Orion (astronomy)
Orion (astronomy), constellation located on the celestial equator east of Taurus. It is oblong, with three stars in line near its centre. It is represented on pictorial charts as the figure of Orion, the hunter in Greek mythology, standing with uplifted club. Three bright stars represent his belt and three fainter stars aligned south of the belt represent his sword. Alpha () Orionis, or Betelgeuse, is located in the left corner of the oblong, corresponding to Orion's shoulder. Beta (β) Orionis, or Rigel, is diagonally opposite Betelgeuse. A faint, misty patch surrounding the three stars marking Orion's sword is revealed in long-exposure photographs made with powerful telescopes as a spectacular mass of bright and dark gas and dust, many hundreds of light years across, in which stars are being born.
Pleiades (astronomy)
Pleiades (astronomy), loose cluster of 400 to 500 stars, about 415 light years from the solar system in the direction of the constellation Taurus. The stars are about 1 light year apart, on the average, and photographs show them to be surrounded by a nebulosity that shines by their reflected light. The cluster was named by the ancient Greeks after the “Seven Sisters” of mythology. Observers have claimed to be able to see with the naked eye as many as 12 of the stars in the cluster.
Pleiades
The Pleiades is an open star cluster which is visible to the naked eye in the constellation Taurus. The Ancient Greeks saw seven stars in the cluster, and named them after the Pleiades, the seven daughters of Atlas and Pleione. According to myth, the hunter Orion was in love with them and pursued them until the gods took them to safety, transforming them first into doves, and then into stars. Telescopes have shown that there are up to 500 stars in the cluster.
dont wish to be any thing
but what you are
and try to be that perfectly:)
Variable Stars, stars that change in brightness as seen from Earth. The term encompasses stars that actually fluctuate in their light output (intrinsic variables), and stars whose light is interrupted on the way to Earth by some external factor, such as another star or intervening dust (extrinsic variables). The light changes of most intrinsic variables result either from pulsations in the star’s size (pulsating variables) or from interactions between members of a binary (twin) system. A few others do not fit into either of these main types. The only common type of extrinsic variable is the eclipsing binary. These consist of two close stars that periodically pass in front of each other as they move in mutual orbit. Algol is the most famous example. Eclipsing binaries account for almost 20 per cent of all known variable stars, with virtually all the remainder being intrinsic variables.
II PULSATING STARS
Of the stars that vary intrinsically in light output, the most common are pulsating variables. Probably the most famous examples are the Cepheid variables, whose regular pulsations provide a guide to their brightness, and hence act as important distance indicators in space. A related type are the RR Lyrae variables, which are commonly found in globular clusters. RR Lyrae stars are giants, less luminous than Cepheids, and vary by up to two magnitudes every day or so. Because they are at the same stage of evolution, they all have roughly the same luminosity and therefore make excellent distance indicators once identified. RR Lyrae stars are abundant, accounting for about 20 per cent of all known variables. By contrast, only about 1 per cent of known variables are Cepheids.
The most common variables of any type are the Mira stars, named after their prototype, the star Mira, or Omicron Ceti. These are red giants or supergiants with huge ranges in brightness (up to 11 magnitudes, a factor of 25,000 times) over timescales of months or even years. They are also termed long-period variables. Many other red giant and supergiant stars show some degree of variability, but much less pronounced than in the case of the Mira stars. Depending on the range of brightness and the degree of regularity (if any), they are classified as semi-regular or irregular variables. In all these cases, the variations are caused by fluctuations in the sizes and temperatures of the stars themselves.
III INTERACTING BINARY STARS
Some of the most interesting phenomena result from interactions between the two members of a binary system. The most spectacular examples are novae, in which a thermonuclear explosion occurs on the surface of a white dwarf star that has accumulated hydrogen from a close companion. Smaller but more frequent surges in brightness happen in the so-called dwarf novae (also known as U Geminorum stars). As in a nova, these consist of a white dwarf star and a normal companion, from which gas is dragged by the white dwarf’s gravitation. The gas forms a disc, called an accretion disc, circling the white dwarf. The outburst of a dwarf nova is caused by a brightening of the accretion disc, probably because of the release of gravitational energy from the inflowing gas.
