A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
Most astronomers believe the universe is 13.7 billion years old. A new study says that figure could be closer to 26.7 billion.

This is a timeline of the Universe from the Big Bang to the heat death scenario. The different eras of the universe are shown. The heat death will occur in around 1.7×10 106 years, if protons decay .
The universe was only 630 million years old when the GRB occurred, and its detection confirms that massive stars were born and dying even very early on in the life of the universe. GRB 090423 and similar events provide a unique means of studying the early universe, as few other objects of that era are bright enough to be seen with today's ...
