• Space Debris Hits Window Of ISS Causing Tiny Crack

    As we have done to Earth, now we are doing to space! We have polluted our home planet beyond recognition, now we are polluting space. Well that’s a little unsettling. Astronaut Tim Peake took to Twitter to share an image of a 7-mm crack in the window of the Cupola module of the International Space Station, caused by a bit of what he called “space debris.” Enjoy and share……….

  • Supernova or Gamma Ray Burst?

    WR 104: Looking down the barrel What if a Gamma Ray Burst hit Earth? This is what you would see: “You would first notice a 10-second blue flash in the upper atmosphere,” said Melott, “but then the damage would be done.” Although WR 104, a Wolf-Rayet star some 8000 light years distant, has thus far remained largely quiescent, it is ripe to undergo a core-collapse supernova of the sort that could generate a seconds-long burst of gamma-rays that, in turn, […]

  • The Stunning Highs and Lows of Mercury

    Data from NASA’s MESSENGER mission have been used to create this animation of the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize its geologic history. Mercury’s surface is colored according to the topography of the surface, with regions with higher elevations colored brown, yellow, and red, and regions with lower elevations shown in blue and purple. The MESSENGER spacecraft was […]

  • The unique rocky comet C/2014 S3

    Observations with ESO’s Very Large Telescope, and the Canada France Hawai`i Telescope, show that C/2014 S3 (PANSTARRS) is the first object to be discovered that is on a long-period cometary orbit, but that has the characteristics of a pristine inner Solar System asteroid. It may provide important clues about how the Solar System formed. This video shows the probable history of this object in both the inner and outer Solar System over a period of more than four billion years. […]

  • Three Potentially Habitable Worlds

    Three Potentially Habitable Worlds Found Around Nearby Ultracool Dwarf Star Currently the best place to search for life beyond the Solar System Astronomers using the TRAPPIST telescope at ESO’s La Silla Observatory have discovered three planets orbiting an ultracool dwarf star just 40 light-years from Earth. These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the Solar System. They are the first […]
