Astronomy for Beginners
Astronomy for Beginners
This was originally an online group which ran from January until April 2021. Many of us would like to know more about our planets, the stars - and the universe. So I suggested some things we could do each week, and information about this and all the resources are shown below. Although this weekly structured part of our learning has finished, this will remain on this webpage indefinitely, and you can either follow this in your own time or just dip in to explore what interests you most. and if you have any comments or suggestions about any of this, or if you would like to become group organiser and arrange for members to meet in a group , please get in touch with me.
I also feature a section called 'Further resources and your suggestions' where I can add more resources and some topical issues in the future if you would welcome this. This is a subpage of this webpage, and so you can get to it by clicking or tapping on the arrow next to the Astronomy tab in the main menu, or just click or tap here: Astronomy - Further resources and your suggestions

Week 1 - Introduction, an online course and The Planets (part 1)
Watch the video of the week, which is the BBC programme “The Sky at Night – a Beginner’s Guide”. Click or tap here to view it - https://www.youtube.com/watch?v=rFTw4W8A_vc&ab_channel=NikolMizer. I strongly recommend this an excellent introduction. It is just 29 minutes long, and the last 9 minutes are about telescopes which may not be of interest to you at this stage anyway. So at 20 minutes it’s a good watch.
Reading: ‘Universe: The Definitive Visual Guide’, edited by Martin Rees (the Astronomer Royal) and published by DK. This has a great deal of detail and some dazzling graphics. See https://www.amazon.co.uk/Universe-Definitive-Visual-Guide-DK/dp/0241412749. The relevant section this week is 'A short tour of the Universe (pages 8-19)
Look at the website of the week, which links in with the video. It’s the Sky at Night website. There is a lot of interesting stuff here – including Pete Lawrence’s guide to finding constellations in January (we will be returning to constellations later). Click or tap here - https://www.bbc.co.uk/programmes/b006mk7h
Learning of the week: Start a free online course – The Future Learn / Royal Observatory Greenwich course “Our Solar system and Beyond: Teaching Primary Science”. It’s a three-week course (approximately three hours study per week), and Week 1 is “Tackling Scary Science”. It is pitched at primary school teachers, and so it should provide a different and stimulating way at looking at the basics. You can enrol immediately on this free course by clicking or tapping here: https://www.futurelearn.com/courses/primary-science
As a bonus, watch a second video of the week. It’s a great performance of Gustav Holst’s ‘The Planets’ by the BBC Symphony Orchestra at the Barbican 100 years after its composition. Professor Brian Cox introduces each movement (a sort of mini-lecture) against the backdrop of the very latest in stunning planetary imagery. Science meets the arts! Click or tap here to see a version of this which someone has posted on YouTube at https://www.youtube.com/watch?v=kAMwWrL-edA&ab_channel=ACFerrad
Week 2 - The Planets (part 2)
Videos of the week: The BBC2 daytime programme schedules have been changed this week, and all this week Professor Brian Cox’s excellent series on ‘The Planets’ was broadcast every day in January on BBC2. This week we are concentrating on the largest planet in our solar system - Jupiter - and the programme on Wednesday is ‘The Godfather: Jupiter’. If you didn’t see it as it is broadcast, click or tap link here https://www.bbc.co.uk/iplayer/episode/p06qj30b/the-planets-series-1-3-the-godfather-jupiter to see it on BBC iPlayer website or on the iPlayer app. And the other four programmes in this series are on this link here https://www.bbc.co.uk/programmes/p07922lr/episodes/player
Reading of the week: ‘Our Solar System’, a free 42-page booklet published by NASA as a PDF which gives a lot of detail about the sun and all the planets. You can read this and/or download it by clicking or tapping on this link: https://www.nasa.gov/sites/default/files/files/Solar_System_Lithograph_Set_h.pdf. As it’s a PDF, I find the best way to read it is on an iPad (download it to iBooks) or on another tablet (download to a PDF reader). Thank you Maurice for recommending this very useful reference booklet.
Additional reading: ‘Universe: The Definitive Visual Guide’, edited by Martin Rees (the Astronomer Royal) and published by DK - https://www.amazon.co.uk/Universe-Definitive-Visual-Guide-DK/dp/0241412749. The relevant section this week is the planets section of 'The Solar System' (pages 98-209).
Online learning - The Future Learn / Royal Observatory Greenwich course “Our Solar system and Beyond: Teaching Primary Science”, a three-week course (approximately three hours study per week). Week 1 (“Tackling Scary Science”) was rather good and covered perceptions of science and explaining scientific concepts (with an excellent basic video on ‘Space Rocks’) and some trusted sources (which we will return to in the weeks ahead). We start Week 2 this week, which is about teaching astronomy, and it looks as if there will be some more interesting videos coming up. You can enrol immediately on this free course by clicking or tapping on this link here: https://www.futurelearn.com/courses/primary-science
Week 3 - The Sun
Our focus in the first two weeks has been on the planets, and I hope you have enjoyed the recommended programmes in particular. This week we turn our focus to the Sun.
1. Videos of the week on the Sun (I recommend viewing them in this order):

