People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
In part two of our podcast on rebooting, we explore what would happen if humanity was wiped out, take a look at a political comeback in France, and get a taste of a revamped US institution.
This month marks the 50th anniversary of the discovery of the Cosmic Microwave Background, which is the radiation left over from the birth of the universe.
Subatomic particles have shaped and continue to shape our universe but despite perfect predictions by physicists, the theory about unseen particles is still wrong.
Several dwarf galaxies have been discovered close to our own Milky Way and are adding to our understanding of how galaxies form. But why haven’t astronomers seen them before?
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…
One of this century’s greatest potential discoveries concerning the origins of the universe has now fallen to galactic dust. That’s according to a new joint-analysis of all the existing data – including…
Recent observations suggest that there is something not quite right with our view of our universe – that something is skewing our view of the oldest radiation arriving at our telescopes. What’s causing…
It’s almost three months since a team of scientists announced it had detected polarised light from the afterglow of the Big Bang. But questions are still being asked about whether cosmic dust may have…
Scientists at the Harvard-Smithsonian Centre for Astrophysics in the US have announced overnight what they believe is the indirect detection of gravitational waves in the afterglow of the Big Bang. The…
The cosmological community is bubbling with the news that the BICEP2 experiment may have detected gravitational waves through measuring the radiation left over from the big bang. If the findings are correct…
The discovery of an ancient star formed approximately 13.6-billion years ago just after the Big Bang is telling us much about the early universe. The star – designated SMSS J031300.36-670839.3 – lies within…
According to cosmologists, galaxies are joined together by filaments, quite literally. These filaments form the cosmic web and are made of mostly dark matter, many stars and some gas. Observing these filaments…
