Sweet bit of trivia there @mysticalmysty ! I never knew you could be fined for whistling on Sunday anywhere! 😯

Now is that 1,000 dollars, because it looks like you said 1.000, or one dollar @mysticalmysty 🤔

Anyway let me see if I can wrangle us up some more juicy trivia for your hungry eyes! 😄

Okay as you guys were aware in my previous post I'm quite fascinated with astronomy and stuff involving space. Therefore, my next bit of trivia involves something you guys may also know something about... Stars! 💫🌠⭐🌟☆😆

As some of you know stars come in different types. However, a star is just a star, right? Sure there are some differences in terms of color when you look up at the night sky. But they are all basically the same, big balls of gas burning up to billions of light years away, right? Well, not exactly. In truth, stars are about as diverse as anything else in our Universe, falling into one of many different classifications based on its defining characteristics. 🤔

All in all, there are many different types of stars, ranging from tiny brown dwarfs to red and blue supergiants. There are even more bizarre kinds of stars, like neutron stars and Wolf-Rayet stars. And as our exploration of the Universe continues, we continue to learn things about stars that force us to expand on the way we think of them. Let’s take a look at all the different types of stars there are! 😉

(Note: Since I don't want this to become a massively long post I will try to sum up some of this information, BUT if you want I can give you guys a link to it later on if you want! 😃)

1. Protostar: A protostar is what you have before a star forms. A protostar is a collection of gas that has collapsed down from a giant molecular cloud. The protostar phase of stellar evolution lasts about 100,000 years! 😲

2. T Tauri Star: A T Tauri star is the stage in a star’s formation and evolution right before it becomes a main sequence star. This phase occurs at the end of the protostar phase, when the gravitational pressure holding the star together is the source of all its energy. Stars will remain in the T Tauri stage for about 100 million years! Obviously this is much longer than a Protostar phase 🤯

3. Main Sequence Star: The majority of all stars in our galaxy, and even the Universe, are main sequence stars. Our Sun is a main sequence star, and so are our nearest neighbors, Sirius and Alpha Centauri A. Main sequence stars can vary in size, mass and brightness, but they’re all doing the same thing: converting hydrogen into helium in their cores, releasing a tremendous amount of energy! Additionally, a main sequence star can theoretically grow to more than 100 times the mass of the Sun! 🤯

4. Red Giant Star: When a star has consumed its stock of hydrogen in its core, fusion stops and the star no longer generates an outward pressure to counteract the inward pressure pulling it together. A shell of hydrogen around the core ignites continuing the life of the star, but causes it to increase in size dramatically! It can be 100 times larger than it was in its main sequence phase, and also this phase of a star's life only lasts a few hundred million years! 😯

5. White Dwarf Star: When a star has completely run out of hydrogen fuel in its core, and it lacks the mass to force higher elements into fusion reaction, it becomes a white dwarf star. The outward light pressure from the fusion reaction stops and the star collapses inward under its own gravity. A white dwarf shines because it was a hot star once, but there’s no fusion reactions happening any more. The cooling process of these stars takes upwards of hundreds of billions of years, so no white dwarfs have actually cooled down that far yet! 🤔

6. Red Dwarf Star: Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars, but they have such low mass that they’re much cooler than stars like our Sun. Astronomers estimate that some red dwarf stars will burn for up to 10 trillion years. The smallest red dwarfs are 0.075 times the mass of the Sun, and they can have a mass of up to half of the Sun.

7. Neutron Star: If a star has between 1.35 and 2.1 times the mass of the Sun, it doesn’t form a white dwarf when it dies. Instead, the star dies in a catastrophic supernova explosion, and the remaining core becomes a neutron star. If stars are even more massive, they will become black holes instead of neutron stars after the supernova goes off! 😳

8. Supergiant Star: The largest stars in the Universe are supergiant stars. These are monsters with dozens of times the mass of the Sun. Unlike a relatively stable star like the Sun, supergiants are consuming hydrogen fuel at an enormous rate and will consume all the fuel in their cores within just a few million years. Supergiant stars live fast and die young, detonating as supernovae; completely disintegrating themselves in the process! 😧

Phew that was a ton of text, and I even cut out quite a bit! 😖 Anyway I hope you guys didn't get too bored with this Star Trivia. I felt the need to give this trivia as I am a SeraphicStar after all (wonder why they didn't mention me... hmm.... 🤣)

Take care everyone and have a great rest of your weekend! 😆

1.00 = 1 yes, but 1.000 = 1 really ?

