WUWM astronomy contributor Jean Creighton discusses cosmology ahead of "Birth of the Universe" at UWM's Manfred Olson ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

About 13.8 billion years ago, within a millionth of a second after the Big Bang, the universe existed in an ultra-hot and dense state. Instead of protons and neutrons, the fundamental building blocks ...

Discover why astronomy and cosmology are the universe's mapmakers. Discover how scientists trace galaxies, the cosmic web, and the large-scale architecture of our entire existence in three dimensions ...

New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For decades, scientists have held that the universe is about 13.8 billion years old ...

No matter how much order nor how many distinctions we make about the universe, in essence, it’s just a soup of subatomic waves and particles. Whether this represents some sort of primordial order or ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and ...

Scientists are starting to notice something unsettling: parts of the universe aren’t behaving the way the “trusted” rules say they should. In this video, the strangest new observations get unpacked — ...
