    With proposed missions to Mars and plans to establish outposts on the Moon in the coming decades, there are several questions about what effects time spent in space or on other planets could have on the human body. Beyond the normal range of questions concerning the effects of radiation and lower-g on our muscles, bones, and organs, there is also the question of how space travel could impact our ability to reproduce.
    Earlier this week – on Monday, May 22nd – a team of Japanese resear
  • New Ideas for the Mysterious Tabby’s Star: a Gigantic Planet or a Planet With Rings

    KIC 8462852 (aka. Tabby’s Star) captured the world’s attention back in September of 2015 when it was found to be experiencing a mysterious drop in brightness. A week ago (on May 18th), it was announced that the star was at it again, which prompted observatories from all around the world to train their telescopes on the star so they could observe the dimming as it happened.

    Sterrenkundigen hebben met behulp van drie grote telescopen – de Hubble ruimtetelescoop, de Spitzer infrarood-ruimtetelescoop en op aarde de Large Binocular Telescope (LBT) – in een ander sterrenstelsel een stervende ster ontdekt, die zonder daverende explosie als supernova als een nachtkaars uitging en wiens kern tóch vervolgens een zwart gat vormde. Het gaat om de ster genaamd N6946-BH1,

  • NASA Moves Up Mission to Metal Asteroid Psyche

    This illustration depicts the spacecraft of NASA’s Psyche mission orbiting the metal asteroid Psyche (pronounced SY-kee). Solar power with electric propulsion will be used to propel the spacecraft to Psyche. The asteroid’s average distance from the sun is about three times the Earth’s distance or 280 million miles.

    I’m getting psyched for Psyche, which is both the name of an asteroid orbiting the sun between Mars and Jupiter and N
