The human brain accounts for about two per cent of body weight and consumes about twenty per cent of the body's total energy every day — and that consumption barely changes whether you are solving differential equations or staring at a wall

The number that gets repeated in pop-science columns is the 2/20 split (that the brain is 2% of body weight but consumes 20% of energy) — a small organ, enormous appetite — and I think it's fair to suggest that many people are led to…

A common dietary supplement — omega-3, the kind found in fish oil and flax — has been shown across nearly 4,000 people to reduce aggression by up to 28%, whether it's the heat-of-the-moment kind or the kind people plan in advance

The standard cultural framing of how aggression operates has, for most of the contemporary period, been calibrated to a particular set of explanatory variables.

The Arecibo message — humanity’s most famous deliberate radio message to another civilization — was aimed at a star cluster about 25,000 light-years away in 1974, meaning even an immediate reply would not reach Earth until around 52,000 CE

Imagine standing under a tent on a karst hillside in Puerto Rico, on an afternoon in November 1974, watching the dedication of a remodeled radio telescope.For just under three minutes it warbles at the sky.

In 1991, eight people sealed themselves inside a glass world in the Arizona desert for two years, and the experiment nearly unravelled when the oxygen began disappearing from the air they were breathing

On 26 September 1991, eight people were sealed inside Biosphere 2, a three-acre enclosure of glass and steel near Oracle, Arizona.

The tallest known living thing on Earth is a coastal redwood named Hyperion that stands 380 feet tall in a hidden grove in California, and its exact location is kept secret by the National Park Service because the last time tourists found a record-holding redwood they trampled its root system so badly the tree began dying.

Hyperion stands roughly 380 feet tall in a fold of coastal forest in Northern California, a single coast redwood widely recognized as the tallest living thing on Earth.

Voyager 1’s famous Pale Blue Dot photograph was nearly never taken — Carl Sagan pushed NASA to turn the camera back toward Earth after the planetary mission was over, while engineers worried the Sun’s glare could damage the optics

On February 14, 1990, six billion kilometers from the sun, Voyager 1 swiveled around and took a photograph of Earth.

Mind & Meaning

In 1518 in Strasbourg, a woman stepped into the street and began to dance, and within a month roughly 400 people were dancing alongside her — some of them, according to later accounts, until they collapsed and died — and no one has ever fully explained why

Earth News

In 1908 something exploded over a remote part of Siberia with the force of roughly 1,000 Hiroshima bombs, flattened 80 million trees, and was heard 600 miles away — and more than a century later, scientists still cannot fully agree on whether it was an asteroid, a comet, or something else entirely

A meteorite that fell near the Australian town of Murchison in 1969 was found to contain grains of stardust up to around 7 billion years old — the oldest solid material ever identified on Earth, formed long before the Sun or planets existed.

Every GPS satellite is launched with a clock deliberately set to run slow, because Einstein's relativity speeds it up by about 38 microseconds a day once in orbit — and without that built-in correction, your phone's location would drift by roughly ten kilometres a day.

About Space Daily

Space, science, and the human side of the frontier. Since 1995.

Space Daily is an independent publication covering three connected beats: the space industry, the science behind it, and the psychology of ambition, isolation, and meaning under extremes. Founded in Tokyo in 1995, we’ve built a thirty-year archive of rigorous reporting on the people, missions, and ideas pushing humanity outward — and on the human dynamics shaped by frontier life. The same ambitions, pressures, and patterns of mind that drive humanity to the stars also shape how we live on Earth. We employ modern AI technologies to support our editorial workflows; every published piece is editorially directed and reviewed.
