Magnetohydrodynamics is one of the interesting sub-branch of physics, where we analyse fluid dynamics with the help of magnetic effects.
MHD is the marriage of hydrodynamics to electromagnetism.

Of nature's four fundamental forces, gravity is the most innately experienced. From their earliest self-directed moments, tiny children will marvel at how the dropped block — or, to parents' exasperation — the spilled drink falls to the floor. Gravity, we quickly come to learn, is a fact of life, inviolable and unstoppable.

Quantum entanglement is one of the most bizarre phenomena seen at very tiny, subatomic scales. When two or more particles link up in a certain way, no matter how far apart they are in space, their states remain linked. a single mathematical "container" can describe all particles simultaneously, regardless of their individual properties. This unified state would become known as quantum entanglement.

The northern lights, or the aurora borealis, are beautiful dancing waves of light that have captivated people for millennia. But for all its beauty, this spectacular light show is a rather violent event. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. These disturbances alter the trajectories of charged particles in the magnetospheric plasma.

In the first episode, we featured Prof. Debarati Chatterjee, a theoretical Astrophysicist, Associate Professor at IUCAA, and the Chairperson of LIGO-India Outreach...
Betelgeuse is classified as a red supergiant of spectral type M1-2 and is one of the largest stars visible to the naked eye. A supernova is the explosive death of a star in an event so violent that for a brief period that single star shines as brightly as a whole galaxy of more than a hundred billion ordinary stars like the Sun. This is a relatively rare event...
Extraterrestrial life/intelligent life sometimes colloquially referred to as alien life, is hypothetical life that may occur outside Earth and which did not originate on Earth. For millennia, humans have gazed in wonder at the stars, trying to understand their nature and importance...
The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. An extra dose of dark energy in the early universe, dubbed early dark energy, could reconcile the conflicting values of the Hubble constant. The outward pressure of this early dark energy would have sped up the universe’s expansion...
Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium, and lithium during the Big Bang. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support
2021 REWIND of the highlights from the field of astronomy.
Gravitational lensing: When light passes one of these objects, such as a cluster of galaxies, its path is changed slightly. This effect, called gravitational lensing, is only visible in rare cases and only the best telescopes can observe the related phenomena. Smaller objects, like individual stars, can also act as gravitational lenses when they pass in front of more distant stars...