In cases where one object in the binary is even more condensed than a white dwarf—that is, it is a neutron star or even a black hole—its gravitational field is so strong that infalling gas is heated to extreme temperatures and emits X-rays. The whole system is an X-ray binary, which can be observed by satellites in space. Variations in the intensity of X-ray binaries result from changes in the rate of mass transfer and from eclipses of the body emitting the X-rays, as in optical variables. SeeX-Ray Astronomy.
IV OTHER TYPES
Stars in the process of formation are also variable. T Tauri stars are very young stars with masses similar to that of the Sun. They show irregular variations owing both to activity in the stars themselves and to obscuration by dust clouds passing in front of them. Flare stars, also known as UV Ceti stars, are red dwarfs that undergo sudden jumps in brightness of up to 250 times, lasting only a few minutes. Flares similar to those on the Sun are thought to be the cause of the outbursts. Flare stars may be the next stage in evolution after T Tauri stars. R Coronae Borealis stars act in completely the opposite way. These are supergiants that occasionally fade by as much as eight magnitudes before slowly recovering. Such sudden fades are thought to be due to the ejection of carbon particles formed in the star’s atmosphere. Matter is also ejected by shell stars, fast-rotating stars that throw off gas from their equators, leading to a temporary dimming; Gamma Cassiopeiae is an example. The most spectacular variable stars of all are the supernovae, in which the star blows itself apart.
V NOMENCLATURE OF VARIABLE STARS
A specific system of nomenclature is laid down for variable stars. Those stars bright enough to have been given a catalogue designation already (such as Algol, which is designated Beta Persei) retained it when their variability was recognized. However, other variables were given a single- or double-letter designation in order of discovery, starting at R. Once all two-letter combinations have been used (that is, when 334 variables have been found in a constellation), the stars are given a number prefixed with the letter V, starting at V335
constellations
Tucana
Tucana (Latin, “the toucan”), southern constellation located south of Phoenix and north-east of Hydrus. Johannes Kepler called it Anser Americanus (“the American goose”) but this was superseded by the current name, which was introduced in 1603 by Johann Bayer. Its southern regions are notable for a large, bright globular cluster and the presence of the Small Magellanic Cloud.
Hercules (astronomy)
Hercules (astronomy), large constellation of the northern hemisphere, lying between Lyra and Corona Borealis. Hercules is best seen during the summer. It is represented by the figure of the Greek hero Hercules in a kneeling position. The stars of the constellation are of third magnitude or dimmer. Hercules contains a globular cluster, called Messier 13, consisting of more than 50,000 stars. This cluster, about 34,000 light years from the Earth, can be seen by the naked eye.
Virgo Cluster
Virgo Cluster, gravitationally-bound cluster of galaxies lying relatively close to the Local Group at a distance of some 50 million light years. The Virgo Cluster has an overall diameter of 9 million light years and contains over 2,000 galaxies, of which the largest are giant ellipticals. Several of the more prominent members are visible with small telescopes, and a number are included in the 1771 catalogue of nebulous objects compiled by Charles Messier. Among them, the central object M87 is notable as a particularly massive elliptical galaxy (containing 790 billion solar masses of material), from whose nucleus a jet of material is streaming. M87 is a strong source of radio emissions, known as Virgo A. Most members of the Virgo cluster are spiral galaxies.
The Virgo cluster is at the centre of a supercluster which includes our Local Group. Although the Virgo Cluster is moving away from the Local Group at a speed of some 1,140 km (700 mi) per second, both clusters share a common motion towards an unseen gravitational source known as the Great Attractor.
Delphinus
Delphinus (Latin, “the dolphin”), northern constellation, located to the west of Aquila and to the east of Pegasus, the main feature of which is a group of four bright stars that are known as Job’s Coffin. Delphinus also contains a number of fine binary stars, a variable star, and a very distant globular cluster. Most of its stars have a magnitude of 4 or 5.
