These magnificent beasties are the armoured vehicles of the insect population and the largest terrestrial-dwelling beetles in the UK. Their common name is a reference – unsurprisingly – to their antler-shaped “mandibles” or jaws, which they use to fight over territory, but not, perhaps surprisingly, to win the respect of female Stag Beetles..!
These Curious Creatures have intrigued me ever since I found an expired female stag beetle (see below ) in a south-west France many years ago. I drew it next to a blackbird’s feather, captivated by the different tones of black, the textural contrasts and inky depths of colour. I found it – and still find them all as a species – fascinating and beautiful, particularly the males, with their extraordinary maroon-red mandibles.
This week saw an exciting announcement from the US space agency, NASA with the safe arrival of its MAVEN spacecraft in orbit around Mars. But how did it get there and what is its mission?
Once a year, in August, Stourton Stables had a summer camp. Fifteen lucky kids were invited to spend a whole week with their pony, grooming, tacking up, and riding every day. There would be a jumping competition and picnic hacks, a visit to the three counties showground, and a swim at the leisure centre.
I was allocated Heidi, a grey mare with a snotty attitude. Literally. One of her tricks was to toss her head about whilst being ridden and flick massive globs of snot and foam backwards into the rider’s face.
Aside from the snot, she was zippy and responsive, pleasant enough to ride; but her main problem was she was evil to groom and tack up. She was a biter and a kicker. Hence I gave an audible groan when they announced we would have to wash our pony’s tail. Drat!
Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.
When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.
Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.
The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.
The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:
“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”
Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.
