The universe is full of galaxies and our eye cannot see all of them. The Hubble telescope discovered a beautiful galaxy cluster and the cluster is named as SDSS J0146-0929. This is the collection of the hundreds of galaxies which are shackled together in a tight grip of gravity. When the Hubble Space Telescope click the the mass of the galaxy, it is very large and it can severely distort the space-time around it which create a odd, looping curves which is almost encircle the center of the cluster.
The center of the cluster is called as gravitational lensing and is known as “Einstein ring.” This ring is created from the light which comes from the distant objects like galaxies which get pass by an extremely large mass like galaxy cluster. When this light pass an extremely dense object with powerful gravitational pull then the object can disrupt the path of the light it takes to reach its destination. This prevent the light from moving in a straight line. This is called as gravitational lensing and this is the basic concept of the phenomenon.
When this phenomenon happens then it is observed to outside that galaxy is in several places at once and the edge of the Einstein ring reveals several stretch out copies of a single galaxy. But in reality, the galaxy is not present in several places but it is the distorted light which make us to see several galaxy.
The gravitational lensing is seen before many times and this is one of the less imposing instance. The other Einstein ring which is intimidating is the vaguely resembles the Eye of Sauron from Lord of rings. The Hubble Space Telescope helps us to discovered a beautiful galactic optical illusion phenomenon which is like God-like fantasy super villain.
