When does the line between day and night become vertical? Tomorrow. Tomorrow is an equinox on planet Earth, a time of year when day and night are most nearly equal. At an equinox, the Earth's terminator -- the dividing line between day and night -- becomes vertical and connects the north and south poles.

The above time-lapse video demonstrates this by displaying an entire year on planet Earth in twelve seconds.

From geosynchronous orbit, the Meteosat satellite recorded these infrared images of the Earth every day at the same local time. The video started at the September 2010 equinox with the terminator line being vertical. As the Earth revolved around the Sun, the terminator was seen to tilt in a way that provides less daily sunlight to the northern hemisphere, causing winter in the north. As the year progressed, the March 2011 equinox arrived halfway through the video, followed by the terminator tilting the other way, causing winter in the southern hemisphere -- and summer in the north.

The captured year ends again with the September equinox, concluding another of billions of trips the Earth has taken -- and will take -- around the Sun.

The book, edited by Christopher Tolkien, will also include the series of lectures Tolkien gave at Oxford about the poem in the 1930s, as well as the author's "marvellous tale", Sellic Spell.

Seven for the week to drink in my halls all alone
Nine for the week after or I'll be doomed to die
One semi-skimmed for Mother on her throne
In the living room where the shadows lie
One milkman to rule them all, one milkman to find them
One milkman to bring them all and in the darkness deliver them
In the land of Oxford where the shadowy living rooms lie

Tease.
