  • New “Super-Earth” Found in the Habitable Zone

    New “Super-Earth” Found in the Habitable Zone
    2025/11/01
    Astronomers have discovered GJ 251 c, a “super-Earth” nearly four times our planet’s mass, orbiting in its star’s habitable zone — the sweet spot for liquid water and possibly life. Using 20 years of data and tools like the Habitable-Zone Planet Finder, researchers from Penn State tracked the star’s subtle wobble to confirm the planet’s presence.

    While we can’t yet study its atmosphere, future telescopes may reveal whether GJ 251 c holds signs of alien life.

  • What’s Really Holding Back Space-Based Solar Power?

    What’s Really Holding Back Space-Based Solar Power?
    2025/10/30
    A new study reveals that the biggest barrier to space-based solar power isn’t in orbit—it’s on Earth. Researchers found that while thousands of satellites could technically beam solar energy from geostationary orbit, real-world factors like limited land for rectennas near the equator sharply reduce that number.

    Even so, the analysis shows SBSP could still provide up to 3% of global power, underscoring its potential as a future clean energy source.

  • How Cosmic Dust May Have Delivered the Building Blocks of Life to Earth

    How Cosmic Dust May Have Delivered the Building Blocks of Life to Earth
    2025/10/28
    In this episode, we explore new research from the Monthly Notices of the Royal Astronomical Society revealing how cosmic dust may have carried the building blocks of life to early Earth.

    Scientists simulated space conditions and found that amino acids like glycine and alanine could survive by clinging to silicate dust grains—tiny interstellar travelers that may have seeded our planet with the precursors for life.

    Tune in to uncover how these microscopic particles might have shaped Earth’s first chemistry.
