There are more trees on Earth than stars in the Milky Way. A major global estimate put the planet’s tree count at about three trillion, while NASA gives the Milky Way’s star count as roughly 100 to 400 billion.
Seven miles beneath the Pacific Ocean, in the deepest place on Earth, American explorer Victor Vescovo descended in 2019 to a depth where the pressure equals 50 jumbo jets stacked overhead — and at the bottom of the Mariana Trench, where no light has ever reached, he found a plastic bag and several candy wrappers waiting on the seabed.
On a sunny day, the top of the Eiffel Tower slowly drifts in a small circle about six inches wide — it isn’t the wind, it’s the sun, heating one side of the iron at a time and making the whole tower lean a little away from whichever side is warmest

The single loudest sound ever recorded was the eruption of the Krakatoa volcano in 1883 — heard from approximately 4,800 kilometers away in the middle of the Indian Ocean — with a sound wave so powerful it traveled around the entire planet four times, was measured on barometers thousands of miles distant, and ruptured the eardrums of sailors aboard ships up to 65 kilometers from the eruption site
A single bolt of lightning can heat the air around it to roughly five times the temperature of the surface of the Sun, and it is the violent expansion of that superheated air that creates the crack of thunder.
Nearly four kilometres beneath the Antarctic ice sheet lies Lake Vostok, a hidden lake the size of a small sea. It has been cut off from sunlight and the atmosphere for hundreds of thousands, and perhaps millions, of years — making it one of Earth’s closest rehearsals for the buried oceans of Europa and Enceladus, where any life would also have to survive in darkness beneath a frozen shell.
The ocean produces roughly half of Earth’s oxygen — not the rainforest, which uses up most of what it makes — through photosynthesis by phytoplankton, microscopic marine organisms so abundant that a single teaspoon of seawater can contain as many as a million of them.

Chemists have demonstrated for the first time how RNA may have copied itself on early Earth — solving a bottleneck that had blocked the origin-of-life field for decades
A single kilogram of conventionally farmed beef requires approximately 15,400 litres of water to produce, the equivalent of around 100 standard bathtubs, and generates approximately 99 kilograms of carbon dioxide equivalent in greenhouse gas emissions, the equivalent of driving an average car about 250 miles.
There is more freshwater locked inside the rocks of Earth’s mantle than in every river, lake, and surface reservoir on the planet combined, hidden in a mineral called ringwoodite hundreds of miles beneath your feet
In 1868 astronomers found a new element in the Sun’s light, named it helium for the Greek word for the Sun, and no one found a trace of it on Earth for another 27 years
In September 2023 a mega-tsunami in Greenland sent tremors around the entire planet for nine days and scientists have only just confirmed how
A team led by Nick Mortimer at GNS Science in New Zealand spent two decades mapping the basalt and granite floor of the Tasman region before formally naming Zealandia in a 2017 paper, ending more than a century of arguments about whether a submerged landmass could still count as a continent.
