The Life Cycle of a Star | Event Horizon | Hawking's Radiation | ForumIAS
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. This stage is known as the 'main sequence'. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.
In This Video, we will discuss:
1. About the Formation of star
2. About Protostar
3. Main sequence star
4. Giant dwarf- Neutron star
5. Black hole

Literally I m saying kuchh nahi samjha
These videos are so good. And I am amazed at the knowledge level of Ms. Vishakha. She has explained broad range of topics spanning across IR , Economics and Science. Thanks. If only I was aware of these videos a bit earlier it would have been good.
Tug of war between gravity n nuclear fusion... ma'am have you done your graduation in physics?
Nuclear fusion not fission
Not fission, fusion
I will Make all the remaining 60 days as an ideal for prelims 2024
Good effort but quite confusing for non science background but I work on myself
On the same topic, UPSC asked question in UPSC_PYQ_2023 Prelims...
Nice explnation
Upto 1.44 times the mass of sun the star is going to form white dwarf...more than 1.44 and less than 3 will form neutron stars or pulsars...and more than 3 times solar mass stars will eventually be black holes from neutron stars...
One of the best explanations on this topic on youtube. Thank you maam ❤
What an explanation mam 👏🏻 really solved my most of the doubts 👏🏻
Best explaination on youtube
Thank you so much ma'am
You are too good a teacher! All the best!
