Winter Wonderings – Are Snowflakes Really All Different?

It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.

However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.

The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!

Woolly Hugs

Sometimes sad things happen, and when that happens we need a hug.

Sometimes sad things happen to people we know, and we offer them a hug.

Sometimes sad things happen to people we don’t really know and we feel helpless. We want to offer comfort but don’t know how. We want to hug them, but they are too far away, or not really good enough friends so that we feel we can offer a hug.

Stories from the Stables – Part 4 – Summer Camp

Summer Camp at the Stables, from Carolyn Ward

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!

Interview with Skeleton Athlete Jor’dan McIntosh

Jor’dan McIntosh is one very special athlete. Currently studying at Loughborough University, the Derby born 23 year old is specialising in one of the most gruelling yet exciting Winter Olympic events. Because right now, while her compatriots compete in Sochi for Skeleton Gold, Jor’dan is perfecting her technique, in her aim to be the best female Skeleton athlete come the next Winter Games in PyeogChang South Korea 2018.

What is Juno?

There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?

What is Juno?

Juno is a spacecraft designed and operated by NASA, the US space agency. It was launched from Cape Canaveral on the 5th August 2011 and has taken almost 5 years to travel the 716 million kilometres to Jupiter, the largest planet in our solar system. Juno is 3.5 metres in height, and when its solar arrays are extended it’s more than 20 metres across. These arrays are covered in more than 18,500 solar cells, which allows Juno to operate even when it’s at such a great distance from the Sun.

Why is it called Juno?

In Roman mythology Juno was the Queen of the gods. She was married to the king, Jupiter, who wasn’t always well-behaved. Juno had to peer through the clouds to discover what he was up to; the spacecraft is called Juno because it will be looking beneath the clouds that cover the surface of the planet Jupiter.

Aboard the Juno craft are 3 models of Lego minifigures: Jupiter, Juno and Galileo, who discovered in 1610 that Jupiter had moons.

What is it looking for?

Jupiter is enormous; it’s two and a half times larger than all the other planets in our solar system combined. It’s made entirely of gases and is believed to have no solid surface. The planet rotates at an immense speed, completing one rotation every ten hours, and telescopes have shown us that it has a cloudy atmosphere with colourful spots and stripes. The largest of these, known as the Great Red Spot, is a storm that is several times the size of Earth and has been raging for more than 300 years.

This mission is the first time that humans will be able to glimpse what lies beneath Jupiter’s cloudy atmosphere. The main objective is to understand how the planet formed and evolved, which will give us more information about the formation of gas giants as well as the rest of the solar system. Juno will also measure the quantities of water and ammonia within the atmosphere, examine the magnetic field that surrounds the planet, observe any polar auroras and measure the gravity to see whether a solid core may exist after all.
