  • How NASA’s Nancy Grace Roman Space Telescope Will Detect Invisible Neutron Stars

    How NASA’s Nancy Grace Roman Space Telescope Will Detect Invisible Neutron Stars
    2026/05/30
    The Nancy Grace Roman Space Telescope will use gravitational microlensing to detect isolated neutron stars normally invisible to telescopes.

    By tracking subtle distortions in starlight, astronomers hope to measure their masses, uncover hidden stellar remnants across the Milky Way, and better understand the boundary between neutron stars and black holes.

  • Inside the Chaotic Evolution of Giant Black Holes

    Inside the Chaotic Evolution of Giant Black Holes
    2026/05/29
    Using gravitational wave data, researchers identified two populations of Black holes: smaller ones formed from collapsing stars and heavier ones created through repeated mergers in dense star clusters.

    The findings support the existence of a black hole “mass gap” and reveal how chaotic collisions shape the largest black holes in the universe.

  • Celestial Architects: Mapping the Universe's Winged Radio Galaxies

    Celestial Architects: Mapping the Universe's Winged Radio Galaxies
    2026/05/28
    Astronomers using LOFAR identified more than a thousand rare winged radio galaxies with X- and Z-shaped structures formed by jets from supermassive black holes.

    The discoveries provide new insight into how these jets shift over time, interact with intergalactic space, and shape the long-term evolution of galaxies.

  • Solar Storms Are Pulling Satellites Out of Orbit Faster Than Expected

    Solar Storms Are Pulling Satellites Out of Orbit Faster Than Expected
    2026/05/27
    New research shows that when solar activity intensifies, emissions from the Sun heat and expand Earth’s atmosphere, increasing drag on objects in orbit.

    This accelerates the fall of space debris and satellites, especially beyond a critical activity threshold. The findings reshape how operators plan fuel, avoid collisions, and manage long-term traffic in low Earth orbit.

  • Inside the Turbulent Birthplaces of Stars

    Inside the Turbulent Birthplaces of Stars
    2026/05/26
    Astronomers analyzed over 100,000 molecular clouds to uncover how stars form across galaxies. These stellar nurseries turn out to be short-lived, turbulent structures, with only a small fraction of their gas becoming stars before feedback disperses them.

    The results reveal a self-regulating cycle shaped by galactic environment, offering a new, unified view of how galaxies evolve over time.

  • From Atmospheres to Surfaces: JWST’s New Exoplanet Breakthrough

    From Atmospheres to Surfaces: JWST’s New Exoplanet Breakthrough
    2026/05/25
    Using infrared observations from the James Webb Space Telescope, astronomers have inferred the surface composition of LHS 3844 b.The planet appears to be a hot, airless super-Earth with a dark, basaltic surface and no signs of Earth-like tectonics, likely covered in radiation-processed dust.

    The result marks a shift from studying exoplanet atmospheres to directly probing their geology.

  • POET Mission: Finding Planets Around Ultracool Stars

    POET Mission: Finding Planets Around Ultracool Stars
    2026/05/24
    Canada’s upcoming POET micro-satellite mission, set for a 2029 launch, aims to detect Earth-sized and super-Earth planets orbiting ultracool dwarf stars using transit photometry.

    By monitoring tiny dips in starlight, the mission will scan a curated list of over 3,000 nearby stars, leveraging a larger telescope and a wide wavelength range from ultraviolet to infrared.

    The goal is to identify habitable-zone candidates that can later be studied for atmospheric biosignatures with the James Webb Space Telescope, advancing the search for potentially life-supporting worlds.
