As we enter the longest day of the year, Google throws up a fun Doodle that reminds us that we all wish we were chilling out poolside right now.If you’re in the northern hemisphere, today marks the 2013 Summer Solstice. The Sun will be above the horizon for longer than any other day of the year, possibly up to 16 hours above your head. This is the highest Sun of the year, and the mark that Summer has officially started in many parts of the world. The North Pole is tilted more towards the Sun today than any other day of the year, which is why we get that extra bit of sunlight today.In celebration of this, one of Google’s many Doodles is sitting on their homepage, reminding you that you are not currently sitting in a pool or enjoying the beach.This year’s Summer Solstice is a little different from the others, as it is also the start of a weekend that will end with the SuperMoon. This is the one moon phase of the year that our celestial satellite will be larger and brighter than any other night of the year. Most times this is imperceptible to the human eye, and for these two events to happen within such proximity is purely coincidence, but it gives you an extra reason to look up at the sky this Sunday night.