3. Online learning: The Future Learn / Royal Observatory Greenwich course “Our Solar system and Beyond: Teaching Primary Science”, a three-week course (approximately three hours study per week).
Last week, Week 2 (‘Teaching Astronomy and Going off-curriculum’) was, I thought, excellent. There were very clear short videos on Day and Night, Phases of the Moon, Seeing the invisible, The Big Unknowns, How will the World End, and Scientists Investigate. There was also a great audio on Challenging Questions - how to answer difficult and impossible questions, with some great suggested answers!
We start the third and final week now, which includes Real Science, Real Scientists and Real Data, plus external resources. It should be good. Is anyone else doing this at the same time as me?

Online learning:
The Future Learn / Royal Observatory Greenwich course “Our Solar system and Beyond: Teaching Primary Science”, a three-week course (approximately three hours study per week). You can sign up any time, and once you have signed up you have a further two weeks to complete it (i.e. five weeks altogether). So it’s not too late to sign up now. You can enrol immediately on this free course by clicking or tapping on this link - https://www.futurelearn.com/courses/primary-science
Week 3 was the final week of this course if you started this at the beginning of the month. This included Real Science, Real Scientists and Real Data, plus external resources. Has anyone else been doing this?
Week 5 - Review, and new online course
We are now on to Week 5 of our Astronomy for Beginners activities. I’m aware that there has been a lot of information to absorb so far, and all of the material about the planets, the sun and the moon will stay on our webpage for you to look at in your own time.
Review of what we have learnt so far
As we have come to the end of our first month, I suggest that we have some time this week to reflect on what we have learnt over the past four weeks about the planets, the Sun and the Moon. There have been a lot of resources, and so some of us may need some time to catch up! I hope you found the suggested activity for the first four weeks useful and interesting, and as you know I have put all of these resources on this webpage so that you can refer to them in future, and they will remain there indefinitely.
Online learning: ‘Astronomy with an Online Telescope’
Having completed the Future Learn / Royal Observatory Greenwich course “Our Solar system and Beyond: Teaching Primary Science”, we can now move onto another free online course which will take us through to Easter.
The online course which I am recommending is called ‘Astronomy with an Online Telescope’ and is offered by the Open University. This sounds very exciting, and here is part of the description: “This free course, Astronomy with an online telescope, shows you how to navigate the night sky, and introduces the wide variety of objects it contains. You will develop a hands-on understanding of telescopic observations using the Open University’s own robotic telescope facility COAST sited on the island of Tenerife. Supported by your own measurements we illustrate how stars evolve, and study variable stars.”
You can see a short video and find out more about it, and sign up if you wish, from this link https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview. The course is spread over eight weeks which will take us up to Easter, and involves about three hours of study per week. More detail on the eight modules is on this link: https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview?active-tab=content-tab. You can start this course right now without signing-up, but if you want to be able to track your progress, earn a free Statement of Participation, and access all course quizzes and activities, you can sign up free.
So this week, I am suggesting that we do the first module of this course which is ‘Week 1: The Night Sky’: https://www.open.edu/openlearn/ocw/mod/oucontent/view.php?id=74591.
“In this first week of the course you will start to find your way around the night sky with the aid of a powerful software package called Stellarium. This is a free-to-use program that provides a detailed representation of the night sky as seen from any location in the world. Using this software you will be able to identify the patterns of the constellations, understand the apparent movement of the sky with the seasons and throughout the night, and use the system of celestial coordinates to find and specify the position of individual objects in the night sky”.
Week 6: Software, websites and apps for stargazing
This we week we are exploring some great free apps.
Stellarium
Those of you who did the FutureLearn / Royal Greenwich Observatory online course last month will have been introduced to Stellarium in Week 3. This featured in a video which was about looking for Jupiter but covered wider aspects, and you can see this video and download some free PDF guides to Stellarium at https://www.rmg.co.uk/schools-communities/learning-resources/looking-jupiter-0. The direct link to the 3-page guide is https://www.rmg.co.uk/sites/default/files/KS4%20Looking%20for%20Jupiter.pdf. Stellarium is also the software that is recommended by the Open University in the ‘Astronomy with an online telescope’ online course (see below).
You can see the Stellarium website and download the Stellarium software to your computer free (Windows, MacOS and Linux) at http://stellarium.org/. Or you can download the app to your smartphone or tablet free from the Apple app store or Google Play app store.
Celestia
Last month’s course also introduced us to Celestia which is a free spaceflight simulator which lets you explore space in 3D, and its website is on this link: https://celestia.space/. An 8-page guide to the use of Celestia applied to Jupiter as an example is at https://www.rmg.co.uk/sites/default/files/import/media/pdf/KS3%20Celestia%20Navigation.pdf. There are more comprehensive guides at https://celestia.space/guides.html. You can also download this software to your computer from the Celestia website (Windows, MacOS and Linux), or it is available as an app for your smartphone or tablet from your usual app store.