If you're a coffee lover, first, welcome to the club. Second, you probably know the pain of overdoing it on caffeine—and the crash that happens afterward. Don't even get us started on the anguish of trying to cut down on the stuff. Well, none of us are imagining it: as of May 2013, the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) lists caffeine withdrawal as a mental health disorder. ☕️

Speaking of coffee, kopi luwak ( civet coffee ) is the most expensive coffee in the world still, is the coffee that include partially digested coffee cherries, eaten and defecated by Asian palm civet. Fermentation occurs as the cherries pass through the civet’s intestines, and after being defecated with other fecal matter, they are collected. The coffee itself selling for between $ 100 - $ 500 per pound in US market.

Otterly adorable.... Dozing otters hold hands while they nap!

It’s true, Otters are known to hold hands in groups - called a raft - while they eat, sleep and rest, to prevent families losing each other, despite the water's chilly temperature, the otters were in no danger of catching a cold as their fur is one of the densest in the animal kingdom - with up to a million hairs per square inch.

SeraphicStar

Hey those are some sweet trivia tidbits guys! @mysticalmysty I had no idea that they sold coffee that had been previously defecated (Ewwww! 🤢)

Also @MiaChristine your adorable otter holding hands gif was just too much! It's also quite interesting why they do this as well 😉

Okay fellow trivia connoisseurs today I wanted to delve into something that really fascinates me. It is again related to astronomy, so I hope you guys are interested in it! 😁

Today's topic is about Black Holes! 😱

Be warned as I love this topic so much it might be very difficult for me to cut out much material... Therefore I hope you have some coffee/meal prepared as this could be a bit of a read 😯

Now a black hole isn't actually empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space (and to me as well! 🤩)

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole (Einsteins theories helping explain these is also pretty awesome imo 😄)

Scientists can't directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits x-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them - emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others (As I'm quite fascinated with this I will try to show some neat pictures of what people believe a devouring black hole looks like! 🤩)

Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the total mass of the star is large enough (about three times the mass of the Sun), it can be proven theoretically that no force can keep the star from collapsing under the influence of gravity. However, as the star collapses, a strange thing occurs. As the surface of the star nears an imaginary surface called the "event horizon," time on the star slows relative to the time kept by observers far away. When the surface reaches the event horizon, time stands still, and the star can collapse no more - it is a frozen collapsing object (Time stopping can you imagine that?! 😳)

Although the basic formation process is understood, one perennial mystery in the science of black holes is that they appear to exist on two radically different size scales. On the one end, there are the countless black holes that are the remnants of massive stars. Peppered throughout the Universe, these "stellar mass" black holes are generally 10 to 24 times as massive as the Sun. Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole's gravity, churning out x-rays in the process. Most stellar black holes, however, lead isolated lives and are impossible to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone (This tidbit surprised me a great deal as I'm not sure how we haven't gotten sucked into one yet! 😱)

On the other end of the size spectrum are the giants known as "supermassive" black holes, which are millions, if not billions, of times as massive as the Sun. Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas (I can't even fathom that massive of an object... 😳)

Well I believe that's enough about black holes, and if you reached this far I applaud you! I hope this trivia was enlightening to you guys as I always loved reading and learning about these! 😆

P.S. I forgot to mention that I read this somewhere as well, but it's a bit more science-fiction then fact regarding black holes. If you were able to survive being sucked into a black hole you could theoretically look at the back of your own head! 🤯

Here is something a little bit dizzy... Embrace yourselves! There are about 7,000,000,000,000,000,000,000,000,000 atoms in a human body. How do you even pronounce this number?

SeraphicStar

I have no idea how one would say that large of a number @firebombmarkus!

Anyways I believe I've been in fact making these trivia tidbits too long to be just "tidbits", so I will try to keep it short for you guys. Perhaps my choice of topics, or my lack of summarizing skills is the issue I don't know... 😥

Well, I guess I will try another attempt at this, so let's talk about something non-astronomy related.

I have multiple books where I am (and the Internet, or course!) that are filled with amazing and interesting facts! So I thought it would be neat to share all sorts of trivia facts with you guys regularly(this may not entail every day, but keep a look out for new facts regularly)! If you would like to ask me a question, or would like to share your knowledge, by all means do so! In fact, here is one now: According to the Guinness Book of World Records 2019, there are approximately 4.4 billion poeple living within the continent of Asia! They also said that this is roughly 60% of all the world’s poeple! I hope you found this interesting, have a wonderful evening, and check back later for more fun trivia facts! Keep being sweet you guys!
