In January 1995, fourteen wolves were brought from Canada in wooden crates and released into Yellowstone National Park to replace the population killed off by 1926, and the question of whether they have changed the course of the park's rivers, as popular science videos viewed by tens of millions claim, has now become one of the most contested debates in ecology.

The first eight wolves arrived through the Roosevelt Arch on the morning of 12 January 1995, in a horse trailer escorted by two park service patrol cars.

W2246f sits 1.2 billion light years away with an old, quiet central kiloparsec and a still-star-forming disk, but MUSE found no recent collision or active nucleus to explain the galaxy’s split personality

W2246f looks calm in exactly the place astronomers expected trouble. The spiral galaxy sits about 1.2 billion light years from Earth, spans…

Mind & Meaning

We tend to imagine later life feeling bleaker, but researchers tracking emotions for over two decades found the opposite pattern — negative feelings tended to fade with age while positive ones held largely steady, hinting at quiet contentment.

For a while in my late twenties and early thirties I half-believed the years ahead would mostly get heavier, with body and mood quietly sliding together and I am not alone in that forecast.

Constellations

In August 1971, the Apollo 15 astronauts left a small aluminum figurine and a plaque on the Moon called the Fallen Astronaut, listing fourteen Americans and Soviets who had died in the race to get there, and they said nothing about it over the radio, revealing it only after they were safely back on Earth.

On 2 August 1971, in the dust of the Hadley-Apennine landing site, Apollo 15 commander David Scott crouched beside the Lunar Roving Vehicle…

Mind & Meaning

When researchers analyzed how 35,000 Americans spent their days, more free time tracked with greater happiness but only up to a point, after which extra empty hours appeared to make people feel worse, not better

Ask almost anyone what they want more of and the answer comes back fast: time. Time off, time away, time without the calendar dictating the shape of the day.

Space Scopes

Five astronauts just spent hours hiding inside a Dragon capsule while the ISS leaked — and the real story isn't the hole, it's the argument NASA had with Roscosmos over a saw

At 9:04 a.m. Eastern time on Friday, June 5, mission control in Houston told five astronauts on the International Space Station to put on…

What’s up in

Mind & Meaning

The psychology of ambition, isolation, and meaning under extremes — and what frontier life teaches us about being human.

Constellations

Sunsets on Mars glow blue rather than red, because the fine dust suspended in its thin air scatters sunlight so that the blue gathers into a halo around the setting sun while the rest of the sky stays yellow and orange, leaving the planet that looks rusty all day to end it with a cool blue glow.

Constellations

The Andromeda galaxy is the most distant thing you can see with the naked eye, and the light reaching your eyes from it tonight left some 2.5 million years ago, long before our own species existed.

Science

Glass frogs can turn much of their body see-through while they sleep by pulling almost all of their red blood cells out of circulation and storing them in their liver, then releasing them again when they wake and need to move.

Science

The human body gives off a faint glow of visible light, produced by ordinary chemical reactions inside living cells. It is real light, but it is far too weak to see: roughly a thousand times below the sensitivity of the naked eye, so to us the body appears completely dark.

What’s up in

Science

Physics, climate, planetary science, and the research that shapes how we understand the universe.

Climate Science

The town of Mawsynram in northeastern India receives roughly 11,872 millimetres of rain a year, so much that residents weave body-length shields called knups from bamboo and banana leaf to walk hands-free through downpours that can last weeks without pause.

Science

The smell that fills the air during the first rainfall after a dry spell is called petrichor, and it comes from plant oils, soil bacteria, and a molecule the human nose can detect at almost unbelievable concentrations

Science

The Pando aspen grove in Utah looks like 47,000 separate trees, but every trunk is a genetically identical clone connected by a single underground root system weighing roughly 6,000 tons, making it possibly the heaviest living organism on Earth and at least 14,000 years old.

Mind & Meaning

The DNA in a single human cell, if stretched into a single thin line, would extend approximately 2 meters — and the total DNA in your entire body, if connected end to end, would stretch from Earth to the Sun and back roughly 245 times, all packed into cells so small that tens of thousands of them would fit on the head of a pin

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.
