To determine the Hubble constant, scientists rely on a “cosmic ladder” of measurement methods, each building on the last to estimate distances to far-off celestial objects. The ladder starts with ...

The findings lend new weight to the longstanding cosmological quarrel involving what astronomers call the “Hubble tension,” challenging our ... Scolnic and his team employed the use of a “cosmic ...

"The DESI collaboration did the really hard part, their ladder was missing the first rung," said Scolnic. "I knew how to get it, and I knew that that would give us one of the most precise measurements ...

Using this high-precision measurement as a first rung, the team calibrated the rest of the cosmic distance ladder. They arrived at a value for the Hubble constant of 76.5 kilometers per second per ...

The Hubble Space Telescope, for comparison, has a 6.5-foot (2 m) aperture, he said. Breaking space news, the latest updates on rocket launches, skywatching events and more! Even the smallest ...

Yet, a century ago, its discovery by Edwin Hubble, then an astronomer at Carnegie ... rung of what astronomers call the "cosmic distance ladder" needed to build a yardstick to far-flung galaxies.

Hubble captured an exploding star about 650 million light-years from Earth. The Hubble Space Telescope recently captured a snapshot of a rare supernova that sits in the Gemini constellation, about ...
