M19 (aka NGC6273) is a globular cluster in the constellation Ophiuchus which is just visible with binoculars. It is approx 28,000 light years from earth relatively close to the galaxy centre. It is made up of a number of different stars and has a mass approx 1 million times that of our Sun.
I am semi-retired after a career in medical sciences. I now work from home doing independent research and consultancy amongst other things. One advantage of this is that I do have time to indulge my interests including birdwatching, natural history, steam trains and history particularly ancient history.
