Stars are balls of luminous plasma, held together by gravity. They can be seen twinkling overhead from our planet each night. They are enjoyable to look at, but also have been used as navigation tools for centuries.
The name is Chinese is 天蝎座 ( tiānxiē zuò ), which means 'The heavenly scorpion constellation'
First you have to prove a parallel universe exists. It is theorised that they exist, but it is not proven. If they do exist, it is doubtful we could ever go there. We are designed for this one, for the physical laws the operate here and if we did go there, we probably wouldn't be able to survive. A...
5.88 x 1014 miles = 1 ly. 1 mile = 1/5.88 x 1014 ly. 5.417 x 1014 miles = 5.417 x 1014 /5.88 x 1014 ly =0.9213 ly
(circumpolar - our view of the constellation on Earth) . Constellations are circumpolar because they are only how we viewthem on Earth. The constellations would be different on anotherplanet or at another viewing point. They are circumpolar since theyare at different distances in relation to each...
No. It receives more energy than it gives off. That is one of the reasons it is referred to as an "Ice Giant", along with Neptune.
The Sun produces energy by the nuclear fusion of hydrogen intohelium in its core. What that means is that, since there is a hugeamount of hydrogen in the core, these atoms stick together and fuseinto a helium atom. This energy is then radiated out from the coreand moves across the solar system. The...
All constellations have stars of all temperatures. Libra is noexception to that. So there isn't some specific temperature aboutthe stars in it.
Libra is a constellation, a specific part of the celestial sphere.So it is not a physical entity that could have a temperature. Ifyou are referring to the stars that can be found within itsboundaries, they can be any temperature that applies to a star(anything between 3000K and 20000K)
No , it is not a 'real' galaxy, merely one that exists inside the movie world. It is based upon Science Fiction, and you will not be able to travel to it.
The stars comprising Cassiopeia are in the same positions (with minute shifts unnoticeable without advanced telescopes and measuring equipment) now as they have been for thousands of years- If someone decides to redraw the borders they can do that whenever they want but it will not affect the...
Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1%trace elements, mainly Argon. The martian atmosphere consists of96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen presentonly as a trace element. Where you to inhale the martian atmosphereyou would suffocate. The atmosphere...
Constellations are stable (at least in our lifetimes and that of humanity). They change so slowly as to be unnoticeable.
The second nearest star to Earth is Proxima Centauri, 4.25 lightyears away and 270,000 times farther away than the nearest star,the Sun!
Quasars (Quasi-stellar radio source) emit billions [10 9 ] or even trillions [10 12 ] times the energy of a star in our galaxy, the Sun. Quasars show a very high redshift, which is an effect of the expansion of the universe between the quasar and the Earth. They are the most luminous, powerful, and...
We remain about the same distance during the entire galactic rotation (220 million years).
We can see about 6500 stars just with our eyes when the sky is dark enough.With the sky being brighter,the number decreases.
Stars can be classified by temperature, pressure, age, size orcolour. Star classification according to size is found outusing temperature and pressure classifications. The temperaturetells them the surface brightness of a star, and the pressure tellsthem an approximate size of the star, which...
Procyon is actually a binary system. The heavier component, ProcyonA, has about twice the radius and 1 and a half times the mass ofthe Sun. The smaller, lighter Procyon B is about 3/5 the mass and1/8 the radius of the Sun.
We can only see half of the sky at one time. And in the morning or the evening,it's too bright to see stars.
Quasars are some of the most distant and luminous bodies we canobserve. Since we measure them to be incredibly far from our owngalaxy, in the order of billions of light-years, astronomersbelieve that they are several billions of years old as their lightwould have taken that long to travel to us....
The sun has amagnetic field that gets twisted around inside the sun as it spins.There are places on the sun where this magnetic field rises up frombelow the sun's surface and pokes through, creating sunspots . Sunspots are magnetic and often have a north and south pole like a magnet. hope this...
