Are cell mutations always bad? A mutation is a change in the genetic material of an organism. We are made from trillions of cells, each with a nucleus composed of DNA â a set of instructions that tells the cell what to do. Cells copy themselves with astonishing accuracy, but every now and then a piece of code is copied incorrectly.
Seven eclipses occur in a minimum of 12 lunar months (about 354.37 days). Given that the calendar year is only about eleven days longer than 12 lunar months, the first of the seven eclipses has to come in early January for the seventh eclipse to occur before the end of the year.
In Australia and eastern Asia, the eclipse will occur in late evening or near midnight local time, and this is where the moon will be highest in the sky. The year's next eclipse will be on the night of July 27, or the wee hours of July 28 depending on the time zone, and the center of the eclipse visibility region is on the Indian Ocean.
