   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

           TYC 8998-760-1: Multiple Planets around a Sun Like Star

   Explanation: Do other stars have planets like our Sun? Previous
   evidence shows that they do, coming mostly from [6]slight shifts in the
   star's light created by the orbiting planets. [7]Recently, however, and
   for the first time, a pair of [8]planets has been directly imaged
   around a Sun-like star. These [9]exoplanets orbit the star designated
   [10]TYC 8998-760-1 and are identified by arrows in the [11]featured
   infrared image. At 17 million years old, the parent star is much
   younger than the 5-billion-year age of our Sun. Also, the
   [12]exoplanets are both more massive and orbit further out than their
   [13]Solar System analogues: [14]Jupiter and Saturn. The exoplanets
   [15]were found by the [16]ESO's [17]Very Large Telescope in [18]Chile
   by their [19]infrared glow - after the light from their parent star was
   [20]artificially blocked. As [21]telescope and [22]technology improve
   over the next decade, it is [23]hoped that planets more [24]closely
   resembling our [25]Earth will be directly imaged.

    Experts Debate: [26]How will humanity first discover extraterrestrial
                                    life?
