What's going on?
Big Bang theory is the leading explanation for how our universe began. According to the theory, the entire universe began as a tiny singularity that went through an explosive expansion 13.8 billion years ago, gradually expanding into the cosmos we see today. Today, astronomers can detect an "echo" from the Big Bang in the cosmic microwave background, a phenomenon that can be detected with radio telescopes. Big Bang Theory is also the name of a popular CBS sitcom about scientists, where several real-life scientists and astronauts have appeared.
The Nobel Prize in physics this year has gone to two very different research threads — and danced around some big societal issues, even as they celebrate distinguished work.
The Nobel Prize in physics has been awarded to three scientists for unraveling the structure and history of the universe and for changing our perspective of Earth’s place in it.
Warps in the fabric of space-time can act like magnifying glasses, and that may help solve a cosmic mystery about the rate of the universe's expansion, a new study found.
Our lives here on Earth are small and insignificant and inconsequential — but only in a certain frame of reference, and that frame of reference doesn't necessarily apply to cosmic scales.
The universe is expanding faster than expected, suggesting that astronomers may have to incorporate some new physics into their theories of how the cosmos works.
To see if there was a universe before the Big Bang and understand how the cosmos evolved after it began, researchers suggest looking for the influence of particles that acted like clocks.
Come 2023, NASA will have a new eye tracking the heavens and looking to solve some of the greatest scientific mysteries we know of.
What does a star feel like? A team of scientists put astronomy on a vibrating sound stage in order to tackle such questions.
The Hubble Space Telescope has discovered a dwarf galaxy in our own cosmic backyard, a mere 30 million light-years from the Milky Way.
We now have a better idea of how big black holes were born in the early universe, a new study reports.
Back in the first moment of the universe, everything was hot and dense and in perfect balance. A new quantum experiment aims to show how that changed.
