A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for various fields including x-ray generation and plasma physics. Think about atoms – the building blocks of everything around us. Sometimes, they lose their electrons and become charged particles (that’s ionization). It happens in lightning, in plasma TVs, and even in the northern lights. Until now, scientists thought they could only…
Lunar Magnetotelluric Sounder to characterize Moon’s mantle Just hours after touching down on the surface of the Moon on March 2 aboard Firefly Aerospace’s Blue Ghost 1 lander, the Southwest Research Institute-led Lunar Magnetotelluric Sounder (LMS) was activated and deployed its five sensors to study the Moon’s interior by measuring electric and magnetic fields. The LMS instrument is the first extraterrestrial application of magnetotellurics. “For more than 50 years, scientists have used magnetotellurics on Earth for a wide variety of…
Advancing the search for weird life on weird planets Scientists have identified a promising new way to detect life on faraway planets, hinging on worlds that look nothing like Earth and gases rarely considered in the search for extraterrestrials. In a new Astrophysical Journal Letters paper, researchers from the University of California, Riverside, describe these gases, which could be detected in the atmospheres of exoplanets — planets outside our solar system — with the James Webb Space Telescope, or JWST….
Gemini North’s MAROON-X instrument finds evidence for four mini-Earth exoplanets around our famous cosmic neighbor Barnard’s Star For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth [1]. Barnard’s Star is classified as a red dwarf — low-mass stars that often host closely-packed planetary systems, often with multiple rocky planets. Red dwarfs are extremely numerous in the Universe, so scientists…
University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old – just 2% of its current age. Observed by NASA’s James Webb Space Telescope, the galaxy – designated JADES-GS-z14-0 – is unexpectedly bright and chemically complex for an object from this primordial era, the researchers said. This provides a rare glimpse into the universe’s earliest chapter. The findings, published in the journal Nature Astronomy, build…
Computer simulations reveal how water separates into high-density and low-density liquids Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid underneath while storm clouds float overhead). It is also one of the only substances whose solid form is less dense than its liquid — this is why ice floats. Now scientists…
Cutting-edge observations of Centaurus Cluster shine new light on evolving universe The XRISM collaboration have discovered flows of hot gas in the core of the Centaurus Cluster. By comparing state-of-the-art X-ray measurements from the XRISM satellite with numerical simulations, they showed this is evidence for collisions between galaxy clusters, causing gas inside to “slosh”. This solves the longstanding mystery of how cluster cores stay hot, and sheds light on how our universe continues to evolve. Astronomers have long envisioned how…
EP’s cutting-edge instruments and international collaboration drive new discoveries in transient and multi-messenger astronomy The Science White Paper for the Einstein Probe (EP) mission has been published in Science China: Physics, Mechanics & Astronomy. This mission, spearheaded by the Chinese Academy of Sciences (CAS) in collaboration with the European Space Agency (ESA), the Max Planck Institute for Extraterrestrial Physics (MPE), and the French National Centre for Space Studies (CNES), is poised to advance the field of time-domain and X-ray astronomy…
New method to detect life makes Mars sample return protocols rock solid Within the next decade, space agencies plan to bring samples of rock from Mars to Earth for study. Of concern is the possibility these samples contain life, which could have unforeseen consequences. Therefore, researchers in this field strive to create methods to detect life. For the first time, researchers, including those from the University of Tokyo and NASA, successfully demonstrated a method to detect life in ancient rocks…
The discovery of a planet-forming disk much older than expected provides new insights into planet formation and the habitability of planets outside our solar system If there were such a thing as a photo album of the universe, it might include snapshots of pancake-like disks of gas and dust, swirling around newly formed stars across the Milky Way. Known as planet-forming disks, they are believed to be a short-lived feature around most, if not all, young stars, providing the raw…
Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research highlighted in a new paper, published today in The Astrophysical Journal, Scientia Senior Lecturer Ben Montet and PhD candidate Brendan McKee analysed changes in the timing of a known planet’s transit across its star, to infer the presence of a second exoplanet. After identifying an unusual trend in the…
The University of Basel and the University of Bern are setting up a new research center to enable the construction of superconducting quantum units. The Werner Siemens Foundation is supporting the project with a total of CHF 15 million over the next eleven years. The WSS Research Center for Molecular Quantum Systems is working on a pioneering technology set to lay the foundations for reliable and powerful quantum computers. This involves what are known as topological quantum bits (qubits), computing…
A new site for organic molecule formation? Niigata, Japan – Organic molecules that serve as the building blocks of life are believed to form in space, but their exact formation sites and delivery mechanisms to planets remain a major mystery in astronomy and planetary science. One of the key elements in solving this mystery is the presence of ice in interstellar environments. In cold, dense, and shielded regions of the galaxy, atoms and molecules adhere to the surfaces of submicron-sized…
Utah engineers create first flat telescope lens that can capture color while detecting light from faraway stars For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the bulkier and heavier they become. Scientists have long searched for a way to reduce the weight of lenses without sacrificing functionality. And while some slimmer alternatives exist, they tend to…
New breakthrough in miniaturized antennas promises enhanced performance for wireless communication in challenging environments A research team led by Professor Huizhu Hu from the Zhejiang University and Zhejiang Lab has developed a groundbreaking low-frequency receiving antenna using optically levitated nanoparticles, achieving a near 10,0000-fold reduction in size compared to conventional solutions. Published in PhotoniX on January 29, 2025, this innovation aims to address long-standing challenges in miniaturizing antennas for critical low-frequency (LF) communication scenarios such as underwater exploration, underground sensing, and ionospheric waveguides. Why It…
In March, NASA plans to launch its EZIE (Electrojet Zeeman Imaging Explorer) mission to learn more about auroral electrojets, intense electrical currents that flow through the upper atmosphere when auroras glow in the sky. High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on…
