ASTRONOMY GCSE COURSEWORK CONSTELLATION DRAWINGS

In fact, or-so galaxies are positioned close enough in space to feel the combined gravitational pull of one another; hence, instead of racing apart, these few the Local Group are slowly coming together. Not bad for a simple experiment with sticks, conducted over years ago! An indirect method of observing the Sun is safest. We know that some galaxies in the Local Group are destined to collide because, when spectroscopically analysed, their light reveals a blue-shift — i. And that was on a short trip to the Moon, so a Mars mission lasting over a year could take a hard toll on the crew. It also covers the inverse square law of light intensity, and explains what a Cepheid variable star is.

To see a video about rearranging formulae on the Maths Tidbits page, Click Here. What steps are humans taking to explore planets and other bodies? But what could it be, exactly? Thus, an extra precaution is needed. I myself have seen it once — in rural Pennsylvania.

What are galactic clusters? In our Solar System, the biggest thing of all is the Sun; hence, it exerts the strongest gravitational pull, causing everything else to orbit it. She was napping on her couch wrapped in blankets when a meteorite suddenly burst through the ceiling and struck her in the thigh. If Kepler and Copernicus can be credited with disproving the geocentric model in theory, Galileo Galilei ought to be credited with disproving it in practice.

At noon on the Summer Solstice 21 st Junewith the Sun at its highest in the sky, Eratosthenes and sstronomy friend each measured the angle of the shadow cast by their stick.

Pick an object in your room. How can the Hubble Constant determine the age of the Universe?

The following are examples of circumpolar constellations; i. A basic grasp is all you need to do well. This is why a neutron star is so named. Therefore, you can also tell whether a star is circumpolar by using a simple maths trick:.

Lunar eclipses do not occur at every Full Moon, for the same reason that solar eclipses do not occur at every Coursewirk Moon. In fact, the true value is 40,km… remarkably close. According to science writer, Dava Sobel, in her popular book Longitude:.

Sailing down from the North Pole, the Pole Star would get lower and lower in the sky. In the above image, each triangle represents a measurement of green area as covered by the planet in a fixed period.

Hence, a pattern of regular shifting blue-to-red and back again would strongly suggest the presence of a planet — tugging on the star as it goes around. What is the origin of the lunar craters and seas?

However, an observer on the ground must know where about in the sky to look. You could watch the sky, of course, and stars or constellations that never set would consteloation circumpolar.
