M2 (aka NGC7089) is one of the largest and oldest globular clusters known. It can be found in the constellation Aquarius and is 37500 light years from Earth.
The cluster of stars is 17.5 light years in diameter and is estimated to contain 150,000 stars.
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.
