The scientists use a technique referred to as reverberation mapping, which measures the radiation thrown off by a rotating disk around the black holes or stars or the planets. It is a very very like very hard maths involved in it like angles which is the most imp aspect for measuring galaxies and stars. It is very hard to explain here coz I can't type it so lengthy.

there are instruments to measure all sorts of waves in the universe, from visible to invisible. light waves, radio waves, scientists can detect light that was so far away at one point that it has since collapsed and isn't giving light anymore.

The Bootes Void is one of the weirdest and possibly scariest things scientists have found. Its a big section of space with no stars or anything in the midst of a region of a galaxy that should be full of them. All sorts of theories of what's going on. From cosmic level disaster scenarios snuffing out stars in an expanding ring to Dyson spheres being built around all the stars in the cluster being proof that there is an advanced civ over in that area. Everything is wild speculation but its fun to dream none the less

[@SpearM3064]

To be fair, it _does_ have galaxies. It's just that they're so far apart that we have a hard time seeing them with our telescopes. Since 1987, scientists have discovered about 60 galaxies in the Bootes Void, and they estimate that it may have as many as 2 thousand. However, you're not wrong... it should have far more galaxies than it does. There's seven other "voids" that we know about, but the Bootes Void is the largest of them.

Not to mention the 1 400 000 000 years for Boötes Void if the signal had something to bounce back from and did not get too dispersed.

Fun fact about betelguese: It's so old and close enough that when it dies, it will die in one of the most powerful explosions in the universe called supernova and will be almost as bright as the night moon in the day.

[@cplhotpockets]

word of advice about space. Bigger diameter for stars doesn't necessarily mean that they're more massive you're probably going to see all of these stars that make our son look like a flea in comparison but they are so incredibly defuse that you probably wouldn't even know you passed their interior, meanwhile the most massive star we found which is around 300 times the mass of our sun is actually only a little bit wider compared to these other stars that are about the size of the orbit of Saturn or Jupiter which are in fact much less massive.

A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives

Also, these numbers are often pretty accurate (+/- 2% margins of error).

[@HouTexHemi]

Answers to some of your questions: a Nebula is a cloud of gas and/or dust in interstellar space, there are several types but thinking of it as a gas cloud is the simplest idea. The cloud can be illuminated or backlit by stars. The Small Magellanic Cloud is a dwarf galaxy containing a few hundred million stars. NGC1277: The NGC stands for New General Catalogue, basically just a naming scheme astronomers used to catalog "deep sky" objects that are outside the solar system, it could refer to star clusters, nebulae, galaxies, etc. NGC1277 happens to be a galaxy. The sizes given in this video are the diameters of the objects, like how big it is from side to side.

[@alanblack306]

I can't get over how many adults have reviewed this video with absolutely no clue about what they are watching. Did none of them look up at the sky as a kid and wonder what lies beyond the moon and sun. Did none of them at least glance through a picture book about it as a kid - to at least get a basic understanding? How could any kid not Google this stuff just out of normal human curiosity?

A nebula is giiiiaaaaannnntttt gas cloud that forms when stars explode.

[@constantinvaldor1498]

If you want to measure the size of a star, just point your telescope at it and take a picture. Measure the angular size of the star in the image, then multiply by the distance to find the true linear diameter. What's so hard about that? :-)

[@DrD0000M]

The universe is at least 250 times the size of the OBSERVABLE universe and quite possibly even infinite. Light beyond the edge of the observable universe can no longer reach us as the space in-between the edge and us is expanding faster than light itself. Everyday, more objects move past the edge, disappearing from our reach and making OUR universe emptier even though it becomes larger.

[@dmoney-yz9ly]

A nebula is a fancy word for giant gas cloud

[@williamozier918]

Early modern astronomers determined teh size o fnebula and such by using triangulation: You use two telescopes spread as far apart as possible, point them both at the same object, and then you measure how far apart the telescopes are, then measure the angle between them, you can then use the geometric math of triangoles to figure out how far away the object is.

