Quantum semiconductor design could expand search for dark matter

Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical particles that many physicists think could make up dark matter.

Analog gravity advance offers new insights into Hawking radiation from black holes

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint radiation themselves. This radiation has not yet been observed in space; instead, researchers use models in the laboratory that mimic […]

LSST begins full operations with key contributions from Japanese researchers and engineers

NSF–DOE Vera C. Rubin Observatory has officially begun full operations for the Legacy Survey of Space and Time (LSST), one of the world’s largest astronomical imaging surveys. Behind the scenes, Japanese researchers and engineers are drawing on technologies and expertise cultivated through the development and operation of the Subaru Telescope to support the project’s software, […]

New star activity catalog could sharpen hunt for habitable worlds

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star’s habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the planet’s surface, life is abundant. But what about the exoplanet’s […]

Cosmic dust could play key role in cracking long-standing mystery of solar corona heating

A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar corona, the outer atmosphere of the sun. The discovery potentially […]

Nautilus array to track missing exoplanet atmospheres

Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can’t be directly imaged yet, so astronomers must get creative in how they search for signs of life, also called biosignatures. Presently, powerful ground- and space-based telescopes like the Atacama Large Millimeter Array (ALMA) and […]

TESS just found a planet in a new way—and more may be hiding in its eight years of data

For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing world is a super-Jupiter orbiting far from its host star.
