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?
The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.
If some of the laws of physics were only infinitesimally different, we would simply not exist. It almost looks like the universe itself was built for life. But how can that be?
In about 10100 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.
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?
Twenty-five years on and the Hubble Space Telescope is still taking some amazing images. But there have been a few glitches over the years, right from day one.

What happens to a galaxy when it runs out of the stuff needed to forge new stars?
More than 100 million years has been wiped off the age of the first stars but there is still the question of what happened in the first billion years of the universe. Earlier this month the European Space…
The universe is such a big place that it is easy to get baffled by the measurements that astronomers make. The size of UY Scuti, possibly one of the largest stars we have observed to date, is certainly…
