  • A new five-year survey of the Magellanic Clouds will answer some questions about our neighbors

    The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their close proximity makes them excellent laboratories for the study of galaxies in general. The Clouds are the focus of a new research group being formed at the Leibniz Institute for Astrophysics Potsdam (AIP).

  • Neutron star P13 shows dramatic X-ray variability linked to rotation velocity

    A research team has investigated long-term X-ray variability in the neutron star NGC 7793 P13, an object thought to be driven by supercritical accretion, where an extraordinary amount of gas falls onto the object and emits intense X-rays. The team found a relation between the X-ray luminosity and the rotation velocity, which could provide clues to reveal the supercritical accretion mechanism.

  • Supernova immersion model suggests Earth-like planets are more common in the universe

    Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a nearby supernova (the massive explosion of a star near the end of its life) bathed it in cosmic rays containing the radioactive ingredients to make rocky, dry worlds. This mechanism could be ubiquitous across the galaxy.
