Some of the earliest galaxies found with JWST are also the brightest. That’s a problem for our ideas about the universe.
We may be on the cusp of finally breaking the standard model of cosmology.
The Hubble tension has been described as a “crisis” for cosmology. Can it be resolved?
A new series delves into the big questions surrounding the nature of our universe.
Right now, it looks like cosmology is at a tipping point.
Cosmology does not need dark matter or dark energy in an expanding universe that allows the constants of nature to evolve, and light loses energy as it travels vast distances.
After a decade studying thousands of supernovae, astronomers are still perplexed by the enigma that led Einstein to his ‘greatest mistake’.
The nature of dark energy remains one of the biggest puzzles in cosmology.
If we lived in a cosmic area with below average density, it would explain recent contradictory measurements of the universe’s expansion.
The universe is expanding faster than physicists would expect. To figure out what processes underlie this fast expansion rate, some researchers are first trying to rule out what processes can’t.
The universe appears to be fine-tuned for life to evolve.
From improving our understanding of dark matter to revealing the location of Earth 2.0, the Extremely Large Telescope promises answers to some of the biggest scientific questions of our time.
The Euclid mission is preparing to launch on July 1.
A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
Astronomers have found that mysterious dark energy may originate in black holes.
Australian astronomers are part of a prize-winning team that was the first to pinpoint the location of a fast radio burst. But there is much we still don’t know about these mysterious bursts.
Dark energy is probably a sea of constant energy in empty space itself, according to new research.
More than 70% of the Universe is made of ‘dark energy’, the mysterious stuff even stranger than dark matter

Today on the podcast, we explore what we know about dark energy, believed to be responsible for the acceleration of the expansion of the Universe.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
