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 »

I am an astrophysicist who has mapped the universe with data from the Chandra X-ray Observatory; Clear, sharp photos help me study energetic black holes

When a star is born or dies, or any very energetic event occurs in the universe, it emits X-rays, which are high-energy particles of light invisible to the naked eye. These x-rays are the type doctors use to take pictures of broken bones in the body. But instead of looking at the shadows cast by… Read More »

Largest 3D map of our universe may hint that dark energy is evolving over time

More than twenty years have passed since the discovery of dark energy. So scientists have had more than 20 years to unravel the secrets of this invisible substance that seems to tear the universe apart. But still they know almost nothing about it. In fact, dark energy may not even be a substance. This could… 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 »

‘Stirring’ of energy waves on Earth may hold history of the universe

By measuring how energy waves move through the sky above Earth, scientists have created a way to delve into the 13.8 billion-year history of our universe, starting from “first light.” The team, led by Johns Hopkins University astrophysicists, used an array of microwave telescopes called the Cosmology Large Angular Scale Surveyor (CLASS) to map 75%… Read More »

James Webb Space Telescope detects dwarf galaxies powerful enough to reshape the entire early universe

Astronomers used the James Webb Space Telescope (JWST) and estimated this effect Albert Einstein More than 100 years ago, we discovered that small galaxies in the early universe had a massive impact that shaped the entire universe when it was less than 1 billion years old. The international team found that galaxies similar to the… 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 »
