The coldest capital city in the world is not in Russia, Scandinavia, or Canada — it's Ulaanbaatar, Mongolia, which has an annual average temperature of -1.3°C (29.7°F), the only national capital with a sub-zero annual average, and where January nighttime temperatures regularly drop to -35°C (-31°F), making it colder than Moscow, Reykjavík, Astana, and Ottawa combined
Science
Jupiter’s Great Red Spot is a storm wider than Earth that has raged for at least 150 years. Once large enough to swallow several Earths, it has been shrinking for more than a century, and astronomers can now track its changing size decade by decade.

The largest known volcano in the solar system is on Mars — Olympus Mons, a mountain so vast that its base would cover the entire state of Arizona, with a peak rising nearly 22 kilometers above the surrounding plain, almost three times the height of Mount Everest — and it is gentle enough in slope that an astronaut walking up its flank might not realize they were climbing a mountain at all

The first computer virus to spread across the global internet was released by accident in November 1988 by a 23-year-old Cornell graduate student named Robert Morris — who claimed he only wanted to measure the size of the internet, but a coding error caused his program to replicate uncontrollably, crashing roughly 10 percent of all computers connected to the network at the time and resulting in the first criminal conviction in history for cyber-misconduct
Psychology
In 1972, New Zealand researchers began following more than a thousand babies born in a single coastal city, intending to study how childhood shapes adult life — and more than five decades later, the single childhood trait that most consistently predicts adult health, wealth, and happiness is not intelligence or family income, but something much harder to teach
Science
Time really does run faster for your head than for your feet. According to general relativity, clocks higher in Earth’s gravitational field tick slightly faster — and physicists have now measured the effect across distances as small as a millimetre.

Mercury is not the hottest planet in the solar system despite sitting closest to the Sun, because Venus traps so much heat under its thick atmosphere that it stays hotter day and night.

Carl Sagan and four colleagues published the 1983 'TTAPS' paper that introduced the phrase 'nuclear winter', and the calculations that frightened Reagan and Gorbachev into arms talks were first run not on a supercomputer but on a model originally built to study dust storms on Mars.

Concept of the day: the Zeigarnik effect — how unfinished tasks nag at the mind more than finished ones
Mind & Meaning
The Mediterranean Sea was once completely dry — about 5.6 million years ago, the connection to the Atlantic Ocean was closed by geological shifts, and the entire sea evaporated into a massive salt-floored basin two miles below sea level, which remained empty for roughly 600,000 years before the Strait of Gibraltar reopened and the Atlantic refilled it in what may have been the largest waterfall in Earth's history
Science
The icy surface of Europa is constantly crystallising and reforming in different places at different rates and the James Webb Space Telescope has only just caught it happening
Human Behaviour
On December 3, 1992, a 22-year-old British software engineer named Neil Papworth sat at a desktop computer in his office and sent the first text message ever transmitted — two words long, reading simply "Merry Christmas" — to a Vodafone executive at an office party across town, who couldn't reply because mobile phones at the time had no way to send texts back

Thought of the day from Danish philosopher Søren Kierkegaard: "Life can only be understood backwards, but it must be lived forwards"

The "@" symbol that anchors every email address in the world was chosen in 1971 by a computer engineer named Ray Tomlinson because he wanted a character that would never appear in a person's name — looked over his keyboard, picked the only obscure punctuation mark available, and used it to separate the user from the machine they were on — and every email sent in the half-century since has used that same arbitrary choice