Thereare about 2,500 stars visible to the naked eye at any one point atany one time on the Earth, and 5,800-8,000 total visible stars. Butthis is a very tiny fraction of the stars the Milky Way is thoughtto have! Astronomers estimate that there are 200 billion to 400billion stars contained within...
Energy sources that don't depend on the sun are: Nuclear Energy andWindpower.
Scientists measured it in light years. The Milky Way takes 100000years to get from one side to the other at the speed of light.
Quasars are galaxies which are much brighter than ordinary ones. they are as bright as 100 galaxies put together. they are also as powerful as several blackholes put together. quasars are seen as faint light from the earth this shows how powerful they are to be seen from the extreme end of the...
No. The sun is too hot for water molecules to stay together. Thesun's source of energy is hydrogen, which makes up most of itsmass.
The decrease is caused because it makes the spiral galaxy movefurther apart.
Constellations are named for mythological creatures from stories.
The black hole represents a crust in the space which swallows anything that passes through it. Even light cannot escape from a black hole! There is a particular radius for a mass to become a black hole when it is squashed. This is known as the Schwarzschild radius and for the body to become a...
Hydrogen makes up roughly 75% of the sun.
In the Northern Hemisphere from June through February
Galaxies occur solar systems that formed after the universe exploded.
Saturn's distance from the Sun in miles is 891 million miles.
No one knows exactly why, as we can't see under its clouds. There are several ideas, but all come down to some internal source of excess heat: maybe gravitational, radioactive decay, fission, fusion, etc.
It is much closer to us than other stars, the next nearest star is about 4 light years away, to put that in perspective, we are 8 light minutes from our Sun. As stars go our Sun is an average yellow star. However we are learning that the majotiy of stars in the universe are red dwarfs. Red dwarfs...
Neutron stars. Pulsars. And occasionally black holes.
Almost everything we know today about the stars and their life cycle is a direct result of the correct interpretation of our main source of evidence on the stars (their spectra) by a graduate student of very Young appointed Cecilia Payne. Before its discovery in 1925 astronomers thought all the...
The sun doesn't. It would be impossible
First of all, there's two theories of relativity. The one on normalrelativity which indicates that an object that is moving very fastwill experience less time than one that is stable. The one onspecial relativity indicates that the more gravity an object isputted into, the less time it will suffer...
Each cycle for the sun is about 10-11 years.
The diameter of the Sun is approximately 1 million miles; the distance between the Earth and the Sun varies from about 91.5 million to 94.5 million miles. So the distance between is MUCH greater than the diameter.
It is our galaxy the Milky Way. If you go to the Local Cluster you can look at Earth and in Mass Effect 1 you have a mission on the moon (Luna).
yep, Earth: Milky way galaxy, saggitarius arm, sol, third orbit. :D all you need to do is ask a nerd :P
To keep the mood fun, ask questions about things which the person is interested in. For example, if they love watching pretty little liars, ask them who they think a is (bad example, sorry :P). If you don't know about their interests, ask them- e.g. 'whats your favourite tv show?'. Maybe you could...
Yes, Aphrodite does have a constellation. I wish your question had more to answer. I hope that answers your question. If not please message me on my message board to ask more specifically, I WILL have an answer.
A white dwarf is not considered a "dead star." It is considered adying star, but not dead yet. A white dwarf is at its smalleststate and could become a supernova when its center runs out of fuelto burn.
Ah, a math quiz. If the nearest galaxy is 2000000 light years away then it would take 20 Milky Ways laid end to end to equal that distance. Now the problem is that Andromeda is the nearest spiral galaxy and it is 2.5 million light years away, so it would actually take 25 Milky Ways.
If you mean the distance then it's 50 thousand light years. Which is 2.95 × 10 17 miles.
Constellations don't actually exist, (the stars in them exist, but... with very few exceptions ... the only connection between thestars in any given constellation is that they happen to be in moreor less the same direction from Earth, though they may be at vastlydifferent distances from Earth, so...
At higher masses, the star's gravitation will be greater, resultingin more pressure and a higher temperature. This will increase therate of nuclear fusion - and thus make the star use up its fuelfaster.
