    Sun-a-day diet for luminous quasar

    A heavyweight black hole, embedded within quasar SMSS J052915.80−435152.0 at a redshift of z ≈ 4, is accreting a solar mass of material every day. The process releases 2 × 1041 W of power, meaning that this quasar currently holds the title of most luminous quasar known.

    Four eyes see better than one

    Two thousand hours of observations split between four 25–32 m telescopes have produced a comprehensive overview of the high-energy radio emission from repeating fast radio burst source FRB 20201124A. The burst characteristics resemble those of non-repeating burst sources, suggesting a link.

    Gazing at galaxies from the edge of space

    SuperBIT is a wide-field, diffraction-limited optical and near-UV imager of the sky that was designed to travel via the seasonal winds at an altitude of 33 km. Suspended from a scientific balloon rather than a crane, its April 2023 mission took in views of merging galaxy clusters, galaxies, and massive star winds from the stratosphere.

    Habitability across geological timescales

    Habitability is usually defined for a specific time during a planet’s evolution. But how is that habitability sustained over billions of years? Comparing habitable conditions across different Solar System bodies is key to our understanding of the underlying processes driving long-term habitability.
