  • Einstein’s Law and the Dearth of Two-Sun Planets

    Einstein’s Law and the Dearth of Two-Sun Planets
    Feb 3 2026
    New astrophysical research suggests that general relativity helps explain why planets are rare in binary star systems. As close stellar pairs evolve, relativistic orbital effects create resonances that destabilize nearby planetary orbits.

    The result is a hostile environment where planets are either ejected or destroyed, leaving a planetary “desert” around tight binaries. Only distant worlds can survive—often too far away to be easily detected.

  • A Dark Matter Sheet Shapes the Motion of the Milky Way

    A Dark Matter Sheet Shapes the Motion of the Milky Way
    Feb 1 2026
    New research suggests the Milky Way and Andromeda lie within a vast, flat sheet of dark matter stretching millions of light-years. Using detailed computer simulations, scientists explain puzzling galaxy motions that once seemed to defy gravity.

    This planar structure—bounded by enormous cosmic voids—allows nearby galaxies to follow the universe’s expansion despite strong local gravity, bringing theory and observation into rare alignment in our cosmic neighborhood.

  • Did Earth’s Water Come from Space? New Clues from Lunar Samples

    Did Earth’s Water Come from Space? New Clues from Lunar Samples
    Jan 30 2026
    This episode examines new evidence from Apollo-era lunar samples suggesting that most of Earth’s water did not come from asteroid or comet impacts.

    By studying oxygen isotopes preserved on the Moon’s stable surface, researchers found that meteoritic contributions were surprisingly small.

    These findings challenge long-standing theories about the origin of Earth’s oceans, while offering new insight into how our planet became habitable—and how lunar resources could s
