Hubble telescope shows image of odd mirrored galaxy!
Recommended for Exploration
Recently, the Hubble space telescope has recently revealed a strange image of a mirrored galaxy. In the image, we can see two mirrored galaxies and it showed orange-coloured galaxies connected by a long filament.
It’s not two galaxies, but one galaxy named SGAS J143845+145407. It appears to be two galaxies due to the gravity of the objects. The quirk of gravity can be used to magnify the light of background galaxies and it would be distant as shown in the image.
Details of the mirror galaxy SGAS J143845+145407
The galaxy SGAS J143845+145407 appears behind a small galaxy cluster for gravitational lensing to produce nearly perfect images of the galaxy. The light from the galaxy travels around 6.9 billion years to reach us. That is about the current age of the universe.
The galaxy SGASJ143845+145407 is interesting because the galaxy is a luminous infrared galaxy and it glows brightly due to the activity of star formation. Studying galaxies can help scientists to understand star formation and how the universe has changed. Gravitational lenses are important for such works.
What is gravitational lens?
A gravitational lens is a distribution of matter between a distant light source and an observer that is capable of bending the light from the sources the light travels towards the observer.
Using the gravitational lens, scientists were able to reconstruct the distribution of star formation in SGAS J143845+145407 and studied the details of the process.
The Hubble space telescope has revolutionized the study of lensed galaxies. The observations by the Hubble telescope were the first to resolve details inside lensed galaxies and gave scientists an incredible new window into the early universe.
James Webb’s telescope is expected to reveal even more details. These odd images are lensed galaxies. Scientists are studying to learn more about lensed galaxies.
