Different measures of the rate of the Universe’s expansion give different results – and a new measurement technique only makes matters more complicated.

The enigma at the centre of our 20-year collaboration was how the Big Bang could have created conditions so perfectly hospitable to life
A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
For decades physicists have argued over the nature of the elusive dark matter that pervades the Universe. A clever new study uses gravitational lensing to bring new evidence to the debate.
The current race to the Moon is opening up opportunities for lunar astronomy.
Some physicists think we live in a multiverse, surrounded by universes not quite like our own. What does that mean for life?
To date, we have not heard from any aliens. Nor have we seen any – but here are the fascinating projects working to change that.
The discovery of massive, early galaxies could force scientists to rethink how the first galaxies formed after the Big Bang.
Astronomers have detected a radio glow caused by shockwaves in the gigantic filaments between galaxy clusters in the ‘cosmic web’ which pervades the Universe.
Astronomers have found that mysterious dark energy may originate in black holes.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
Our galaxy should be full of traces of dead stars. Until now, we have found surprisingly few of these supernova remnants, but a new telescope collaboration is changing that.
To understand this question, we need to travel back in time.
A year on since the historic launch of the most powerful infrared telescope in human history, we admire and explore some of the best images it delivered in 2022.
There may be ways to check if our universe is just simulated entertainment for an advanced, alien species.
The theory of gravity may need to be altered.
There’s a curious 200-million-year rhythm to Earth’s crust production. Now, it seems like our very place in the galaxy is tied to it.
There’s a perfectly good alternative to dark matter, but most scientists aren’t keen on the idea.
The jazz star says he wants his piano to speak in his isiZulu language, and that his music is born from spiritual concerns.
Scientists have come up with a number of theories about the multiverse.