[@cplhotpockets]

Also when you asked about Cat's Eye Nebula and Helix nebula, a nebula is actually just a bunch of gas that typically comes from a big star that blows up leaving a bunch of leftover material floating around and since the Stars blow up with quite a bit of energy this stuff is flying in all directions slowly drifting apart and I totally get to be so cute cousin spacers not much to slow you down. So that's how you get with this kind of stuff that's several light-years wide and each light year is nearly 10 trillion kilometers. However it doesn't look that bright with that dense if you're inside, instead from the inside you would actually look very very diffuse and you probably wouldn't even know you're inside unless you start at the center which actually seems somewhat right and dense

[@dalton6173]

I am glad you finished watching it especially because it was frustrating. That frustrating was your mind not wanting to believe what you were being told. A fear of the unknown and of how small we all really are. I have some to the understand that anger is fear in action and we all know frustration is a cousin of anger. There for instead of asking yourself why did this frustrate you, ask yourself why did this video make you afraid. Hope all is well for you, I know this was a year ago so hopefully you have taken time to learn more since then.

[@buttegaming4872]

Your reaction is priceless 😆😆😆

[@Stacy55ish]

Knowing the distance (measured using the parallax method ), we can multiply the angle subtended in radians by the distance to obtain the physical size (the diameter) of the star. Measure the angular size of the star in the telescopic image, then multiply by the distance to find the true linear diameter.

Note: Some measurements are used which are called 'AUs' (astronomical units), which is the Sun to the Earth -- 1 AU (93 million miles). If I can recall. Light Years are a measure of distance, not time, yes. If I can recall, again, 1 Light Year equals 3 trillion miles, but you'll have to check that. So, 100,000 AUs = 3 Light Year = 9 trillion miles = Helix Nebula.

[@SpearM3064]

Since you asked... NGC 1277 is another _galaxy,_ about 220 million light years away. (NGC means "New General Catalogue", and it refers to objects that are non-star like. Galaxies, nebulae, globular clusters, supernova remnants, etc.) It was first discovered in 1875 by Lawrence Parsons, 4th Earl of Rosse. The Small Magellanic Cloud is another galaxy, about 200 thousand light years away, containing several hundred million stars. It's part of the "local cluster", consisting of the Milky Way, the Small Magellanic Cloud, and the Large Magellanic Cloud. _IC 1101_ is a supergiant elliptical galaxy over a billion light years away. You might think Omega Centauri is another galaxy, but it's not. It's a "globular cluster" in our own galaxy, about 17 thousand light years away, and contains about 10 million stars. The _Bootes Void_ is one of about eight known "voids". It actually does have galaxies, but they are so far apart that we have trouble seeing them even with our most powerful telescopes, so it looks like a black void in space (hence the name). We've discovered 60 galaxies within the void and estimate that it has two thousand galaxies. TON 618 is the most massive quasar ever detected. Essentially, a quasar is an _accretion disc_ of hot gas swirling around a black hole in the center of a galaxy. The black hole at the center of TON 618 is _66 billion times the mass of the sun._ The event horizon is about 390 billion kilometers in diameter (that's 40 times Neptune's orbit). The gas is swirling around the black hole at speeds of up to 7000 km/second (4350 miles per second). It shines as brilliantly as 140 _trillion_ suns, making TON 618 one of the brightest objects in the _entire known universe._ A _planetary nebula_ is a giant cloud of hot gas blown off a star during the red giant stage of its life; it's basically the evidence of a dead or dying star. Our own sun will form a nebula when it dies. It's likely that the Cat's Eye Nebula (NGC 6543) is the product of a binary star system. The Helix Nebula (NGC 7253) is probably the result of a star that's almost, but not quite, massive enough to go supernova. The Orion Nebula (NGC 1976) is NOT a "planetary nebula". It is a _diffuse nebula._ The difference is, it's not a place where a star has died. Instead, it's a cloud of interstellar gas that glows because it's where new stars are starting to form. Observations of the nebula have revealed approximately 700 stars in various stages of formation within the nebula. Proxima Centauri is actually the closest star to Earth, "only" 4.2 light years away, a red dwarf. It has two known planets, one of which lies in its habitable zone; however, because the star undergoes intense flare activity, it may not actually be habitable. Sirius A is another nearby star, 8.6 light years away. It's also the brightest star in the night sky. It has one companion star, a tiny (and massive) white dwarf, and may have a second companion, perhaps a small red dwarf or a large brown dwarf. If it has planets, none of them are likely to be habitable because of all the solar radiation from two (possibly three) stars. Vega is in the constellation Lyra, and is the fifth-brightest star in the night sky, about 25 light years away. It's only about 10% the age of the Sun, but because it's twice as massive, its lifespan is also only 10% that of the sun. Scientists are reasonably sure it has a dust ring, but haven't found a planetary system. (However, they can't rule it out either. It might have some planets that are obscured by the dust so we haven't found them yet.) Arcturus is the _fourth_ brightest star in the night sky, about 36.7 light years away. It is a red giant, and has probably burned up most of the hydrogen in its core. It might possibly have passed what is called the "helium flash stage", which is where it has started fusing helium into carbon. It isn't massive enough to begin fusing carbon into iron, which means that it'll end its life in a few billion years as a white dwarf (so will our sun, btw). Rigel is a blue supergiant star about 860 light years away. Thank goodness for that, because it's massive enough to go nova, leaving behind either a black hole or a neutron star. It's only a few million years old (compared to billions of years old for other stars), but it's already burned up the hydrogen fuel in its core and is now fusing helium. That means it only has a few million years before it pops. When a star goes supernova, you want to be at least 50 light years away. That's the "kill zone" because of all the gamma rays given off by the explosion. Betelgeuse (pronounced "beetle juice") is the largest visible star in the night sky, and is about 500 to 600 light years from Earth. It's _currently_ a "semiregular variable red supergiant" (meaning its brightness fluctuates over a somewhat regular interval). Like Rigel, it will also become a Type II supernova; it's estimated that it'll pop in about 100,000 years. VY Canis Majoris is also a variable red supergiant, about 3900 light years away. It is one of the largest known stars by radius, and is also one of the most luminous and massive red supergiants, as well as one of the most luminous stars in the galaxy. This one is also going to become a supernova in about 100,000 years. I think you're seeing the trend here. UY Scuti is _also_ a variable red supergiant, about 9500 light years away. Unlike Arcturus, however, it _is_ massive enough to start fusing carbon into iron before it goes supernova. Want to know something scary? _It's not even the biggest star we've detected._ THAT record goes to Stephenson 2-18, which is about 2150 times the size of the sun. (UY Scuti is "only" about 1700 times the size of the sun.) To put that into perspective, Stephenson 2-18 is about 3 _billion_ kilometers, or 1.87 billion miles in diameter. I want to take a second to put some scale into the sheer _size_ of the galaxy as a whole. I mentioned that Proxima Centauri was about 4.2 light years away. If Earth was the size of a grain of sand, Proxima Centauri would be a pebble _six miles away._ Using current technology, it would take 78,000 years to get there. At 20% light speed, it would still take 20 years. You can imagine how long it would take to get to UY Scuti (remember, 9500 light years). Where's warp drive when you need it? ;^)

