The early Universe had hydrogen and helium, but no metals (heavier elements). Metals were produced by fusion in stars; in the case of a supernova, significant amounts of those metals get out of the star, and participate in the formation of future solar systems.

Where is the earth on the star life cycle?

The "star life cycle" refers to stars. Earth is not a star.


Where is earth currently in its precession cycle?

Earth is currently in its precession cycle, with the axis slowly wobbling like a spinning top. This cycle lasts about 26,000 years and affects the orientation of Earth's axis with respect to the stars.


Why does it seem that the sun and the stars move across the sky?

The apparent movement of the sun and stars across the sky is due to the rotation of the Earth on its axis. As the Earth rotates, it gives the illusion that the sun and stars are moving across the sky from east to west. This movement is responsible for the cycle of day and night.


When esimating the distance of the stars from earth astronomers use the fact that nearby stars shift in position as observed from earth which is called?

Nearby stars appear to change their position against the distant background in an annual cycle, because of the Earth's changing position 'across' its orbit. This apparent shift is called the star's "parallax".


What information does the color of a star provide?

The color of a star provides information about its temperature. Blue stars are hotter than yellow stars, which are hotter than red stars. This color-temperature relationship helps astronomers understand the life cycle and characteristics of stars.


Why is it important to know the life cycle of stars?

Understanding the life cycle of stars helps us comprehend the universe's evolution and the elements present in it. It also provides insights into how galaxies form and evolve. Additionally, knowledge of star life cycles aids in predicting supernovae events and the creation of black holes.

How long does it take the moon to orbit the earth in one cycle?

Viewed against the background of distant "fixed" stars, the moon completes one orbital revolution in 27.32 days. Observing the "phases" of the moon from Earth, it displays a complete cycle of shapes every 29.53 days.


How the earth is affected by stars?

earth is effected by the stars because they are to bright


How long does it takes the moon to orbit the earth in one complete cycle?

Why is there sometimes just a moon no stars?

Different constellations, groupings of stars, are visible during different points in the earth's elliptical cycle. So, on some nights, the angles between the stars and earth do not allow for a good view of certain constellations. Another factor in visibility of cosmic structures is the fact that the moon is considerably larger and closer than many stars. Light pollution also accounts for obscuring the view of many stars and constellations.
