It shows that Juliet and Romeo were destined to be just as it says in the Prolauge
The comparison to stars in Romeo and Juliet serves as foreshadowing because it suggests that Romeo and Juliet's love is destined to be powerful but also doomed, mirroring the tragic fate of stars that burn brightly but eventually perish. This imagery hints at the eventual tragic outcome of the lovers' story, where their love ultimately leads to their deaths.
Metaphor. Here's an example: Her eyes were bright stars shining in the darkness. This is an example of a simile, which is the opposire of a metaphor (uses like or as): Her eyes were as bright as stars shining in the darkness. or Her eyes were bright, like stars shining in the darkness.
A metaphor is an implied comparison between one thing and another for literary effect. If the comparison dwells on multiple areas of comparison, it is an extended metaphor. "In the night sky of her face, her eyes were stars beneath the windblown rainclouds of her curling hair."
In a metaphor, the object is the thing being compared to the subject. It helps create a vivid image or comparison in the reader's or listener's mind. For example, in the metaphor "Her eyes were stars," "eyes" is the object being compared to "stars."
No, foreshadowing is not a theme. It is a literary technique often used to draw out theme, in which you hint at possible things to come. It can be as clear as The Scarecrow (or he who is to become the scarecrow) singing "life's more painless for the brainles" (From Wicked! the musical) or as subtle as one person's movie ending before the other's (The Fault in Our Stars by John Green, YA novel). Steinbeck uses a lot of foreshadowing in Of Mice and Men, for example, the death of Candy's dog to foreshadow the death of Lennie. So yes, it often goes hand in hand with theme, but no, foreshadowing itself is not a theme.
The hottest stars are the blue stars, the blue hypergiants in particular. One example is "R136a1", which is a blue hypergiant that has estimated surface temperatures of over 40,000 Kelvin (well over 70,000 F). Our Suns effective temperature is around 5,700K for comparison.
They are star systems comprising three stars which are orbiting one another. A notable example is Polaris.
Gemini
For example, if you live at a latitude of 50° north, the circumpolar stars will be all stars that are up to 50° around the celestial north pole. As another example, if you live at a latitude 30° south of the equator, the circumpolar stars will be all those that are in a circle up to 30° around the celestial south pole.
A simile is a comparison of two ideas or objects, usually using like or as. Her nose is LIKE a waterfall, always running. Her teeth are LIKE stars, they come out at night. A metaphor is a comparison when one thing is said to BE the other, and is not just a comparison. Her nose IS a waterfall, always running. Her teeth ARE stars, they come out at night.
Red Dwarf stars are the commonest in the Galaxy. Red Dwarf stars last much longer than blue stars for example. So you would expect to find more of these red stars. You need a telescope to see them, but they are very common.
