NGC 3972, located 66 million light-years away in the constellation Ursa Major, was one of 10 galaxies used to measure the expansion of the universe in a new study. | Credit: Yuval Harpaz, data via JWST Observations by the… Read More »

Can the James Webb Space Telescope see galaxies beyond the universe’s horizon?

The James Webb Space Telescope (JWST) has made a huge impact on astronomy since it began sending data back to Earth in 2022, and one of its most revolutionary achievements has been the observation of some of the most distant galaxies ever seen. But because light doesn’t travel instantaneously — instead, it travels at about… Read More »

Strange physics at the edges of black holes could help solve the ongoing ‘Hubble problem’

The universe’s expansion rate is accelerating across the cosmos, driven by a mysterious force known as dark energy, but perhaps this acceleration isn’t happening at the boundaries of black holes, new research suggests. Rather than implying that dark energy does not move around the boundaries of black holes, this idea suggests that this mysterious force… Read More »

Euclid ‘dark universe’ telescope team to unveil new full-colour images on May 23: How to watch live

The European Space Agency (ESA) will release five new images from the Euclid space telescope on Thursday, May 23. And if the previous batch of photos is anything to go by, space fans should be in for an absolute treat. “Five new portraits of our universe were captured during Euclid’s first observations, each revealing surprising… Read More »

Mysterious ‘particleless particles’ may be tearing the universe apart, new theoretical study suggests

A new theoretical paper suggests that the accelerating expansion of the universe may be driven by a mysterious form of matter called “particleless” that does not fit the Standard Model of particle physics. Scientists widely accept that the universe is expanding, but the reason for this expansion remains unclear. One of the most popular explanations… Read More »

What is the great rip and can we stop it?

Imagine a future in which the universe will fall apart very soon. Eventually space-time breaks apart, making the universe uninhabitable. Imagine a future in which the universe will fall apart very soon. First come the clusters whose galaxies are moving away from each other. Later galaxies solve it. Then star systems and planets. And then… Read More »

Decade-long Dark Energy Survey provides new insight into the expansion of the universe

Surveys of more than 1,500 supernovae conducted by the Dark Energy Camera have established strong constraints on the accelerating expansion of the universe. The results show that the mysterious force driving this cosmic acceleration, dark energy, can change in density over time, challenging the standard model of cosmology. Relating to: Dark energy remains a mystery… Read More »
