Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of any known objects, surpassed only by black holes. First observed in the 1960s, much of the internal composition of neutron stars is still unknown. Scientists are beginning to look to gravitational waves emitted by binary neutron‐star inspirals—pairs of mutually orbiting neutron stars—as possible sources of information about their interiors.
Physicists at the University of Illinois Urbana-Champaign, together with colleagues at the University of California, Santa Barbara, Montana State University, and the Tata Institute of Fundamental Research in India have made a major theoretical breakthrough in understanding how inspiraling binary neutron stars respond to tidal forces, a key step in elucidating neutron stars’ makeup. The team has proven that the time‐dependent tidal responses of such stars can be described in terms of their oscillatory behavior, or modes, extending an analogous result from Newtonian gravity to the relativistic setting.
This research was published as an Editors’ Suggestion in the journal Physical Review Letters on February 18, 2026, and paves the way to probing the internal structure of neutron stars and some of nature’s most extreme types of matter using gravitational waves.
Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the possibility that our reality contains extra dimensions
Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination between instruments. The teams that run the James Webb Space Telescope (JWST) and the upcoming Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) missions will have plenty of opportunity for that once both telescopes are online in the early 2030s. A new paper, available in pre-print on arXiv, from the Ariel-JWST Synergy Working Group details just how exactly the two systems can work together to better analyze exoplanets.
JWST has already been at the center of media attention since even before its launch in late 2021. It is currently the most capable of our space-based observatories, but it is a multi-purpose tool that has a long line of scientists waiting to get time on it.
Capable of observing everything from far-away black holes to interstellar comets passing through our own solar system, JWST has absurdly high resolution but lacks the sheer amount of time it takes to observe some exoplanets fully. In addition, in some cases it’s too sensitive, as exceptionally bright stars, which are great for observing exoplanet atmospheres, are powerful enough to saturate the detectors on JWST, making it useless to track exoplanets orbiting those types of stars.
Space is huge, immense beyond our wildest dreams. In order to explore and settle it, we’ll need to learn to dream a lot bigger and bolder than ever before.
Have you ever felt like the world around you isn’t exactly… “real”? Modern physics is starting to suggest something incredible: The universe isn’t made of atoms, energy, or particles. It is made of Information. In this video, we explore the radical “It from Bit” theory and the Holographic Principle. From the mysterious paradoxes of Black Holes and Hawking Radiation to the way quantum entanglement might actually create the fabric of space and time, we dive deep into the mind-bending reality of quantum mechanics. In this video, we cover: Why Stephen Hawking conceded the Black Hole Information Paradox. The Ryu-Takayanagi formula: How entanglement builds geometry. Why 3D space might just be a 2D holographic projection. The “It from Bit” philosophy by John Wheeler. How consciousness relates to Integrated Information Theory (IIT). If reality is just a pattern of qubits in a vast Hilbert space, what does that make us? Join us as we deconstruct the material world and look at the “source code” of the universe. #QuantumPhysics #HolographicUniverse #ItFromBit #TheoreticalPhysics #ScienceDocumentary #SpaceTime #quantuminformation
Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story
A viral post claimed that a mysterious force passed through the Milky Way without light or warning. But what are astronomers actually observing? In this video, we break down the real science behind high-velocity gas clouds, dark matter halos, and how our galaxy continues to evolve.
