New Scars Found on Moon: The largest of the newly found graben, in highlands on the moon’s far side.

Parts of the moon’s surface have been stretched apart to form shallow, sunken valleys, according to a new study based on NASA images.
The presence of the long, thin valleys—known as graben—suggests that the moon has undergone relatively recent tectonic activity, within the past 50 million years or so.
That activity in turn hints that the moon may not have been entirely melted when it first formed roughly 4.6 billion years ago. Instead the early moon likely had a solid core covered by a global ocean of molten rock.

 Hitoshi Nomura made ‘Moon  Scores’ between 1975 and 1979, the project consisted to take photographs  from the lunar body moving across the night sky.  Nomura marked  the film  with five lines, turning the photographs series into an item  of musical notation. Transferring the notes to staff paper, he then had  the chance compositions performed by a chorus and a string quartet.
