Supercooled phase transitions: Could they explain gravitational wave signals?

A new study published in Physical Review Letters explores the possibility that a strongly supercooled, first-order phase transition in the early universe could explain gravitational wave signals observed by pulsar timing arrays (PTAs).

High winds delay SpaceX launch after a switch to Cape Canaveral

A late scrub due to weather on June 18 means it will have been at least 12 days since SpaceX last lit up the Space Coast sky with a rocket launch, the longest run between launches in more than a year.

The design of a photonic alloy with topological properties

Photonic alloys, alloy-like materials combining two or more photonic crystals, are promising candidates for the development of structures that control the propagation of electromagnetic waves, also known as waveguides. Despite their potential, these materials typically reflect light back in the direction where it originated.

Tropical solstice shadows

Solstices mark the changing of seasons, occur twice a year, and feature the year’s shortest and longest daylight hours—depending on your hemisphere. These extremes in the length of day and night make solstice days more noticeable to many observers than the subtle equality of day and night experienced during equinoxes.

Laying the foundation for lunar base construction: Elucidating lunar soil-microwave interactions

NASA aims to construct a lunar base through the Artemis program, a manned lunar exploration initiative. However, the practical reality of what the general public envisions for the space base differs somewhat from well-known science fiction movies. To build a base on the moon using abundant and diverse construction materials, significant transportation costs are involved. […]

New theory broadens phase transition exploration

In a paper recently published in Physical Review Letters, Los Alamos National Laboratory researchers offer a new theory that predicts defect density across a variety of phase transitions. The research opens new routes for the exploration of defect formation in fields such as materials science, high-energy physics and cosmology.
