NASA's Hubble Space Telescope explores the evolution of spiral galaxy UGC 10043 through images taken 23 years apart, in 2000 ...

A pair of quasars that existed when the universe was only 3 billion years old has been spotted by the Hubble Space Telescope.

Hubble’s updated view of NGC 3370, richer in light and detail than ever before, deepens our understanding of both the galaxy and the cosmos itself. This new Hubble Picture of the Week highlights a ...

The Hubble tension is one of the biggest mysteries in cosmology. It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different numbers ...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 million ...

Our universe appears to be expanding about eight percent faster than initially assumed possible, according to new observations from the James Webb Space Telescope. There has been a long-established ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the cosmos.

On the night of Oct. 5 to 6, 1923, Edwin Hubble discovered a new star — and revealed the utter vastness of the universe. Hubble was looking at the cosmos with the 100-inch Hooker telescope at the ...

The two keys to Edwin Hubble's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to calculate ...

The universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous—and highly debated—results had shown: The universe is expanding faster than predicted by ...
