We are running this course a final time this year for final examination in 2018. Take a look. The beneficiaries are the students involved in the course and the schools that participate in the partnership. If you stood at the equator (latitude 0°), the Pole Star would be right down on the northern horizon (declination 0°). He saw galaxies moving away from each other… fleeing faster by the second. If so, rearrange the formula accordingly. — The Great Bear (including The Plough). number of stars in our galaxy? I considered doing an astronomy degree at one point because I … – M31:  The Andromeda Galaxy I tutor all aspects of all 16 topics, as well as offering guidance for whichever of the projects are chosen. Pictured above is American astronaut, Colonel Alfred Worden — one of just 24 people to have flown to the Moon. Earth. It can also be glimpsed using a telescope fitted with a H-alpha filter. You can sign-up for the new version of the course, and gain the qualification by studying at home! What equipment is likely to be needed for naked-eye observing? Hey, This is Vignesh. In fact, the last one (The Plough) is not a constellation, but an ‘asterism’ — that is, a type of mini-constellation within a constellation. Mercury. What is Kepler’s First Law of Planetary Motion? Familiarity with Stellarium and the main concepts of the Celestial Sphere is required. Those near the equator return quicker. Well done if you noticed that this is 2.2 days longer than the orbital period (27.3 days). The above image shows the Leonid Meteor Shower, as photographed from space. It’s the afterglow of the Big Bang — the vast explosion that created our Universe. Feel free to snip, assign flipped learning tasks, or simply go over a lesson resource over two separate lessons. The rotation period is divided into 360 degrees (a full circle), with 1 full degree of rotation occurring every 4 minutes. – It provides air resistance, protecting us from most incoming meteoroids. Both solar and lunar eclipses can be determined years in advance, almost down to the moment they occur. A black hole exerts the same gravitational pull as the leftover core of the exploding star that created it. Venus Pure coincidence. — If you would like to study GCSE Astronomy, click the logo below to visit the website of the Online Astronomy Society Academy (OASA). There are 8 topics which need to be covered off. If you live in the northern hemisphere (as we do in Britain), at local noon, the Sun points directly south — that is, ‘due south.’  If you live in the southern hemisphere (as they do in Australia), at local noon, the Sun points due north. — Uranus As you can see (above), during a total lunar eclipse, the Moon does not vanish, but dims and takes on a red/copper appearance. What is the Moon’s rotational period, and orbital period? Code of Conduct Our Picks Clubs More In other words, a “shadow clock.”. Conversely, if you cube r, you’ll get the orbital period by requesting the SQUARE ROOT of the answer. Sundials display apparent (true) solar time. What is a “black hole?” — What does “stellar magnitude” refer to? The course consists of two units: Naked-eye Astronomy and Telescopic Astronomy. In the exam, you could be asked to label such a diagram, so do try to remember it. — its tenuous atmosphere; — reclining chair; The chromosphere extends to about 2000km above the Sun’s surface. Much more recently, in 1994, Comet Shoemaker-Levy 9 smashed into Jupiter with explosive results. Pearson Edexcel Level 1/Level 2 GCSE (9 - 1) in Astronomy (1AS0) Overview of topics: Topic 1 – Planet Earth You’ve probably guessed that this butterfly diagram is an over-simplification; they’re usually denser and more detailed than the one shown here. As you see, once the maximum point is passed, the number of sunspots declines. Topic 1. — What evidence supports that Planet Earth is approximately spherical? The video also discusses the celestial sphere, including the celestial co-ordinate system (right ascension and declination). As a result, we observe (almost) identical angular sizes — so one body can completely cover the other. — torch (red light to preserve dark-adapted vision); The vast majority of galaxies in the Universe are racing away from one another — fleeing faster by the second; never slowing for an instant. What does the term “mean Sun” refer to? Mountain-based observatories such as Hawaii’s Mauna Kea capitalise on this. Kepler’s three laws showed his master was wrong. GCSE Astronomy for Schools. How long does it take to orbit? However, due to Earth’s tilt and elliptical orbit, this varies during the year by up to 16 minutes either side of clock time. The reference in brackets after each In sum, dark matter surrounds and penetrates us, binding our galaxy together. Note that 1 parsec is equal to 3.26 light-years. What is a galaxy? What do galaxies look like? Once passed the chromosphere, though, temperature rises dramatically in the corona. A megaparsec is one million parsecs — bearing in mind that a single parsec is 3.26 light-years. That’s why stars form anti-clockwise circles around the Pole Star. They appear large, flat, smooth and dark-grey in colour. Edexcel GCSE Physics Revision made by expert teachers. I’ll never forget my first view of a solar flare through a H-alpha filter. Note:   The GCSE Astronomy syllabus is changing from September 2017. Even if the polar caps aren’t to blame now, they will be eventually if our planet keeps getting warmer. Just as a few galaxies near to our own have formed the Local Group (due to their mutual gravitational attraction), so if we look much farther out, we see that galaxies clump together on a grander scale to form ‘clusters.’  The Virgo Cluster is the nearest galactic cluster to us.
