Experience suggests that we perceive distances linearly. However, the actual geometry of spatial representation in the brain is unknown.

Above the atmosphere is space. It’s called that because it has far fewer molecules, with lots of empty space between them.

New measurements show that the light emitted by stars outside our galaxy is two to three times brighter than the light from known galaxies.

A new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty.

Astrophysicists say that there is a clear, unambiguous signal in the cosmos which could eliminate inflation as a possibility.

Have you ever wondered what it would be like to travel to outer space – and then keep going? What would you find?

A team of Canadian astronomers have used the James Webb Telescope (JWST) to identify the most distant globular clusters ever discovered.

Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang per physicists in Canada.

Right above you is the sky – or as scientists would call it, the atmosphere. It extends about 20 miles (32 kilometers) above the Earth.

Standard cosmological models tell us that the universe – space, time and mass/energy – exploded into existence some 14 billion years ago.

UC Riverside physicist and colleague invoke the cosmological collider to explain why matter, and not antimatter, dominates the universe

Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang.

Groundbreaking observation from Gemini Observatory suggests this and possibly other colossal stars are less massive than previously thought.

Some cosmological models propose that the universe expands and contracts in infinite cycles, but new research finds a crucial flaw

A team has developed a method that will allow them to ‘see’ through the fog of the early Universe and detect light from the first stars.

Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang.

New research suggests an unseen ‘mirror world’ of particles might be the key to solving a major puzzle in cosmology – the Hubble constant.

A unique new instrument, coupled with a powerful telescope and a little help from nature, enables scientists to peer into galactic nurseries

Earth-based telescopes that look that far back to the big bang (BB) 13.8 billion years ago are unable to resolve the relevant details.

The more humanity tries to do more with data, the more it’s evident that the most urgent questions won’t get answered easily.
