Psychologist Laura Carstensen uncovered a surprising upside to growing older: as our sense of the time we have left grows shorter, we invest more in the people and activities that matter most to us

This piece summarises published research on ageing and emotional well-being. We are not psychologists or clinicians, and nothing here is psychological advice.

The electric eel can generate a jolt of around 600 volts — several times the shock from a household socket — by stacking thousands of specialised cells together like tiny batteries, and rather than only zapping prey underwater, it has been filmed rearing up out of the water to press its chin directly against a larger attacker

The number that anchors everything is about 600 volts. That is the peak discharge an electric eel can deliver, several times the roughly 120 volts of a North American wall socket.

Psychology

Quote by Hannah Arendt: “Loneliness is not solitude. Solitude requires being alone whereas loneliness shows itself most sharply in company with others.”e: "He who has a why to live for can bear almost any how."

Thought of the week, from Hannah Arendt: "Loneliness is not solitude. Solitude requires being alone whereas loneliness shows itself most sharply in company with others.

The Australian superb lyrebird can imitate almost any sound it has ever heard — chainsaws, camera shutters, car alarms, the calls of more than 20 other species — with enough accuracy that the birds being imitated often can't tell the difference

When researchers at the Australian National University played recordings of superb lyrebird mimicry to grey shrike-thrushes, the shrike-thrushes responded to the fakes much as they would to one of their own.

In 2021, a team at Nottingham Trent University led by Nadja Heym surveyed almost 1,000 people and found that the dangerous personalities don't lack empathy — they just use the cognitive half without the affective one

In 2021, a team at Nottingham Trent University surveyed almost 1,000 people in the UK and found something that broke the standard textbook on dangerous personalities.

Deep Space

A rogue planet five to ten times the mass of Jupiter, drifting alone through space without a parent star, was observed by European astronomers in 2025 devouring six billion tons of gas and dust every second — eight times faster than just months earlier — in the most powerful accretion event ever recorded for any planetary body, happening 620 light-years from Earth as you read this

Somewhere in the Chamaeleon constellation, six hundred and twenty years ago, a small dark planet about the size of Jupiter began to do something planets are not supposed to be able to do.

Mind & Meaning

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

The James Webb Space Telescope may have seen the chemical fingerprint of a molecule linked to marine life on Earth in the atmosphere of K2-18b, 124 light-years away. But the signal is still tentative: it could be dimethyl sulfide, a related sulfur compound, or something else entirely, and scientists have not yet ruled out non-biological explanations.

Mars can produce dust storms so vast they swallow the planet. In 2018, one of them turned day into darkness for NASA’s solar-powered Opportunity rover, cutting off the sunlight that had sustained it through more than 14 years on Mars.

Cosmology

On a September night in 1999, a 25-year-old graduate student stepped into a modest wooden shed in a Colorado parking lot and used a tiny four-inch telescope to spot a 1% dip in a star's light—a backyard experiment that proved alien planets could be tracked by their shadows and opened the floodgates to discovering thousands of worlds

Apollo astronauts trying to sleep on the way to the Moon kept seeing flashes and streaks in the dark, and the cause turned out to be cosmic rays from deep space passing straight through their eyes.

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.
