An international collaboration of researchers has achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.

Astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. The findings suggest that this brown dwarf might generate aurorae similar to those seen on our own planet as well as on Jupiter and Saturn.

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.

An international research team has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.

A star's magnetic field must be considered in order to correctly determine the characteristics of exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. Researchers show that the distribution of the star's brightness over its disk depends on the star's level of magnetic activity. This, in turn, affects the signature of an exoplanet in observational data. The new model must be used in order to properly interpret the data from the latest generation of space telescopes pointed at distant worlds outside our Solar System.

When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system's fate.

Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.

The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.

The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. A research group introduces a new approach that tackles these challenges head-on using nanobolometers instead of traditional, bulky parametric amplifiers.

High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.

A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
