✵✵✵✵✵ What are neutron stars? (Astronomy)
Stars are not eternal and unchanging - they are born, live their lives, and then die. The way a star dies depends on its mass. A low mass star ends as a white dwarf. A high mass star becomes a black hole. But in between, a star becomes a neutron star.

In this video we talk about which stars become neutron stars, and the physics behind their formation.

Y'all speak so clearly I really can't get over it. I dunno how large your team is but whoever is doing the writing and topic design deserve(s) a gold star (your presenters are great too, they speak clearly and emphatically.)

[charjl]

Eh.... I hit the subscribe button because she told me to. I thought I was stronger than that

[jakereeves]

Well, I am most entertained by this engaging presenter.

Great video, Socratica team! I remember learning in school that neutron stars are so dense that one teaspoon of neutron star material has the equivalent mass of around 900 Great Pyramids of Giza (and if my math is correct, that's over 30 million locomotives). That fact really stuck with me and was one of those mind-blowing moments in my early education that really got me interested in science! It was great meeting some of you at VidCon last week. Keep up the great work!

Dying stars can become white dwarfs, black holes or *neutron stars*.  This video talks about the formation of neutron stars and why they are sometimes called *pulsars*.

I believe the danger zone you mentioned around the 2:00 minute mark is not called the Sch. radius, but the event horizon.

The Schwarzchild radius is just the point of density of matter where the gravity becomes so strong that not even light will be able to escape the surface of said matter. In other words, it's a black hole.

An example, the Sch. radius of the earth is the size of a marble. If you crushed the entire earth into the size of a small marble, the earth will become a black hole.

Wealthy packets of lucid information delivered eloquently.

[francescomelfi]

You are amazing! Please go on with this project, especially with ASTRONOMY! The best ever!

5:10 I feel like Jocelyn Bell should have been mentionned in the video as she co-discovered the first radio pulsars in 1967

[ssacharjya]

Congratulations!! You've got one more person doing just the right thing. I subscribed for this amazing channel. Keep making more videos.

[MoreGore]

Thank you Ms. Castro, your delivery was spellbinding.

[banknot]

Charming ;>
I see there is already an astronomy playlist. I am looking forward to seeing next episodes :D

[SalvaFiorenza]

Superb explanations, an epic intro and a hilarious outro, you are amazing guys! Just gained a bunch of likes and a new subscriber!

[GearheadKC]

The "danger zone" of a black hole is not called the Schwarzschild radius. It's the event horizon. The Schwarzschild radius is simply the radius any object of matter has to be crushed down to in order to become a black hole.

LOL Couldn't help but laugh.
This is excellent quality work. If all your videos are like this, you've got a subscriber for life. Thank you so much.

Wonderful. As much as on a fundamental level this video is (it is an introduction, after all), an important comment is made which almost all other discussions about neutron stars seem to miss. That is, that not all the matter in a neutron star consists of neutrons (chargeless), but also of some protons and electrons. Combined with the huge rotation rates, THIS is what makes them have such strong magnetic fields. I believe it's important to make that distinction, as a pure ball of neutrons wouldn't have a magnetic field.

[boomcloser]

Excellent video, loved it so much! I'm looking forward for new astronomy videos! 😄

[aritcey]

Best presentation and explanation I've ever witnessed. Very informative!

[bakeryasa]

She’s speaking simple and understanding for everyone Tnx a lot Socratica👌👌

[ableg]

This channel is so nice .... I Love it!!
