Understanding the Hubble constant and the challenges in measuring the universe's expansion rate
Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...
For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...
A difference of a few kilometers per second might not sound like much. In cosmology, it has become one of the field’s most stubborn problems. An international team of astronomers has now delivered one ...
By Will Dunham WASHINGTON, June 16 (Reuters) - Taking a fresh look at data involving a specific type of stellar explosion, a ...
Artist’s interpretation of the cosmic distance ladder — a succession of overlapping methods used to measure distances across the Universe, where each rung of the ladder provides information that can ...
A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s faster than early-Universe models predict. By linking multiple ...
Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...
Schematic of the expansion of the universe from the big bang (starting on the left side) to the present day. We have known for several decades that the universe is expanding. Scientists use multiple ...
When you bake a loaf of bread or a batch of muffins, you put the dough into a pan. As the dough bakes in the oven, it expands into the baking pan. Any chocolate chips or blueberries in the muffin ...
We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...
