"An asterism is a word used to describe a pattern of stars visually recognisable from the Earth. An 'asterism' although similar to a 'constellation' differs in that a 'constellation' is an officially recognised area of the sky. asterisms come in all shapes and sizes from small to large. The 'Summer Triangle' is a very large asterism,  a triangular pattern of three 'alpha stars' taken from three separate constellations:  Deneb from Cygnus the Swan,Vega from Lyra the Lyre and Altair from Aquila the Eagle. In the 1950s the 'Summer Triangle' was popularised by the American author Hans Augusto Rey and the British astronomer, author and television presenter Sir Patrick Moore". - Archie Mendes - visiting theoretical astronomer at the Jodrell Plank Observatory - Reydon University - 'School of Computer Modelling and Difficult Sums'

"The above images were taken on the 13th August 2018 from beside Windermere in the Lake District. I was trying to photograph Perseid Meteors but although I managed to see  10 or more over three hours of observation, none were evident on the the many frames captured by my camera. The night skies in the Lake District were very dark but the weather and levels of condensation I experienced made me very happy to return to Lowestoft on the East Coast". - Kurt Thrust acting CEO and current Director of the Jodrell Plank Observatory.

"NGC1964 is the main galaxy in the NGC1964 Group. It is approximately 100,000 light years across and is some 65million light years distant in the constellation Lepus the Hare. At the centre of the galaxy is a super massive black hole with an estimated mass of 2.5 x 10^7 the mass of our Sun.
The galaxy has two tightly wound inner spiral arms within a disk with high surface brightness and two outer, more open spiral arms that originate near the inner ring. The outer arms have a few small H11 areas." - Kurt Thrust -acting CEO and current Director of the Jodrell Plank Observatory.

"Also known as Caldwell 7, NGC2403 is an outlying member of the Messier 81 Group of Galaxies. It is approximately 50,000 light years across and is some 8million lightyears distant in the dim constellation Camelopardalis. NGC2403 contains numerous star forming regions. According to our neighbour Mr Shrodinger, NGC2403 is visible in 10x50 binoculars but I have been unable to spot it in 11x80 binoculars from the Jodrell Plank Observatory. This galaxy is strikingly similar to Messier 33 in the constellation Triangulum". - Kurt Thrust acting CEO and current Director of the Jodrell Plank Observatory

NGC 2207 and IC2163 Interacting Galaxies in Canis Major

" The two barred galaxies in this image are in the early stages of colliding and merging. Both galaxies are recognizably separate . NGC2207 is in the process of tidally stripping IC2163 and in about one billion years from now they are expected to merge and form an elliptical galaxy or possibly a disk galaxy. Both galaxies contain massive amounts of gas and dust and as a result of the gravitational impact upon each other there is evidence of rapid star formation. Four Supernovae have been observed in NGC 2207 since 1975.  The collision of these two galaxies is of particular interest as it is thought to reflect the probable fate and merger between the Milky Way and the Andromeda Galaxy." - Archie Mendes - visiting theoretical astronomer at the Jodrell Plank Observatory - Reydon University - 'School of Computer Modelling and Difficult Sums'
