We have had a flurry of new subscribers over the past couple of weeks, so welcome everybody to our 2020 blogs. We now have over 100 subscribers which is very exciting and we feel it is time to write our first blog for 2020. Today is the 30th anniversary of the famous pale blue dot photograph taken by Voyager 1, an Earth selfie taken from almost 4 billion miles away. This image, its significance and the story behind it has featured in just about all of our lessons this week.
