The Physics of Gravitational Lens
Gravitational Lensing is an interesting phenomenon that takes place due to the bending of light rays from a distant source due to massive galaxies and galactic clusters. Such galactic clusters acts as a lens, distorting, magnifying, various background objects as observed from Earth.
In this video I talk about the General theory of relativity, Gravitational lens, Einstein rings, Einstein cross and various applications in astronomy and astrophysics because of gravitational lensing.

Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies
Gravitational lensing occurs when a huge amount of matter, like a star, galaxy, or cluster of galaxies, creates a powerful gravitational field around it, strong enough to bend the light coming from distant galaxies (behind them). Roots of gravitational lensing lie in Einstein theory of relativity which states that massive bodies warp the space around it. Thereby the light passing through this warped space curves near massive celestial bodies. Depending upon the position of emitting, lensing and observing body, gravitational lensing may distort, magnify or lead to multiple occurrences of the same object in different places.
Leveraging the concept of gravitational lensing, a technique called microlensing is developed which is helping us in discovering new galaxies and dark matter. Einstein...

The Solar Gravitational Lens will Map Exoplanets. Seriously.
The Solar Gravitational Lens will Map Exoplanets. Seriously, there's a real plan to do just that. Using the Sun to gravitationally lens an exoplanet into an Einstein ring turns the Sun into the most powerful telescope in our solar system. But it's not science fiction. Plans are underway at NASA's Jet Propulsion Laboratory to send solar sails to the solar gravitational lens focus to make the first ever image of an exoplanet's surface, and do it within our lifetime!

Strong Gravitational lensing
Objects with large masses such as galaxies or clusters of galaxies warp the spacetime surrounding them in such a way that they can create multiple images of background objects. This effect is called strong gravitational lensing.

How are Distant Galaxies Magnified Through Gravitational Lensing?
How can scientists study galaxies so far away that they’re beyond the reach of the most powerful space telescopes? They take advantage of natural cosmic telescopes called gravitational lenses, illustrated in this new video.
Using the Webb telescope like a time machine, astronomers will peer back billions of years to study how stars like our Sun formed in the early universe. Astronomers will examine the lensed, magnified light from very distant galaxies that are at or near the peak of star formation. Learn how: https://go.nasa.gov/2zdvGKm

Einstein ring is a beautiful phenomena observed using microlensing which we have illustrated in this video using animations. Thus, Einstein's ground-breaking work on general relativity in 1915 has paved the way for astronomers to continue studying the very structure of the Universe leveraging the power of gravity!

Objects with large masses such as galaxies or clusters of galaxies warp the spacetime surrounding them in such a way that they can create multiple images of background objects. This effect is called strong gravitational lensing.

How can scientists study galaxies so far away that they’re beyond the reach of the most powerful space telescopes? They take advantage of natural cosmic telescopes called gravitational lenses, illustrated in this new video.
Using the Webb telescope like a time machine, astronomers will peer back billions of years to study how stars like our Sun formed in the early universe. Astronomers will examine the lensed, magnified light from very distant galaxies that are at or near the peak of star formation. Learn how: https://go.nasa.gov/2zdvGKm