Draco
Draco (Latin, “dragon”), northern circumpolar constellation situated between Ursa Major and Ursa Minor, just below the celestial pole. The star Etamin, Gamma () Draconis, a second-magnitude star and the brightest star in the constellation, was the principal object of measurement used by the British astronomer James Bradley in 1729 in discovering the aberration of light.
Hydra (astronomy)
Hydra (astronomy), constellation lying near the celestial equator. It is irregularly shaped and almost wholly made up of faint stars. It begins south of the constellation Cancer and extends eastwards nearly as far as the constellation Libra. Its long, winding shape was thought to resemble a water serpent. The constellation was originally recorded by the early Greek astronomer Ptolemy in his Almagest. The only bright star in the constellation is Alphard (“the solitary one”), actually a double star.
Serpens
Serpens (Latin, “serpent”), constellation in the equatorial region of the sky, best seen in the evening during northern summer (southern winter). It represents a large snake coiled around the constellation Ophiuchus, and is split into two halves, one part representing the head (Serpens Caput) and the other representing the tail (Serpens Cauda). It is the only constellation to be so divided. The constellation's brightest star is Alpha Serpentis, also known as Unukalhai (from the Arabic for “the serpent's neck”), magnitude 2.7. Serpens Caput, the larger half, contains the globular cluster M5, of the sixth magnitude and visible through binoculars. Serpens Cauda contains the Eagle Nebula, a cloud of glowing gas 7,000 light years away, containing a cluster of stars, M16.
what ever
the struggle
continue the climb
it maybe onlyyyyyyyyy
one step to the summit
dear piishii you can speak about every thing but in English!
hi vahed.
clear !
ok undrestood.
so let's start.
i recommend that say sentences like :
love is free bird.
be loving to those who love u
or anything that be short, pretty and has good information.
i nearly forgot , i know english more less than u
so if i have problems ,i beg correct me .
----------------
here is more sentences :
i adpted them from movies .
i love u enough for my heart to burn
it's raining.
the rain can't cool down my love for u
when i'm with u at night ot feels as if it were day
there is no worse death than the end of hope
what tomorrow brings we cannot know
Thanks a lot! welcome here...you are useful and you speak English good enough now you aren't all alone ha? enjoy
Could somebody tell me what's going on here? Are you here to talk about your ideas or ...? Don't you think you're actually barking up the wrong tree?
Dear Vahed
I've got a bone to pick with you!!! As you started this topic,I have to put most part of the blame on you. I don't know what you're after here. If it is practicing your writing, do you call copying some lyrics and texts of some news from other sites and pasting them here a way of practicing your writing?
For most of the posts you've put here, there are already some special topics. What you are doing here is just making a mess and a mishmash-a topic I myself don't know what to call: news section, literature hub, science center or what???
This is just a one-time request from all of you: Please stick to the title of the topic and keep making your posts about your ideas and thoughts. A good way of triggering a discussion can be putting forward a good & controversial topic and asking others to keep it going by sharing their ideas. RIGHT????
Otherwise the topic will be closed
Dear Reza as you know in fact this topic was (is & will) for speaking English and i really tried to kipping this but i had some requests for putting VOA news here so i did that! but you are right..i will re start speaking and tell it to everyone and i hope you will help me.نقل قول:
Hi every body
if you read dear reza's words you know whats wrong! i have a request, Please just say your own ideas ,your own texts and every words in your own mind and i will do that too! here is a topic for speaking English, just sharing your ideas and words.
thanks.
hey friends lets start again .i myself won't surrender and i don't like this topic be close so let's do it.
from the day i started learning english i promised to myself not to give up .i 'm eager to know how did you become enthusiastic to learn this beautiful language.let me know .
