Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

Total Lunar Eclipse - September 7, 2025

 

Yesterday’s total lunar eclipse gave us a breathtaking spectacle, where the Earth covered the sunlightand dressed the Moon in its deep red cloak, offering us a unique moment of connection with the vast and mysterious universe around us.

M27 The Dumbbell Nebula

 


The End of a Star's Life M27 Nebula - A Cosmic Dumbbell

The M27 nebula, also known as the Dumbbell Nebula, represents one of the most spectacular and brightest planetary nebulae in the night sky.

The characteristic dumbbell shape that gives the nebula its name results from its unique structure.
It is located approximately 1,360 light-years from Earth in the constellation Vulpecula
Hidden at the center of the nebula lies a white dwarf star with a temperature of approximately 85,000 K. This extremely hot star is the remnant of a star that exhausted its nuclear fuel and expelled its outer layers, creating the dazzling spectacle we see today.

The nebula glows with a distinctive green-blue color, which is primarily due to doubly ionized oxygen.
This color, combined with the red regions created by ionized hydrogen, gives the nebula its impressive appearance. Scientists estimate that the M27 nebula formed approximately 9,800-10,000 years ago, based on measurements of its expansion velocity.

The M27 nebula remains one of the most accessible and spectacular targets for amateur astronomers, offering a window into the future of our own Sun, which in about five billion years will follow a similar evolution.
