March 04 – Messier 85

1781  –  Messier 85, a lenticular (elliptical if you prefer) galaxy, was discovered on this day in 1781 by Pierre Méchain.  It can be found in the constellation Coma Berenices (named after the Egyptian queen Berenice II) and is about 60 million light years away, making it the northernmost galaxy in the Virgo Cluster, a collection of somewhere between 1,200 and 2,000 galaxies, on the periphery of which is our own local group.

There are hundreds of beautiful photographs of all manner of galaxies on the internet, but M85 is very under-represented by legal entities with relaxed media sharing policies, hence the above.

1861  –  Asteroid 64 Angelina discovered from Marseilles by Ernst Tempel.  Angelina is an E-type (containing enstatite) with a very high albedo (0.28) compared to many other asteroids.  It is named after an astronomical station operated by the Hungarian astronomer Franz Xaver von Zach.  For discovering Angelina (and 65 Cybele) Tempel received the ‘Lalande Prize’ from the French Académie des sciences.

1892  –  M-type (mainly metallic) main belt asteroid 325 Heidelberga was discovered today by Max Wolf.  If you’ve been following these pages closely the choice of name should come as no surprise, being the location of most, if not all, of Wolf’s discoveries. Heidelberga is reasonably large, at approximately 75 km in diameter.  Fuller details of Heidelberga’s physical and orbital characteristics can be found in the NASA JPL Small-Body Database browser.

1904  –  Birth of George Gamow, cosmologist, and early champion of the Big Bang theory.

1923  –  Birthday of Patrick Moore, amateur astronomer extraordinaire.

December 09 – Patrick Moore

There’s not a lot I can say that hasn’t already been said a hundred times or more about this chap, but it’s four years today since the passing, at the age of 89, of Sir Patrick Alfred Caldwell-Moore CBE, FRS, FRAS, singleton, leg spinner, xylophonist (if that’s the right word), RAF veteran, composer, cat lover, EEC hater, star of The GoodiesThe Morecambe and Wise Show and GamesMaster, general legend, and best all-round entertainer since Daffy Duck.  And it appears from the photograph that he also may have owned a telescope.

I’m not sure where I got that signed photograph from, but it lives inside my copy of Mrs Moore in Space, by Patrick’s mother, Gertrude.

I briefly met him a few times, donkey’s years ago: two of these were at speeches he was giving in the environs of North Staffordshire and South Cheshire, where I was restricted to standing in line waiting for an autograph, and twice were a little more informal at book signings I was involved with in my previous life as a bookseller.  I’d like to say how many books Patrick Moore wrote, but I’m not entirely sure they can be easily counted, as they stretch over such a long period, and had such wildly varied life spans.

To end on a sour note: it’s pantomime season, so boos and hisses to Macmillan publishers, who decided in 2016 to cease publication of “Patrick Moore’s Yearbook of Astronomy”.  Remind me to never buy any of their books again.

1892  ⇒  Discovery of the large main belt asteroid 349 Dembowska by French astronomer Auguste Charlois.  It was named in honour of the Italian astronomer Baron Ercole Dembowski, a specialist in double stars (and if the name sounds less than Italian, it’s because his father was a Polish general).  349 Dembowska is about 140 km wide, and is one of the brightest of the large asteroids.  It is classified as R-type, characterised by spectral lines showing the presence of olivine and pyroxene (the main constituents of the Earth’s mantle), and possibly plagioclase feldspars.
