The latest measurements with the Hubble Space Telescope suggest the universe is expanding faster than scientists' models predict—a hint that some unknown ingredient could be at work in the cosmos.
Well, the way we are able to see something is via light. And although the speed of light is the fastest way to travel through the universe, it needs time to get from one place to another. Every second light reaches us from trillions of galaxies that have passed the horizon because when...
In 1998, scientists used NASA's Hubble Space Telescope to determine that the universe is expanding faster each year — an unexpected result. They concluded that a source of energy, dubbed "dark energy" because it remains unseen, is responsible for the push. The elusive energy makes up about ...
(C)The universe is getting bigger every second. The space between galaxies is stretching, like dough rising in the oven. But how fast is the universe expanding? As Hubble and other telescopes seek to answer this question, they have run into an intriguing difference between what scientists predi...

the universe has been expanding, we know that the most faraway things whose light we can see are actually 45 billion light years from us right now. So the observable universe is a sphere with a radius of 45 billion light...
Astronomers have pegged the universe's current expansion rate — a value known as the Hubble constant, after American astronomer Edwin Hubble— at about 44.7 miles (71.9 kilometers) per second per megaparsec. (One megaparsec is about 3.26 million light-years.) This newly derived number is ...
For example, inJune of 2016, NASA announced findings that indicate that the Universe is expanding even faster than previously thought. Based on new data provided by the Hubble Space Telescope (which was then compared to data from the WMAP and the Planck Observatory) it appeared that the Hubble...
The speed at which the universe is expanding is known as the Hubble constant, and it’s a key piece of the puzzle for understanding how the universe has changed over time and what its future might look like. But there’s a long-standing mystery called the "Hubble Tension." ...
