  • Researchers released studies on the composition of the interstellar comet 2I/Borisov.
  • The 'pristine' comet holds clues to the origins and evolution of the Solar System.
  • The comet, discovered in 2019, is only the second interstellar object ever observed.

    • Researchers discovered a route through the Solar System that can allow for much faster spacecraft travel.
    • The path takes advantage of "arches of chaos" within space manifolds.
    • The scientists think this "celestial superhighway" can help humans get to the far reaches of the galaxy.

    New model explains Saturn’s hexagon shaped storm

    The solar system has some strange stuff in it. Learning how it ended up that way can tell us where we're going.

    • A new model of Saturn's atmosphere might finally explain how a bizarrely shaped storm developed there.
    • The model produced a polygonal storm system similar, but not identical to, that observed on Saturn.
    • The findings may shed light on the formation of the solar system.

    This meteorite was here before Earth existed. Here's why it matters.

    This meteorite is the oldest known volcanic rock in the solar system, dated at 4,565,000,000 years old.

    • It's very rare that we discover something on our planet that was around before we were even a small speck. But every once in a while, we do—and this meteorite is a living testament.
    • Scientists estimate the new discovery to be approximately 4.6 billion years old, almost as old as the solar system itself.
    • New discoveries like this one bring us a small step closer in piecing together what an earlier version of Earth might have looked like.

    Scientists discover ice volcanos on Ceres

    Cryovolcanoes that eject ice instead of magma have been confirmed to exist on Ceres, which will help studying this formation on other planets and moons throughout the solar system.

    • Cryovolcanoes that ooze out ice instead of shooting out magma have been confirmed to exist on the asteroid Ceres.
    • Scientists believe that ice volcanoes may be prevalent throughout the solar system in places like Titan and Pluto.
    • Further research is needed to find out if they serve an important function for planetary structure and exo geological systems.
