People often ask: "how big is the biggest star?" But I reckon the more interesting question is how small are the smallest stars? Because when you get down to the smallest stars, there's a huge grey area between what is a star and what is a planet. Sub-brown dwarfs, planemos, rogue planets - how do we actually tell them apart?

Your series should be required viewing in every grade school in the world 'til every little girl understands she doesn't need to give up anything to be a scientist. Black holes+girlish giggles; neutron stars+ killer nails; "cute" planemos + "look at my earrings". This is what girls need to see before the world convinces them it's not feminine to be smart or educated or scientifically literate. Although the other young, female science presenters are very good, you are special. YOU are what they need to see 'till the day comes when it is normal for any little girl to carry a doll in one arm and a science text in the other. We are going to need every single one of you we can find.

The world does not convince women it's not feminine to be smart or scientifically literate. Being versed in Astrophysics, the science of parroting information does not directly correlate to being intelligent. The study and knowledge of a subject or subjects......obviously requires some level of intelligence although it's very possible to have such qualifications using commitment and a well exercised memory. The foundation of science is to question everything but let's just force cram space 'facts' on them because we 'Need' equal amounts of women in every field and those that aren't, are not as useful in future society.......we need every one we can get! Mankind is struggling without more women in SCIENCE! The thing is, there will never be as many women in certain fields, and vice versa. But there is absolutely nothing wrong with that, and it is not just societal pressures but also a natural tendancy toward gaining certain skills ie to attract a mate. There's nothing wrong with being whatever the heck they want and I don't feel like the world (Well at least western world) has done anything but support women and men to have the option to do anything they want to follow, maybe........just maybe women generally don't see a value in the theoretical science fiction of astrophysics. I'm all for everyone chasing their dreams but forced (equality? - As seen in some workplaces with men/women numbers etc prioritised over actual talent or productiveness) is plain ridiculous and not freedom or liberating anyone of the societal pressures in my opinion. Plus your whole post is full of stereotyping........dolls......giggling......which is the problem with society not letting women become scientists right?

@@snitchcore8635 Your problem is your ignoring the social pressures like your not feminine if you do a set activity. Women on a steady basis report on the social pressure that causes them to avoid certain things only once we eliminate these social pressures will we be able to tell what if any biological causes are involved. I agree with you it not helpful to quota improve a work force. But as discrimination did exist and still shows up when you test for it special efforts to train oppressed groups to meet the same standards as white males are still needed. And all jobs must set measurable standards for jobs so that the biased discriminating choice of the boss keeps less qualified white males as perjured. No the point is stereotyping girls who are into girl stuff can't be brilliant scientists causes many of these girls to avoid science. The original point of Dennis Best is anti stereotyping by people telling girls they can't be girly and into science is the problem to be fought. With the massive discrimination in the past and lawsuits still frequently finding irrational discrimination against women it is way to soon to be assuming current behavior in females is purely genetically based. But back on your side of the argument as before refrigeration, when males were expendable and females were not for making a new generation, when females often were taken by other tribes, when females had to have as many children as possible and thus start at puberty whatever age that occurred (12 in ancient world was norm but early developing girls were married younger, with modern life girls hit puberty more at 10) And thus female were always nursing or pregnant it made sense to have them do the work needed in camp and care for young children. So dolls are a primary female instinct and thus the vast majority of doll users will be female, but like any instinct some boys have that instinct and should be allowed to be into it. And a complete matriarchy was formed under the restrictions I just mentioned and this matriarchy still exist today. And many tribes had women warrior who often were as good or better in combat as clearly martial arts development allowed some women to use their physical flexibility and endurance advantages to over come the male advantage in dumb brute violence. After all the best male warriors oftener were not the biggest and strongest male so you can see how women at the top of the female bell curve could beat men for the same reasons the smaller weaker man was beating the stronger bigger men. The need for reproduction though did limit the woman warrior to a small part of the forces. Societies that did not allow women warriors strangely often put aside a similar number of women in chaste things like nuns.

​@@snitchcore8635 I think the core of the post was "representation matters", and, if you're going to get all pseudo-intellectual and preach about what science is, you may be interested in Googling any of the MANY studies that demonstrate that society does actively and passively discourage girls from entering STEM. Women have been in STEM since day one, despite being actively discouraged and erased. Without women, we wouldn't have a lot of the knowledge we do now. I mean, equations that are the foundation of physics, for example. Just think of how much better off we'd be if MORE women were encouraged to join STEM (do not combat this with "encourage boys to do STEM, too!" everyone should, but boys are not actively told not to, are not sexually harassed to the point of dropping their career, are not brought to a prestigious conference as presenters only to be followed by some Meninist saying women are too stupid for physics). Science benefits from more perspectives. Without a deaf woman, we wouldn't have sonification. Or maybe I'll just time-travel back to high-school and thank my vice principal for coming to chemistry class to say "girls don't belong in chemistry". I mean, obviously that wasn't meant to discourage anyone, right? Maybe listen to lived experiences before spouting off.

