   Explanation: [8]Today's solstice brings summer to planet Earth's
   northern hemisphere. But the northern summer [9]solstice arrived for
   ringed planet Saturn over three years ago on May 24, 2017. [10]Orbiting
   the gas giant, Saturn's moon Titan experiences the [11]Saturnian
   seasons that are about 7 Earth-years long. Larger than inner planet
   Mercury, Titan was captured in this [12]Cassini spacecraft image about
   two weeks after its northern summer began. The near-infrared view finds
   bright methane clouds drifting through Titan's dense, hazy atmosphere
   as seen from a distance of about 507,000 kilometers. Below the clouds,
   dark [13]hydrocarbon lakes sprawl near its fully illuminated north
   pole.
