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). Go to Source A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors. Go to Source “So hot, oh my God,” one officer can be heard saying in the video. “They’re so hot. She was trying to sell the puppies. They were all tied up in the bag. They’re dripping in sweat” Go to Source NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Lockheed Martin Corp. of Littleton, Colorado, to build the spacecraft for NOAA’s Geostationary Extended Observations (GeoXO) satellite program. Go to Source 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. Go to Source Astronomers from India and Thailand have observed a young nearby open cluster known as Berkeley 59. Results of the observational campaign, published June 12 on the pre-print server arXiv, deliver essential information regarding low-mass stellar and substellar content of this cluster. Go to Source When a White Settlement officer arrived, the woman was on the phone with the scammers; BWC video shows the officer taking over the phone call, putting an end to the scam Go to Source 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. Go to Source The motive for the proposed new citation is to help Seattle police crackdown on large street racing events, giving police tools to “hold vehicle owners accountable” Go to Source It’s been 11 days since SpaceX last lit up the Space Coast sky with a rocket launch, the longest run between launches in more than a year. Go to Source After months of driving, Perseverance has finally arrived at “Bright Angel,” discovering oddly textured rock unlike any the rover has seen before. The team now plans to drive up the slope to uncover the origin of this rock sequence and its relationship to the margin unit. Go to Source NASA and Boeing are targeting a June 26 return to Earth of the Boeing Starliner from the International Space Station, officials said Tuesday. Go to Source 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. Go to Source […] 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. […] 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. Go to Source […] |