Excellent information, in terms us "mere mortals" can understand!

[@komisar3937]

Good stuff, thanks for all that is language that we can kinda sorta pick up on. :)

[@SpearM3064]

@@komisar3937 You're welcome! I don't actually work for NASA or the ESA, in case anyone was wondering. I'm just an amateur astronomer who (when I was 6 years old) wanted to be an astronaut when I grew up, and a lifetime member of _The Planetary Society._ Years of working in customer support have taught me how to simplify all the jargon into terms that non-scientists can _mostly_ understand. Speaking of which, if there's anything you didn't quite understand and want more information about, let me know, and I'll try to help.

Look up the “how far away is it” video series by David Butler on KZbin if you wanna know how scientists measure these distances

[@Infrared01]

That was a great program

[@jusdon8711]

The Hubble telescope takes the pics / brightness and physics figures out the rest… when you turn on the 📺 and see static there’s is light in that from the oldest lights in the universe

[@Imafuckingweeb]

Some of these are actually estimates since we can only see these through telescopes

that's why marines worry only about their gun and gear,mission details go to commanders....

Ryan, if your going to do Space and Light Years reactions, have some aspirin handy...you're gonna need it!

The volume is very low for many of your videos, if you can increase the volume some while editing it would help us laptop users out. Thanks!

[@odie146]

It's not just laptops, but also phone, streaming stick devices and PCs. It's fun when you forget to turn it down again 😉

[@phillipnunya6793]

I demand you watch more of the space.

[@pharmdiddy5120]

ok yep, i do like some space stuff

[@BenEmberley]

NGC 1277 is the Super-massive Black Hole in the Galaxy of the same name, located in the Perseus constellation.

[@lorgrenbenirus]

Only thing what matters really is that humans and their stupid egos are such a tiny and insignificant things on the grand scale of things that it's not worth measuring even.

[@charlesmclain6558]

I've seen some really big egos

[@Liampowell4]

yes space stuff

[@lucyb9276]

I'd love to see you react to more space and universe videos
