Stars twinkle because of the way light is disrupted as it passes through Earth’s atmosphere

Starlight is affected by the winds in our atmosphere as it enters, as well as being affected by different areas and temperatures.

This causes the light from each star to twinkle as we look at them.

Most Sun-like stars in our galaxy are in multiple star systems

Our Sun may be a single star, but it is in the minority.

Over half of the Sun-like stars in the Milky Way are part of multiple star systems, binaries or triplets, with stars orbiting around a common centre of mass.

Most lower-mass stars like red dwarfs, however, live alone without a companion.


The closest galaxy to us is the Andromeda Galaxy – it’s estimated at 2.5 million light-years away

Before the discovery of the Andromeda Galaxy, the Large Magellanic Cloud was believed to be the closest galaxy to us.


This Monster Black Hole Is The Most Powerful In The Universe! This supermassive black hole known as Cygnus X-1 is the heaviest stellar black hole ever observed. Being about 21 times the mass of our sun, this black hole produces the strongest energy waves ever discovered. Cygnus X-1 lies approximately 6000 light years away, and is about 5 million years old


There are more stars in space than there are grains of sand in the world

There are 10 times more stars in the night sky than grains of sand on the Earth, with 70 sextillion stars being visible from Earth through a telescope.

To put that in numbers, 70 sextillion is this: 70,000,000,000,000,000,000,000.


At any given moment, there are at least 2,000 thunderstorms happening on Earth

Worldwide, there are an estimated 16 million thunderstorms each year.

Roughly 100,000 of these thunderstorms happen in the U.S. alone.


Halley’s Comet will pass over Earth again on July 26, 2061

This space fact is one for kids to look forward to!

The famous comet was last seen on February 9, 1986, and only orbits the Earth once every 75 – 76 years.


The Black Arrow is the only British satellite to be launched using a British rocket

Black Arrow was developed during the 1960’s and was used for four launches between 1969 and 1971.

In 2019 it was retrieved from its crash landing site in the Australian outback and put on a display Penicuik, Scotland.


The Sun loses a billion kilos per second

Particles in the Sun’s upper atmosphere are so hot and energetic that they speed out into space as part of the solar wind.

Our star sheds around 1.3 trillion trillion trillion particles every second. This equates to roughly one billion kilograms of matter per second, or one Earth every 185 million years.


The Whirlpool Galaxy (M51) was the first celestial object identified as being spiral

The grand, spiraling arms of the Whirlpool Galaxy are made up of long lanes of stars and gas, sprinkled with lots of space dust.

These arms act as star formation factories, compressing hydrogen gas and creating clusters of new stars.


Comets and asteroids are leftovers

No, we don’t mean leftovers to eat — we mean leftovers of what the Solar System used to look like. So while it’s easy to get distracted by the weather and craters and prospects for life on planets and moons, it’s important to remember that we must also pay attention to the smaller bodies. Comets and asteroids, for example, could have brought organics and water ice to our own planet — providing what we need for life.


The Mariner 10 was the first spacecraft that visited Mercury in 1974

It was launched at NASA’s Kennedy Space Center in 1973 and flew by Venus 3 months later. It then crossed into Mercury’s orbit managing to photograph 45% of Mercury’s surface.

The second spacecraft to visit Mercury was the “Messenger”, which completed mapping of 100% of Mercury’s surface in 2013.




In 3.75 billion years the Milky Way and Andromeda galaxies will collide

The Andromeda Galaxy is approaching the Milky Way – where our solar system is – at rate of around 110 kilometres per second (68 mi/s) and eventually the two will collide to form a giant elliptical galaxy.


There is floating water in space

Astronomers have found a massive water vapor cloud which holds 140 trillion times the mass of water in the Earth’s oceans somewhere around 10 billion light years away – making it the largest discovery of water ever found.


The first-ever black hole photographed is 3 million times the size of Earth

The photo was released in April 2019 and shows a halo of dust and gas 310 million trillion miles from Earth.

It was captured by the Event Horizon Telescope, a network of eight linked telescopes, and was also captured due to the algorithm of programmer Katie Bouman.


No one knows how old Saturn’s rings are

There’s a field of ice and rock debris circling Saturn that from afar, appear as rings. Early telescope observations of the planet in the 1600s caused some confusion: does that planet have ears, or moons, or what? With better resolution, however, it soon became clear that there was a chain of small bodies encircling the gas giant. It’s possible that a single moon tore apart under Saturn’s strong gravity and produced the rings. Or, maybe they’ve been around (pun intended) for the last few billion years, unable to coalesce into a larger body but resistant enough to gravity not to break up.


Buzz Aldrin’s birth name was Edwin Eugene Aldrin Jr

He got the nickname “Buzz” from his sister’s mispronunciation of the word “brother”, which became “buzzer”.

In 1988, he legally changed his first name to “Buzz”.
