The night sky is literally full of stars, planets, galaxies, comets, asteroids, gas clouds, subatomic particles, photons, neutrons, moons and supernova remnants scattered in every direction. Despite the amount of visible matter that our own eyes and telescopes can pick up, this is only around 5% of the total matter in space. So where is … Continue reading The Gravity of Some Dark Matters…
In the modern world, everything we know is built on a foundation of numbers and their relationships. It's hard to imagine a time when that was a radical idea, but such a time existed. In fact, 2500 years ago, the Pythagoreans (named after their founder) were a mystic cult based on this very premise. It's difficult … Continue reading The Shape of Things to Come – Geometry as a Path Through the Universe (and Other Puns)
The term cardiovascular means heart (cardio) and blood vessels (vascular). They work together in a synergistic and complimentary fashion to ensure adequate oxygenated blood supply to the entire body. There are many different factors that can influence how that happens, gravity being one. In fact, if you think about it, its’ the very reason why … Continue reading Cardiovascular system in space!
I actually hoped to write about the search for life in a later blog post but the powers that be at NASA have been in the media recently speculating the chances of life on Enceladus, the sixth largest moon of Saturn. Enceladus is a frozen world orbiting Saturn with a surface of fresh clean ice. … Continue reading Enceladus, Titan and the Search for Life
Genetics are what makes you, you. They dictate everything from your eye colour to whether you’re a human or a T-Rex (imagine having tiny arms and a massive head like that when you’re trying to take a selfie). Genetics are also a group name for our genome which is like a biological computer code that … Continue reading Genes for Jeans?
Recently, on one of the surveying trips I was participating in for the charity ORCA (who specialise in conservation of marine mammals in UK and international waters), I was talking to the Captain of the ship and he told me about a species of Jellyfish he had recently read about called Turritopsis dohrnii. Like all … Continue reading A Tale of the Immortal Jellyfish
In this article I would like to discuss our place within the Solar System, and the origin of this magnificent structure as well. The Solar System is a gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets … Continue reading Our Place in the Stars
Last month I discussed that one of the most popular methods of exoplanet detection was the transit method. This is the process of looking at the “brightness” of the star, and seeing how it varies when the planet passes over the face of the host star, as seen from Earth. The transit method is the … Continue reading Photometry in Exoplanet Detection
In the last post we discussed how the stars came to be following the Big Bang. Stars are not all similiar and like every good thing in life, there is variety and diversity in the fabric of space that our stars are embedded in. Lads and lasses take note, when you are having a romantic … Continue reading I’m What Lies Between the Stars?