bbye my friends
نقل قول:
wow!such a great topic to talk about!well,it's a long story! l
I remember I started learning english when I was in grade 5 at primary school. In those days i really didn't know Y i want to learn English! after some time, I left it and after a year i started again. But this time, I myself liked to learn it. U know, I really liked to go to Canada! After that, our class became unisex, and there was a girl which was really gr8 in English! I never wanted to let her be better than me:D. So I did my homeworks regularly. And now, I'm not in the mood to go to classes. It makes me tired. But I'm still learning it at an institute. I just like English, that's Y I'm still continuing learning this language.l
hi i wanna tell my story that how i started learning english:
well, i strted learning english when i finished elementary school. first i really didnt like studing english you know i think teachers can be very influentional on learning things i mean teachers can make you intrested or even make you hate some thing well its my own opinion & when i started learning eng... my teacher made me disappointed but after one semester or so i became intrested in english & thats all...
hi dear vahed dont you want to talk about this topic or give us a new one well i think its not that bad to speak about ourselves dont you think so...
Dear Parnyan Yes! your answer is just yes........iam sad because of my works here because Reza is upset of me! but not matter i will start over i will begin it thank you
i start learning English since i was 12 at first i hat it because my free times was going over! but next by the time i felt in Love with it! really my love is English now........the best thing is learning English
ok,I am going to help it here to because I know how hard it is to make a topic stick on top here anad at the same time make every body chat in English We have the same problem in our own forums.
Hi dears from today we will start a new life in P30Forum its a new topic by the same name "Just speak in English" by our own English words ....i am righting a new text to share here with you! hope to enjoy it.

what has happened to you .we are all friends and we are not here to make quarrel.BTW,I haven' t been here for a long while because of some personal matters but i haven't forgotten you and this forum.oh let me welcome to the new member .i 'm glad you are interested too.so go on and help us
dear shahrzad you are right. we are all friends to make our life better! and....Happy Birth Day to you dear shahrzad!
thanks dear vahed .hey kids i had a question .who has read the book "davinci code".please tell me what do you think about it if you have read it .because i 'm going to download it .
cheers.
Dear shahrzad i read the Da Vinci Code its a good book and its about "Holey Maryam" and "isa masih"its forbidden in iran and other wheres i say read it! its interesting and good.and you can watch the Da vinci code movie!
dear vahed thanks a million.is there any one who has read this book.
dear vahed don't you get sad if i remind you some notes.you told me "holy maryam" but you should say "virgin mary" and also instead of"isa masih",you 'd better use "jesus christ" i hope you didn't get sad and i'm sure you knew these
bbye friends
hey friends what has happend here .i'm so sorry but i wanna be frank with you.with your silent you are just proving this fact that reza was right and this forum is nothing but a piece of junk.you make me disappointed.if you really love english justify your claim.
Dear Shahrzad yeah! its true ...thanks a lot for your notes...really i didn't know that words true English form. anyway thanks.
Hi Dear friends! where are you? we miss you here....come and speak English . every thing that you want...so start speaking. this topic needs you! please don't forget us and speaking English here!
HI Dear Vahed
well i my self really dont know what should i talk about. you told us talk about everything that we like but ...
could you please give us a topic. if you give us a topic i promise you to talk about that

hi vahed
it's a good topic but i have to say i have NO REAL FRIEND IN THIS BIG WORLD..every day i see two or maybe three girls around myself at school .although we know each other for more than seven years but i think that they don't know me and they can't understand me.i also used to have a great teacher who i thought was one of my friends but now... BTW, i still have to say i really admire him. he was a great teacher
well i ganna go bbye
thanks dear shahrzad....but you have lots of friends here now! hah? we all are your friends and you are one of our (at least my) best friends!
hi buddies
wow i think its a good topic for speaking & let me thanks dear vahed for giving us this topic .
well my best friend...i consider her very nice, clever,creative & outgoing& alittle naughty i think she has all the good adjectives that u think &she also has a good sense of human & one of the reason that we r so close is that we have a lot of in common in most of things like our hobbies &filed.
We live in a very big world with more than 10000000000000000 people but in fact nobody can tell that I'm not alone. people lives together but are alone:)
try to be friend with all if u want sweet life. life is too short, try to live
