Explanation:

Both statements are correct.

Recently, the European Space Agency’s (ESA) Euclid space telescope has discovered a rare ring of light, known as an Einstein ring, around a galaxy nearly 590 million light-years away from Earth.

• It is a ring of light around a form of dark matter, galaxy or cluster of galaxies.

• It is essentially an example of gravitational lensing.

• Einstein rings are not visible to the naked eye, and can be observed only through space telescopes such as Euclid.

• In the case of the recently discovered Einstein ring, NGC 6505 was the gravitational lens.

• The nearer galaxy distorted and amplified the light coming from a distant unnamed galaxy, located 4.42 billion light-years away.

• These are named after mathematician and physicist Albert Einstein, whose general theory of relativity predicted that light could bend and brighten around objects across the cosmos.

• The first Einstein ring was discovered in 1987, and since then, several more have been discovered. 

Hence option 3rd is correct.
