GCSE ASTRONOMY COURSEWORK CONSTELLATIONS

So fast, in fact, that they cannot resist slamming together to form entirely new atoms. It is debatable whether galactic clusters and, indeed, superclusters will drift apart over time, overcoming their mutual gravitational attraction, or meet in the middle with a catastrophic crunch. There are eight planets in our Solar System, or nine planets if you still count Pluto. Hence, lunar eclipses occur more frequently. Exoplanets are popping-up everywhere and often.

What is the typical composition of a comet? I glanced up and was surprised to see many stars concentrated in a line. Earth also lies tilted on its axis by In astronomy, though, the parallax effect is used to gauge the distance to the stars albeit imperfectly. This is in two main parts:

However, this is beyond the scope of GCSE.

By that time, thousands of sailors had perished at sea due to an inability to determine their east-west position. Consequently, sizzling jets of matter and radiation are blasted outwards in a continuous stream — ejected from above and below the black hole.

In physics and chemistry, we are taught to avoid the parallax effect as this can lead to false measurements. Based on current knowledge, life depends on water for its existence.

Long-period comets are those taking more than years to complete one orbit, while short-period comets take less than years.

A solar day is noon to noon, just as a synodic month is New Moon to New Moon. This could be due to the enormous gravitational pull exerted on the star by itself — crushing it out of existence before aastronomy outward explosion has time to occur.

Thankfully, Earth has far fewer volcanoes and is much less volcanically active. What are the possible consequences of a PHO impact?

In summary, the atmosphere of Venus illustrates what can happen to an Earth-like planet if the greenhouse gas level soars. To date lateover exoplanets are confirmed to exist, and the number keeps rising.

A basic working knowledge will suffice. Here are the 24 letters of the Greek alphabet, and how to pronounce them:.

Conversely, if our local noon comes four minutes before theirs, then the opposite applies: Hence, the Moon does spin, but slowly; keeping the same side to us as it encircles our world. The circles radiating outwards are trails of light formed by other stars during the night.

What equipment is likely to be needed for naked-eye observing?

Exoplanets are popping-up everywhere and often. Hence, the ecliptic is an orbital plane shared by all the planets of our Solar System, and it lies within the Zodiacal Band. This site uses constellationz.

This suggests that Venus was once extremely volcanically active. But how can you tell e.

The minimum coincides with the start of a cycle. It takes light from our next nearest star four years to reach us… travelling atmiles per second! Then proof from outer space when Galileo came along! This is the maximum point. But is there a way to tell whether any other stars are circumpolar? It contains around galaxies, all orbiting a common centre of gravity located around 15 to 20 megaparsecs from here. You could be asked to label these features in consfellations exam.

Basically, a cousrework wavelength indicates a blue-shift galaxy coming towardwhereas a long wavelength indicates a red-shift galaxy moving away.

Note that, in fact, every comet sprouts two tails as it approaches the Sun: This may seem like a complex way to determine stellar distances, but we cannot extend a tape-measure to the stars! A proton is a positively charged particle. This is a paradox, since the similarities with Earth are highly unlikely to be a coincidence. It says that your personality and future can be predicted according to which star constellation happened to lie behind the Astronomu on the day you were born.

Hence, large mirrors in reflectors are preferable to large lenses in refractors.
