Earth Sized Planets

September 29, 2022 09:48 - 8 minutes - 15.5 MB

Discovering the first true "alien Earth" is a long-held dream of astronomers — and recent exoplanet discoveries have shown that small, rocky worlds like our own are abundant in the galaxy. Let’s look at some of the closest known analogues to our home planet. --- Support this podcast: https://podcasters.spotify.com/pod/show/rohit-agrawal92/support

Comet

July 16, 2022 12:19 - 9 minutes - 18.1 MB

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

February 28, 2022 13:30 - 7 minutes - 7.19 MB

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

Aurora

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

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, an...

Expansion of the universe.

January 24, 2022 13:30 - 9 minutes - 9.19 MB

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://podcas...

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.sp...
