversal made the galaxy visible as in an inverted image.

A key aspect of this is the expanded and more detailed view of SGAS J143845 + 145407. This galaxy is visible in infrared light and shines relatively brightly, reflecting the intense formation of young stars in this region. By making more observations, scientists should be able to better understand this process, especially considering the distant times when the sun has not yet formed. Of course, the most detailed data should come from the more advanced James Webb Space Telescope, which recently began its mission.
