Hi, I'm Rob, and I’m a keen astronomer. I found astronomy while working in dark rural locations. Initially, I explored the night sky and learnt the constellations before purchasing a pair of binoculars to further my knowledge of the sky. My first telescope was a 200 mm Newtonian reflector on an equatorial mount. I found that this telescope had a steep learning curve but was a rewarding experience. As time progressed, I became interested in astrophotography. This resulted in purchasing a 110 mm refracting telescope and a dedicated monochrome-cooled astronomical camera. This resulted in another very rewarding steep learning curve that far surpassed the experience with my first telescope. I have joined Telescope Guru to share my knowledge of telescopes and astronomy.

Dark Matter: The Hidden Mass Shaping the Universe

Galaxy cluster with dark matter and arcs

For many years, it was thought that all the mass of the universe was present in a form that we can detect due to its emission of electromagnetic radiation. Since the 1930s, evidence has mounted that this assumption was incorrect. This change of thought was based on the observations that galaxies in clusters had orbits […]