The galaxy was named after milk because when early astronomers looked at the sky they noticed a band of stars that somewhat looked like milk!
I am not really that sure ,but i think that it is hydrogen and heluim considering that its a red giant
Proxima Centauri is 4.3 light years from the Sun.
One constellation holds the Big Dipper, and that constellation isUrsa Major. The Big Dipper is located at the end of the body andthe tail of the Great Bear constellation. The Big Dipper isconsidered a minor asterism within the constellation of Ursa Major,and the stars that make up the Big Dipper are...
The sun is a star, therefore it shines. But it doesn't make other stars shine.
The constellation has a total of 281 stars in the area defined bythe constellation boundary of which only 11 are main stars.
The planets depend on the time of year.
It is a G-type giant star.
The Orion constellation can also be referred to ''The Hunter''
The distance to Alpha Centauri is about 4.3 light-years.
To learn more about the universe. For me personally, I enjoygetting outside at night and observing. I look at stars that changein brightness - variable stars - and this contributes to ourongoing long-term database.
Luminous bodies are objects which exhibit their own light. example- sun. Non luminous bodies are objects that reflect light from luminous bodies. example- moon
Supergiant stars are dying stars that still undergo nuclear fusion,they are made up of hydrogen and some other elements such as oxygenand magnesium. Neutron stars are exposed cores of supergiant stars,they are made up of neutrons, and they cannot undergo nuclearfusion.Supergiant stars are aging...
well, it doesn't really move. the earth is tilting either away, ortwards the sun a it is evolving/ rotating around the sun. that iswhy we have night and day. sorry if you are religious.
It's made of dejection.
-3.64 is the absolute magnitude of Polaris.
Gravitationally confined thermonuclear fusion of hydrogen into helium inside a small volume at the core of the sun, where temperature is so high that the electrons and protons of the hydrogen atoms are completely separate gasses (plasma) and pressure is so high that the density of these gasses is...
That will depend on the speed. At the speed of light, it shouldtake about 26,000 years, since the center of the Milky Way is about26,000 light-years away from us.
The sun will never blow up. The sun will died in 5 to 7 billionyears, but the process will be gradual.
No. The only star in the solar system is the sun. The stars you seeat night are much farther away.
The only way we'll ever know if Betelgeuse has "gone supernova" iswhen we see it. Of course, by the time we see it, the event willactually have happened some 640 years earlier, because that's howlong its light takes to reach our eyes. Despite being only about 10million years old (young, by stellar...
According to data found in the Wikipedia, the Pistol Star has 306 times the diameter of our Sun. Raise that to the third power (306 cubed) to get the ratio of the volumes. Please note that due to the fairly large distance of the star, the numbers may not be entirely accurate. Of course, there...
Because it does not have enough mass to crush itself with it's gravity.
Andromeda is the wife of Perseus and the only mother of hischildren seven sons: Perses, Alcaeus, Heleus, Mestor,Sthenelus, Electryon, and Cynurus as well as two daughters,Autochthe and Gorgophone.
Andromeda was a mortal princess of Eithiopia and later wife ofPerseus and queen of Mycenae.
This question doesn't make sense
Neither, dark matter is an undetectable yet massive existence within our universe. It is spread out relatively smoothly, not bunching up in particular locations. For more information, search dark matter images (computer simulated), they help the visualization of it.
i do know that its a diffuse mass of interstellar dust or gas or both, visible as luminous patches or areas of darkness depending on the way the mass absorbs or reflects incident radiation. Hope that helps. :)
Black holes havent quite been explained yet. Some scientists still havent found out why black holes are created, and what creates them. But people have suggested that black holes are usually made o rubbish. (Im talking about junk that is left in space such as crashed space ships, or either broken...
Well I think it would all just float in tiny particles or just disappear!
No, the Koopa Kids don't appear in Galaxy 2.
Depends on how a galxy's size is compared to another one. Some galaxies are larger than others. But in light-year lengthwise, they are very big. A light year is equal to almost 6 trillion miles or 10 Pm (Petametre)