Children are not in my future, but I do dearly hope someone's taking their kids to watch these and talk about them. As part of the discussion, getting girls to see this *could* be them, and they are no less cool for being smart, and getting the boys to see smart women. Same with YT "Physics Girl." I think the outtakes are an important part of seeing the very human side of what it means to be have a Phd in Astrophysics or any other area of STEM. Reality really doesn't give a damn for one's gender. Reality just is, and it is there to be discovered!

The word _planet_ is often used in different ways, to mean any object that revolves around a star, or even around any other object. You need consider the context it appears in. The distinction between asteroids, moons, dwarf planets and planets isn't as important as the classification of stars, I think. The smaller objects are classified more based on where they are and how they formed.

Honestly, what if their theoretical Dark Matter and Dark Energy do not exist? Which is what I believe. There is no tangible evidence, none that has been sampled, none has been seen, does not interact or have a force of collision, yet has so much gravity? I say it is impossible for it to exist.

@@bosstowndynamics5488 , Effectively, your answer makes no sense and is not related to my statement. Photons are well established. Dark Matter is not. Gravity requires mass. Mass requires substance. This Dark Matter has no mass, as I stated, it does not interact with collision. I am stating, that expansion is a false claim also. If you understand time lapse photography, photography of deep field galaxies, you might understand that we would see that fast expansion that is described. That expansion would be seen as blurry images to streaks. Just as we have star trails with time lapse photography of our sky, we might be able to show this with a faster than light expansion. So, no, my insight on this is not weird. It is normal. Believing in something that is nothing is what is weird.

Thanks for the explanations! Really interesting. Ever since I discovered my first Class-Y and Class-T objects in Elite Horizon (and nearly got swallowed trying to probe it), I wondered "what are these things? What do they do? How do they form? Why are they not planets? Or are they not stars? Or neither?Why does no one talk about them? " But then, haha, you did, so thanks a lot. Solved a lot of riddles.

Dr. Becky... a lady with an eye for astronomy, but an ear for paleontology! Another great episode. These rogue planets and brown dwarfs are going to be important resource spots for colonizing the galaxy. They hold plenty of material, and yet they are safer and last longer than stars. Once their galactic orbits are charted, they could be used as way stations to resupply & build ships for as long as the galaxy will last. (Although we'll have to recalculate everything during/after the AndromeWay collision era.)

@@MarkTillotson Oh, I'm not talking about living on or colonizing them. I'm talking about using them as raw material. Scoop up what you need and move on. A gas giant is fuel and eventually metals for a very very long time, to power and build millions of habitats over eons of use. As far as I'm concerned, planets have 2 uses. Either they are luckily fit for a terraforming spot to grow new wild life and see what eventually evolves, or you strip them down for ingredients to build more spacefaring civilization. In our solar system alone, we have mercury, venus, all the asteroids and dwarf planets, and most of the moons, plus uranus itself as entirely disposable commodities. Chopping them up for redistribution just makes the rest of the system orbits more manageable. We can drop enough of the scraps onto mars to grow it into a planet worth terraforming, with a proper working core and so on. In my opinion, lumps of dead stuff floating through space have no ecology or conservation value. Life first!

Yes, very cool earrings. More brontosauruses to match your necklace. And I love that color nail polish. But more to the point--other than Arthur C. Clark writing sci-fi about mystical monoliths pushing the mass of Jupiter high enough to ignite (if that's the word) in "2010" (I think), this was the first I'd heard of this weird domain between big planets and small stars. Fascinating to think of a planemo with circling planets. I need to watch this one again...... Thank you! (Deuterium burning... .08 solar masses down to Jupiter-size... so interesting. I always thought of brown dwarves as just kind of failed stars, but it's really all much more interesting. Golly....)

This is going to sound odd but some of this I actually learned from exploring star systems in the game Elite Dangerous. You can actually see planets and stars of all sizes and densities up close and side by side (relatively) and it really makes you contemplate those cut-off points and what bodies in that "grey" area look like. You literally could have used clips and stills from that game in this video to help visualize everything you discussed here.

Our day to day lives are focused on such a limited scale. It's good to enlighten the soul on a universal level sometimes!

One is clear for me - the woman whom I'd look forward to listen to the whole day talking must be an astrophysicist! :) I like the way you are challenging your audience to pay attention and think more and not ''diluting'' the subject for easier understanding (although I'm certain that like 98% information doesn't make it in the video). Are you doing it on purpose, or is it just the way you explain things? :D And last, if it's possible in the future, make a video of how scientists combine different light frequencies to take photos of galaxies or the technique astrophysicist use to discover properties of exoplanets? Thanks! Btw, I love your accent! :)
