Published The rich meteorology of Mars studied in detail from the Perseverance rover
(via sciencedaily.com) Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and daily cycles of temperature and pressure, as well as their significant variations on other time scales resulting from very different processes.
Published Can you trust your quantum simulator?
(via sciencedaily.com) Physicists have developed a protocol to verify the accuracy of quantum experiments.
Published Blast chiller for the quantum world
(via sciencedaily.com) The quantum nature of objects visible to the naked eye is currently a much-discussed research question. A team has now demonstrated a new method in the laboratory that could make the quantum properties of macroscopic objects more accessible than before. With the method, the researchers were able to increase the efficiency of an established cooling method by an order of a magnitude.
Published 17-pound meteorite discovered in Antarctica
(via sciencedaily.com) Antarctica is a tough place to work, for obvious reasons -- it's bitterly cold, remote, and wild. However, it's one of the best places in the world to hunt for meteorites. That's partly because Antarctica is a desert, and its dry climate limits the degree of weathering the meteorites experience. On top of the dry conditions, the landscape is ideal for meteorite hunting: the black space rocks stand out clearly against snowy fields.
Published New small laser device can help detect signs of life on other planets
(via sciencedaily.com) As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical -- especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University of Maryland-led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors--all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite.
Published The world in grains of interstellar dust
(via sciencedaily.com) Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles.
Published How do rocky planets really form?
(via sciencedaily.com) A new theory could explain the origin and properties of systems of rocky super-Earths and their relationship with the terrestrial planets of the solar system.
Published Martian meteorite contains large diversity of organic compounds
(via sciencedaily.com) Unraveling the origin stories of the Tissint meteorite's organic compounds can help scientists understand whether the Red Planet ever hosted life, as well as Earth's geologic history.
Published New Webb image reveals dusty disk like never seen before
(via sciencedaily.com) NASA's James Webb Space Telescope has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has been imaged at these infrared wavelengths of light. They also provide clues to the composition of the disk.
Published NASA's Webb confirms its first exoplanet
(via sciencedaily.com) Researchers confirmed an exoplanet, a planet that orbits another star, using NASA's James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth's diameter.
Published Scientists study life origins by simulating a cosmic evolution
(via sciencedaily.com) Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals. Because of amino acids' relationship to living things scientists are eager to understand the origins of these molecules. After all, amino acids may have helped spawn life on Earth after being delivered here about 4 billion years ago by pieces of asteroids or comets.
Published Origins of the building blocks of life
(via sciencedaily.com) A new study posits that interstellar cloud conditions may have played a significant role on the presence of key building blocks of life in the solar system.
Published The seven-year photobomb: Distant star's dimming was likely a 'dusty' companion getting in the way, astronomers say
(via sciencedaily.com) Astronomers were on the lookout for 'stars behaving strangely' when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn't changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, 'dusty' stellar companion.
Published Planetary system's second Earth-size world discovered
(via sciencedaily.com) Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.
Published The optical fiber that keeps data safe even after being twisted or bent
(via sciencedaily.com) An optical fiber that uses the mathematical concept of topology to remain robust, thereby guaranteeing the high-speed transfer of information, has been created by physicists.
Published The thermodynamics of quantum computing
(via sciencedaily.com) In research on quantum computers, one aspect that has been mostly neglected until now is the generation of heat. Physicists now focus their attention on heat as an interference factor -- and have developed a method to experimentally measure the heat generated by a superconducting quantum system.
Published Scientists find evidence for magnetic reconnection between Ganymede and Jupiter
(via sciencedaily.com) In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.
Published Hydrogen masers reveal new secrets of a massive star
(via sciencedaily.com) While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space.
Published Physicists confirm effective wave growth theory in space
(via sciencedaily.com) Physicists have used spacecraft data to confirm an important theory of plasma physics that improves our understanding of space weather.
Published New quantum computing architecture could be used to connect large-scale devices
(via sciencedaily.com) Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could be used to develop a large-scale network of quantum processors that could efficiently communicate with one another.
