Wind-blown Wolf-Rayet bubbles are among the most rare, intriguing and tantalising objects to observe. And NGC 3199's gorgeous glowing cosmic bubble is even more rare, being one of only a handful of known X-ray-emitting Wolf-Rayet bubbles.
Small, faint and seemingly insignificant, the few faint stars that make up Pyxis, the mariner's compass, symbolize a truly historic instrument that changed the world and holds so much meaning and significance for many different reasons.
If ever there is a place to see the colours of the mythical Phoenix - the beautiful firebird that lived in the Arabian desert and whose plumage was the colours of fire - it is the Kalahari at sunset.
Last night I observed quasar 3C 273 which lies 2.4 billion light-years away. Recently I found a 2.4 billion year old stromatolite fossil... the first evidence of life on Earth. It is impossible to fathom the distance from us humans in both light and evolution...
Everyone has heard of Sigma Octantis, our southern pole star. But how many of us have ever heard of a star named Melville that lies even closer to the south celestial pole?
This extraordinary trio of objects are the result of a galaxy shredding encounter... a violent encounter between an elliptical galaxy and a smaller companion spiral galaxy that took place some 500 million years ago.
