February was packed with brilliant facts from space, sport, science, animals and maths. Here are ten of our favourites from the month, counted down from 10 to 1!
10. Penguins Use Special Calls
Penguins in huge colonies use unique calls so parents and chicks can find each other.
In the noisy crowd, each penguin recognises its family’s sound. That is impressive communication!

9. Some Clouds Weigh More Than a Million Tonnes
Clouds look soft and light, but they are made from billions of tiny water droplets.
When you add them all together, a large cloud can weigh over a million tonnes. They float because the air below supports them.
8. The Sun Holds More Than 99 Percent of the Solar System’s Mass
The Sun contains almost all the mass in our solar system.
The planets, moons, asteroids and comets share the tiny bit that remains. The Sun’s gravity keeps everything in orbit.

7. Some Volcanoes Build Islands Under the Sea
Underwater volcanoes can erupt beneath the ocean. When enough lava piles up, it can create brand new land.
Some islands you see on maps today were formed this way. Our planet is still building itself.
6. A Year on Venus Is Shorter Than a Day
On Venus, one full trip around the Sun takes less time than one full spin on its axis.
That means a year is shorter than a day there. Venus spins very slowly compared to Earth.
5. The Moon Is Slowly Moving Away
The Moon moves away from Earth by a few centimetres every year.
It is not noticeable in your lifetime, but over millions of years it makes a difference. Space is always changing.
4. Your Brain Uses About One Fifth of Your Energy
Your brain only weighs a small amount compared to your whole body, but it uses about 20 percent of your daily energy.
That is because it is always working. Thinking, remembering, moving, even dreaming all need power.
3. A Giraffe Has Seven Neck Bones
Even though a giraffe’s neck is very long, it has seven bones in its neck, just like you.
Each bone is much bigger than ours. Nature loves using similar designs in surprising ways.
2. The Olympic Torch Is Lit from the Sun
The Olympic flame is always lit in Greece using the Sun’s rays and a special mirror.
This connects the modern Olympic Games to the ancient games held thousands of years ago. It is a powerful symbol of history and unity.
1. The Longest Tennis Match Lasted More Than 11 Hours
The longest tennis match in history was played at Wimbledon in 2010. It lasted 11 hours and 5 minutes across three days.
The players kept going because neither could win by the usual margin. Imagine playing sport for that long. That takes serious determination.
