People who imagine their self to reside in their head or their heart have different approaches to life. Columnist David Robson explores the benefits of learning to shift where you sense your self, and how this practice could improve your relationships and decision-making

The Moon, Venus, and Jupiter — the three brightest celestial objects after the Sun — will form up beautifully in twilight this Monday, Tuesday, and Wednesday.

Dark matter makes up roughly 85 percent of all the matter in the universe. We have never directly detected a single particle of it. But a new method developed by physicists at MIT and across Europe may have just opened a door we didn't know existed. When two black holes collide and merge, they send ripples through the fabric of spacetime, these are known as gravitational waves and if those black holes happened to spiral through a dense cloud of dark matter on their way in, those waves carry an imprint of it. For the first time, scientists have a technique to read that imprint and one signal in the existing data is already raising eyebrows.

Artemis II has barely left the headlines. On April 1st 2026, four astronauts climbed aboard NASA's Orion spacecraft, rode the most powerful rocket ever to carry humans beyond low Earth orbit, and swung around the far side of the Moon. The world watched. Now, before the dust has settled, NASA has outlined its plans for what comes next. Artemis III won't be landing on the Moon. But what it will do is arguably just as important and if history is any guide, it's exactly the kind of mission that makes the difference between a Moon landing and a disaster.

Right now, as you read this, Earth is drifting through a cloud of debris from an ancient stellar explosion. Stardust, real stardust, is raining down on us so thinly scattered that we have only just found the proof. Locked inside Antarctic ice cores up to 80,000 years old, an international team led by the Helmholtz-Zentrum Dresden-Rossendorf has discovered traces of iron-60, a radioactive isotope that can only be created in the heart of an exploding star.

A planetary odd couple — a mini-Neptune and a hot Jupiter — probably formed much farther away from their star before migrating closer in.

The nation’s top court extended a stay on a lower court order banning telemedicine access to mifepristone, a drug used in medication abortions—but the order sets up a longer legal fight

For ten years, astronomers at UCLA have been pointing one of the world's most powerful radio telescopes at the stars and listening. Not for pulsars or gas clouds, or the hiss of the cosmic microwave background, but for something far more extraordinary. A signal from another civilisation. The result of a decade's work, 70,000 stars, and 100 million candidate signals is now in and every single one of them was us! But far from being a disappointment, the findings are among the most rigorous and revealing in the history of the search for extraterrestrial intelligence.

The El Niño climate event is due to return this year, with U.S. forecasters predicting an 82 percent chance of it coming in May through July and a 96 percent chance for it doing so in December through February 2027

Shalbatana Vallis is a 1300 km water channel on Mars. It was carved out in one cataclysmic flooding event, possibly triggered by a massive impact. It's more evidence that liquid water once flowed on Mars.

In a “breakthrough,” researchers demonstrate how engineered bacteria held in a jellylike container could help fight infection in mice

University of Cincinnati astrophysicist Paul Smith is part of an international team studying TOI-2031Ab, a gas giant orbiting a star 901 light years from Earth. Smith and his colleagues used the James Webb Space Telescope to study its atmosphere.

The hantavirus cruise outbreak may not have started in a garbage dump in Ushuaia, Argentina, after all

One of the core community surveys of NASA’s Nancy Grace Roman Space Telescope, the Galactic Bulge Time-Domain Survey, is expected to locate over a thousand exoplanets that orbit far away from their stars, beyond the orbital distance of Earth from the Sun. Although Roman hasn’t launched yet, astronomers already are gathering useful supporting data by utilizing NASA's Hubble Space Telescope, which could assist astronomers in analyzing Roman data.

The Psyche spacecraft is bound for a metal-rich asteroid that it will examine up close starting in 2029. But first, it needs to swing past the Red Planet

The rare isotope helium-3 is one of Earth’s most precious commodities—so precious, in fact, that it might prove profitable to mine from the moon
