The expanding universe.
New research out this month has led to speculation that the acceleration of the expanding universe might not be real after all. So what's really going on?

Dark energy is a completely unknown source making up 70% of the universe. Will any of the new projects designed to find out what it is succeed?
Black holes will be all that remains before the universe enters heath death. But the story doesn’t end there…
In about 10^100 years, the universe will have passed away in a tragic 'heat death'. But don't despair, eventually random conscious brains may pop out in empty space to shake things up.

Our universe's most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
How do we think about something we can’t see and don’t experience in our everyday lives, but seems to be pushing our universe apart ever faster?

Einstein's theory of gravity says dark energy must be out there, accelerating the expansion of our universe. But what is it and how can we try to figure out more about it?
Research of a supernova in our galaxy will increase the precision of which we can measure distances outside of our own galaxy…
