Constipation is common in astronauts—blood tests provide new answers

For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in the stomach without the influence of gravity.

Mysterious Cygnus Bubble may trace back to microquasar, astronomers suggest

Astronomers have proposed a new explanation for the mysterious Cygnus Bubble, a vast cloud of ultra-high-energy gamma rays stretching thousands of light-years across the sky. While the bubble has generally been linked to the Cygnus X star-forming region, the new study argues that a microquasar more naturally explains its highest-energy emission. The results were published […]

Controlling the rotation direction of light without complex new materials

A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light that travels while rotating like a pinwheel to the left or right. Because different rotation directions can carry different information, […]

Tiny satellite will use the dark side of the moon to eavesdrop on whispers from the early universe

A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: What happened during the roughly 150 million years of the cosmic dark ages, before the universe’s first stars appeared?

New AI model detects hidden signs of solar eruptions hours before they emerge

Long before dark sunspots appear on the sun’s surface, a new active region—where powerful solar eruptions can originate—begins showing subtle signs of its formation. Now, researchers say a new artificial intelligence model can detect those early signals and forecast the emergence of solar active regions nearly nine hours in advance on average.

Theoretical framework expands directional light control beyond ordered crystal structures

A research team has developed a new theoretical framework that can suppress light scattering in certain directions while enhancing it in others, even in irregularly arranged materials. The work extends research on controlling light scattering, which has traditionally centered on ordered crystal structures, into the realm of disordered systems.

Synchronized star pairs unleash radio bursts via a Jupiter-Io-like mechanism

Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects observed comes in pairs that always include a compact dead star, called a white dwarf, locked in orbit with an M dwarf, a red star smaller than our sun.

Proposed 900-telescope array could detect an Earth-like exoplanet’s atmosphere in a single transit

What do you do when the observation you need comes around once a year? Well, preparation is key, but this is the awkward truth about finding another Earth. When a planet crosses the face of its star, a sliver of starlight passes through its atmosphere on the way to us, and the gases there absorb […]

TESS discovers a rare brown dwarf orbiting a massive, aging star

For decades, astronomers lumped brown dwarfs into a single category defined by mass alone—too big to be classified as planets but too small to become stars. However, this definition ignores the two very different mechanisms that can form them: the direct collapse of gas clouds and formation within the accretion disks of massive stars.
