Cancer, also known as "the dark sign", is a medium sized constellation surrounded by Gemini to the West, Leo, Canis Minor and Hydra. The Brightest star in Cancer is Beta Cancri which only has an apparent magnitude of 3.5. So it's brightest star isn't overly bright and neither are the rest of them hence the … Continue reading The Constellation Cancer
I admit, last weeks post was slightly shorter than most other posts I’ve ever written. Following on from this I have decided to complete a series on the signs of the zodiac from the point of view of astronomy. The Zodiac are the star groups and systems can observe from Earth depending on the time … Continue reading Signs Of The Zodiac Series

Will the Universe expand forever? A frequently asked question in the comments on the website. I touched on this in the past during the cosmology and dark energy topics covered in previous posts but it certainly deserves a post in its own right. Cosmology deals largely with the universe as a whole considering all the … Continue reading Will The Universe Expand Forever?
At the instant of the Big Bang, the universe began its inflation. Expanding outwards in all directions faster than the speed of light before cooling and forming all the bodies we can observe now. For decades it was assumed that the velocity and distribution of galaxy clusters should be pretty even across the universe with … Continue reading Dark Flow

If the Earth stood still suddenly, everything not attached to the crust of the Earth would just be swept up into the … Continue reading The Day The Earth Stands Still
In the mathematics of Einstein's Theory of Relativity, black holes are predicted and astronomers have proven beyond all doubt that they exist. The centre of our own galaxy harbours one of these monstrosities and so do nearly all galaxies observed. In the same mathematical models which predict black holes, there are predictions for entities which … Continue reading White Holes
