Astronomers need their measurements of type Ia supernovae to be precise in order to correctly measure the expansion of the universe
Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe’s expansion rate.
Signals from rare black hole-neutron star pairs could pinpoint rate at which universe is growing
Gemma Lavender heads straight into this one to find us the answer.
We gave Josh Barker from the National Space Centre the big job of answering this one.
