Webb spots clues of a black hole at the heart of nearby galaxy M83

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising finding, made possible by Webb’s Mid-Infrared Instrument (MIRI), reveals highly ionized neon gas that could be a telltale signature of an active galactic nucleus (AGN), a growing black hole at the center of a galaxy.

Astrophysicists solve the mystery as to why some meteorites look less shocked

Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

Dark matter search: Dimming starlight may signal passage of dark compact objects

The detection of dark matter, an elusive form of matter believed to account for most of the universe’s mass, remains a long-standing goal within the physics research community. As this type of matter does not emit, reflect or absorb light, it cannot be observed using conventional telescopes and experimental methods.

Nanophotonic platform boosts efficiency of nonlinear-optical quantum teleportation

Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes could not operate with the extremely low light levels required for quantum communication.

Video game-inspired algorithm rapidly detects high-energy particle collisions for future fusion reactors

An innovative algorithm for detecting collisions of high-speed particles within nuclear fusion reactors has been developed, inspired by technologies used to determine whether bullets hit targets in video games. This advancement enables rapid predictions of collisions, significantly enhancing the stability and design efficiency of future fusion reactors.

Direct lab observation reveals key mechanism behind cosmic particle acceleration

Researchers from the University of Science and Technology of China (USTC) achieved the first direct laboratory observation of ion acceleration through reflection off laser-generated magnetized collisionless shocks. This observation demonstrates how ions gain energy by bouncing off supercritical shocks, central to the Fermi acceleration mechanism. The research is published in Science Advances.

High-pressure electron tunneling spectroscopy reveals nature of superconductivity in hydrogen-rich compounds

Scientists have achieved a major milestone in the quest to understand high-temperature superconductivity in hydrogen-rich materials. Using electron tunneling spectroscopy under high pressure, the international research team led by the Max Planck Institute for Chemistry has measured the superconducting gap of H3S—the material that set the high-pressure superconductivity record in 2015 and serves as the parent compound for subsequent high-temperature superconducting hydrides.

Why Webb may never be able to find evidence of life on another world

The exoplanet K2-18b is generating headlines because researchers announced what could be evidence of life on the planet. The JWST detected a pair of atmospheric chemicals that on Earth are produced by living organisms. The astronomers responsible for the results are quick to remind everyone that they have not found life, only chemicals that could indicate the presence of life. The results raise a larger question, though: Will the JWST really ever detect life?
