The scientists realized that these supernovae weren’t as nearby as they had thought, so they had zipped away from Earth quicker than expected. “These observations led scientists to ultimately conclude ...

Everything started with the Big Bang. Most astrophysicists agree that the force generated by the Big Bang continues to push stars, planets, and galaxies apart from each other as our universe expands.

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

It is widely thought that our universe is expanding at an ever-accelerating rate. But could we have that wrong? That is what a group of scientists from South Korea claims, but other scientists have ...

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...

The latest wave of cosmology results suggests the universe might not be the smooth, predictable machine textbooks once ...

The universe has likely shifted from a period of acceleration to a phase of deceleration, new study by Korean researchers ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

Dark energy is by far one of the most intriguing aspects of the cosmos that scientists are still trying to fully decode. While we're pretty sure that the universe is held together by the mysterious ...
