Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of miles. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

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. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

The northern lights, or the aurora borealis, are beautiful dancing waves of light that have captivated people for millennia.

In our "Hello, Astrophysicist!" segment, we interact with some of the finest Astrophysicists and talk about lots of exciting and informative stuff. In the first episode, we featured Prof. Debarati Chatterjee, a theoretical Astrophysicist, Associate Professor at IUCAA, and the Chairperson of LIGO-India Outreach. Her research focuses on Compact Objects, specifically Neutron Stars, and she tries to understand the mysterious behavior of these celestial objects that are a source of Gravitational Waves. In this episode, we had a chat about her research, early Life, challenges she had to face as a woman in STEM, and lots of other science stuff.

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.  When this happens, Betelgeuse will brighten enormously for a few weeks or months, perhaps becoming as bright as the full moon, and be visible in broad daylight. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

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. --- 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. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

For thousands of years, humans have been trying to figure out the universe and determine its true extent. And there have been a lot of assumptions and theories. during the 1960s, astronomers became aware of microwave background radiation that was detectable in all directions. Known as the Cosmic Microwave Background (CMB), the existence of this radiation has helped to hone our understanding of how the Universe began. The cosmic microwave background (CMB, CMBR) is faint electromagnetic radiation that is a remnant from an early stage of the universe, filling all space. It represents the heat leftover from the Big Bang and radiation is most visible in the microwave part of the electromagnetic spectrum hence the name CMB. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

Something really significant for the field of astronomy was announced last week on december 14th. For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there. The new milestone marks one major step for Parker Solar Probe and one giant leap for solar science. NASA's historic Parker Solar Probe mission is revolutionizing our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. Parker Solar Probe travels through the Sun’s atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions to provide humanity with the closest-ever observations of a star. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support
