Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim

Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating and that this is driven by “dark energy” arising from the quantum vacuum. Their letter has been published in Monthly Notices of the Royal Astronomical Society.

Are asteroid-mass black holes hiding in the cosmic gamma-ray glow?

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there is another class of black holes, known as primordial black holes (PBHs), that could have been created immediately after the Big Bang by matter collapsing in on itself. Or that’s the theory, at least. Though long theorized, we’ve never actually seen one of them, though scientists have suggested that they might account for the missing mass of the universe, which we otherwise describe as “dark matter.”

Astronomers map a magnetic ‘skeleton’ funneling gas into a stellar nursery

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this process—and a leading suspect has been the role of magnetic fields, which thread through interstellar gas like an invisible scaffolding.

Astronomers want to build a swarm of telescopes to find life

Current plans for flagship telescopes in the 2040s are focused on answering a simple question: Are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST), have given us only tantalizing glimpses into the atmospheres of other worlds, but not enough to truly determine whether life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.

Webb spots the birth of a giant galaxy and a supermassive black hole

Astronomers have used the James Webb Space Telescope to catch an extraordinary glimpse of a massive galaxy taking shape in the early universe. They identified a compact group of at least six galaxies that are likely to merge into a single enormous system. At the heart of this cosmic construction site lies a growing supermassive black hole.

Room-temperature device synchronizes distant laser spots into single coherent ‘supermode’

Researchers have demonstrated a new way to make spatially separated lasers synchronize and act as a single coherent light source—without extreme conditions or complex materials.

A minimal model for how a cell takes shape from the inside

Researchers at the University of Twente and Utrecht University have packed rigid, rod-shaped particles into soft lipid containers the size of a living cell and watched the container and its contents reshape each other. The vesicle’s form determines how the rods line up; the tightly packed rods, in turn, bend the container into new shapes. This provides a minimal model for how physical coupling between a soft boundary and internal filaments can help cellular structures organize from within. The paper is published in the Proceedings of the National Academy of Sciences.

Modeling nuclear fusion at lightning speed

As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into nuclear fusion research. The hope is that fusion may ultimately provide a virtually limitless source of clean energy.

Broken time-reversal symmetry phase in kagome metals may establish conditions for superconductivity

Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute of Science and Technology has performed experiments on a kagome metal that provide the strongest evidence yet for this exotic state.

Titan and Pluto exhibit the same mysterious spectral feature—and researchers can’t figure out its origin

Researchers are constantly sifting through new spectral data gathered by powerful telescopes, like the James Webb Space Telescope (JWST). Most of the time, when they identify spectral features—specific absorption or emission lines from different types of light gathered from a planet, moon or star—these features are known to be caused by certain atoms or molecules. For example, the emission line at 426.7 nanometers is known to come from singly ionized carbon, representing a specific atomic transition between energy states of a carbon ion.
