It’s important for you to realise that “star trails” are due to our planet spinning on its axis. What methods attempt to prove the origin of water on Earth? It means that a galaxy is moving away from us. — Exoplanets, or “extra-solar” planets, are those found outside our Solar System, orbiting stars other than our Sun. To recap, Kepler’s laws tell us:  (1)planets orbit the Sun in ellipses, with the Sun at one focal point; (2)planets orbiting the Sun sweep out equal areas in equal times; (3)all planets orbiting the Sun are related by a number, known as a “constant” — although you’re not required to calculate this at GCSE. In other words, if you time a planet going around the Sun, it matters not whether that planet is close to the Sun (so moving fast) or far away from the Sun (so moving slow), it’ll always cover a fixed amount of area within a fixed amount of time. After a few seconds, switch to the other eye. How does the Sun’s rotation period vary? Astronomy GCSE In the 2003/2004 academic year I taught an Astronomy for GCSE evening course as part of the adult education classes at Barton Peveril College, Eastleigh, Hampshire.The online notes for the course are kept here as a historical reference. How is the Sun’s energy generated? FREE (0) Popular paid resources. Long-period comets are those taking more than 200 years to complete one orbit, while short-period comets take less than 200 years. GCSE Astronomy doesn’t require knowledge of these men’s lives, including the insurmountable odds they sometimes faced in convincing others. What are the different lunar phases? Coursework notes. Here are the links to our revision notes for GCSE subjects. Basically, it’s to do with Earth’s orbit around the Sun. By that time, thousands of sailors had perished at sea due to an inability to determine their east-west position. But it highlights yet another piece of compelling evidence:  the existence of different time zones. To date, most of our Solar System exploration has been via space probes, landers and robotic rovers. This is because, at the same time as being orbited, the Sun is falling towards the centre of our galaxy — thus orbiting it. Asteroid Hunting. How do cometary orbits differ from planetary ones? It sent back lovely, close-up images of the comet in the hours before impact. From stars and constellations, the solar system and nebulae; to cosmology and space exploration; our interactive GCSE Astronomy online course will enable you to explore space through engaging resources, at your own pace.. GCSE Astronomy Version 2012 Controlled Assessment Teacher Support Book 2 Overview of assessment There are two units in GCSE Astronomy, with the same assessment weighting as in the previous specification. In other words, a “shadow clock.”. — Then, as the wobbling star draws away from Earth, its light becomes red-shifted by a tiny, yet noticeable, margin. It’s the afterglow of the Big Bang — the vast explosion that created our Universe. Quoting from the most recent edition of my GCSE textbook: “These methods have been successful at detecting massive exoplanets similar to Jupiter, but have yet to provide convincing evidence for the presence of Earth-like worlds with much smaller masses.”. In fact, the true value is 40,075km… remarkably close. Work Sheet 1. Instead, be prepared for a tiny bit of maths! Earth takes 24 hours to complete one full revolution of 360 degrees, so one hour marks one twenty-fourth of its spin — or 15 degrees’ longitude.”. That record is held by Venus, the second planet from the Sun. At the North Pole, you’d see the Pole Star directly overhead. You may be relieved to know that a full understanding of the (quite mathematical) Third Law is no longer required for GCSE Astronomy. This extreme heat causes atoms of hydrogen within the core to whizz around… fast! She was napping on her couch (wrapped in blankets) when a meteorite suddenly burst through the ceiling and struck her in the thigh. Short Talk on Dark Matter. — This is due to a 5° tilt in the Moon’s orbit, making perfect Sun-Moon alignment a rare event. As you can see, there’s a close symmetry between the top/north half of the diagram, and the bottom/south half. — small table; Mrs Hodges kindly donated it to science. But aided, we mean, with a telescope. After noon, the shadow will start to grow again. I advise watching the supplementary video, which provides useful commentary. – It absorbs X-rays and gamma rays from outer space. The vast majority of galaxies in the Universe are racing away from one another — fleeing faster by the second; never slowing for an instant. I glanced up and was surprised to see many stars concentrated in a line. Venus has many more volcanoes than Earth. He wrongly designated some stars brighter than others, and failed to give some stars a designation at all. Now, whilst astrology is considered bunk to most scientists, the zodiac does have a use for astronomers:  it establishes a tidy path for the Sun and other planets to travel along. — because the Moon doesn’t rotate at all, as many people believe. – Aeroplanes fly in arcs, not straight lines, as arcs are shorter over curved ground. This point is known as the ‘radiant.’  Depending which constellation the radiant is closest to will determine the name of the shower.
