We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have ...

Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It was believed that ...

In a new Physical Review Letters (PRL) study, scientists explore the possibility of nontrivial or exotic topologies in the universe for explaining some of the anomalies seen in Cosmic Microwave Background (CMB).
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure ...

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to measure the universe's origin and evolution ...