Online learning: ‘Astronomy with an Online Telescope’
I mentioned last week the next online course which I am recommending which is called ‘Astronomy with an Online Telescope’ and is offered by the Open University. You can see a short video and find out more about it, and sign up if you wish, at https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview. The course is spread over eight weeks which will take us up to Easter, and involves about three hours of study per week, and you can start from Week 1 any time (some of us started last week). So if you started this last week, the next module of this course is ‘Week 2: Telescopes and visual observing’: https://www.open.edu/openlearn/ocw/mod/oucontent/view.php?id=74591.
Week 7: Asteroids
This week’s topic is all about asteroids - and how what happened 66 million years ago changed everything on earth. This subject was prompted by an excellent Exmouth u3a Zoom talk we had from Dr Daniel Field at Cambridge University at our Connect on Thursday meeting last week on the evolution of birds (see https://www.cam.ac.uk/stories/wonderchicken if you are intrigued!),

We are now in Week 6 of the online course ‘Astronomy with an Online Telescope’ offered by the Open University (details on this link: https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview). The course is spread over eight weeks, and you can start from Week 1 any time.
The Week 6 module is Classifying the Stars: ‘This week, you will continue to explore the relationship between the colour and luminosity of stars, finding that the colour of a star depends on its temperature and that there is a correlation between temperature and luminosity. Plotting these two properties against each other produces the Hertzsprung-Russell diagram – one of the most famous diagrams in astronomy. You will explore this diagram and find out what it tells us about the lifecycles and eventual fate of the stars’. Link here: https://www.open.edu/openlearn/ocw/mod/oucontent/view.php?id=76152
Week 11: The Constellations
This week our topic is on the stars and the constellations - a group of stars that forms a particular shape in the sky and has been given a name.

Online learning: ‘Astronomy with an Online Telescope’
We are now in Week 7 of the online course ‘Astronomy with an Online Telescope’ offered by the Open University (details on this link: https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview). The course is spread over eight weeks, and you can start from Week 1 any time.
The Week 7 module is Variable Stars: ‘This week we will look at how stars evolve once their main sequence lifetime comes to an end, and in particular at the instability strip on the HR diagram and the reasons why some stars become variable at certain stages in their lifetime’: Link here: https://www.open.edu/openlearn/ocw/mod/oucontent/view.php?id=76344
Week 12: Black Holes
This week, by popular demand our topic is Black Holes - ‘a compact region of space, surrounding a collapsed mass, within which gravity is so powerful that no material object, light, or any other kind of radiation can escape to the outside Universe’.

Online learning: ‘Astronomy with an Online Telescope’
We are now in Week 8, the final week, of the online course ‘Astronomy with an Online Telescope’ offered by the Open University (details on this link: https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview). The course is spread over eight weeks, and you can start from Week 1 any time.
The Week 8 module is ‘Building a Light Curve’: ‘This week you will retrieve the images acquired by COAST and use the information from these to select the best exposure when requesting further images. You will learn how to identify your target star in your images and how to measure the brightness using an online aperture photometry tool. Provided the weather is clear you may be able to get images from several different nights and start to see the variation in brightness in your own observations.’ Plus there’s an opportunity to collaborate with others on this.

Week 13: The Future of the Universe
This week, it was suggested that we should look to the future, and so our topic is The Future of the Universe – the Big Crunch, the Big Chill, the Big Rip and Dark Energy. But please don’t get too upset by this, as this will not be happening for some considerable time!

Online learning: ‘Astronomy with an Online Telescope’
Although we have reached Week 8 (the final week) of this online course, you can go at your own pace – and you can start this at any time. It’s offered by the Open University (details on this link: https://www.open.edu/openlearn/science-maths-technology/astronomy/astronomy-online-telescope/content-section-overview).
Week 14: The Future - Space exploration and space flight
What’s happening in the sky at night
The BBC Sky at Night website is always worth keeping a watch on for any older programmes you haven’t seen or any new programmes that are broadcast in the future: https://www.bbc.co.uk/programmes/b006mk7h. On that website is a brief star guide on what is happing in the sky each month.
It is also worth taking a look at the BBC Sky at Night magazine. This gives details of what is happening in the sky on most nights for each month, together with monthly highlights for the Moon, the planets, comets and asteroids, plus a star map for the month. I have just discovered that you can see each edition online free (plus 200 other magazines!) via the Libby app if you are a member of Devon Libraries This may also be available through other public libraries in other parts of the country. Further information is on this link https://www.devonlibraries.org.uk/web/arena/emagazines and https://devon.rbdigitalglobal.com/search/emagazine?page-index=0&page-size=60
Here is my suggested action for our final week on the topic of ‘The Future – space exploration and space flight’
