James Webb Space Telescope maps our universe's largest structure in unprecedented detail

By Robert Lea published 7 hours ago

"JWST has completely changed our view of the universe."

 

The large-scale structure delivered by COSMOS-Web provides a wealth of information greater than that provided by earlier maps of the same region of sky captured by the Hubble Space Telescope. Team member and UCR scientist Bahram Mobasher explained that comparing Hubble and JWST shows that many cosmic structures had been "smoothed over" in data from the JWST's space telescope predecessor.

 

"The jump in depth and resolution is truly significant, and we can now see the cosmic web at a time when the universe was only a few hundred million years old, an era that was essentially out of reach before JWST," Mobasher said. "What used to look like a single structure now resolves into many, and details that were smoothed away before are now clearly visible."

 

The impressive leap in detail provided by the JWST and COSMOS-Web is the result of the unification of two of this powerful new space telescope's key strengths.

 

"The telescope detects many more faint galaxies in the same patch of sky, and the distances to those galaxies are measured far more precisely," Hatamnia said. "Each galaxy can therefore be placed into the correct slice of cosmic time, sharpening the map's resolution."

 

The team's research was published on May 6 in The Astrophysical Journal.

Pic Description:

A slice through the COSMOS-Web cosmic-web map, showing galaxies across nearly 14 billion years of cosmic history. The vertex on the left marks the present day; moving outward, each galaxy is placed at its distance in cosmic time, reaching back to when the universe was less than a billion years old. Bright yellow regions show the dense clusters and filaments of the cosmic web, while dark regions mark the near-empty voids in between.

Remember the NASA space project Voyager (VGER for Star Trek fans) launched 49 years ago and still going?
 

Problem isn’t so much the craft, but the fact that the original personnel are all gone and the vastly inferior computing at that time.
