Aurora Borealis !!
Why wait for the Northern Lights (otherwise known as aurora borealis) when it can come to your bedroom every night? Japanese company Banpresto is offering its Aurora Palette gadget to the US. It projects different atmospheric light on your ceiling or wall, creating a relaxing environment while you fall asleep. It's shaped like an oversized pill and sits upon a base. It lasts for about 20 hours on 4 AA batteries and can be set to operate for 30, 60, 90, or 120 minutes at a time. Watch the YouTube video to see the Aurora Palette in action.
An aurora (plural aurorae/auroras) is an Electro-static phenomenon, characterised by a bright
glow and caused by the collision of charged particles in the magnetosphere with atoms in the Earth's upper atmosphere. An aurora is usually observed in the night sky, particularly in the polar zone. For this latter reason, some scientists call it a "polar aurora" (or "aurora polaris"). http://en.wikipedia.org/wiki/Aurora_(astronomy)
