This galaxy existed just 400 million years after the Big Bang and provides new insights into the first generation of galaxies. This is the first time that the distance of an object so far away has ...

How would you like to see the farthest thing visible to the naked eye? It’s possible, but you’ll need to bundle up and sit back on a lawn chair. Your neighbors may think you’ve cracked up sitting out ...

When Brant Robertson saw a new measurement of the distance to a familiar galaxy, he laughed out loud. For more than a decade, the galaxy had been a contender for the most distant ever observed. In ...

The most distant galaxy cluster yet has been discovered by combining data from NASA’s Chandra X-ray Observatory and optical and infrared telescopes. The cluster is located about 10.2 billion light ...

How old is our universe, and what is its size? A team of researchers led by University of Hawaiʻi at Mānoa astronomers Brent Tully and Ehsan Kourkchi from the Institute for Astronomy have assembled ...

Vesto Slipher first observed that galaxies are moving away from us. Edwin Hubble later showed a relationship between galaxy distance and speed. Hubble's work relied heavily on Slipher's earlier data.

Our Universe consists of hundreds of billions of galaxies, and for nearby galaxies, distances are mainly measured by classical Cepheids and RR Lyrae (RR Lyr) stars. RR Lyr stars are pulsating variable ...

(Nanowerk News) How old is our universe, and what is its size? A team of researchers led by University of Hawaiʻi at Mānoa astronomers Brent Tully and Ehsan Kourkchi from the Institute for Astronomy ...

A full-sky map showing Cosmicflows-4's 56,000 galaxies with distance measurements. Each dot represents a galaxy, and the color of the dot indicates distance from us, with blue tones nearby and redder ...

Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4. How old is our universe, and what is its size? A team of researchers led by University ...
