For decades, scientists have worked to map the universe’s large-scale structure, testing cosmological models and investigating how galaxies form and evolve. Most studies describe these massive ...

"This is how you solve the universe-breaking problem." ...

“We [will be able to] move quickly and map out very large areas of the sky,” adds Josh Schlieder, the telescope’s wide-field ...

Mysterious little red dots threatened to overhaul modern cosmology—but new research may have solved the celestial conundrum.

so faraway stars look redder since they have a higher redshift. JWST is designed to look deep into the red and infrared spectrum, detecting old, distant galaxies better than any other telescope.

Chinese astronomers have investigated quasar candidates from the DESI Legacy Surveys (DESI-LS) photometry catalog. As a ...

Space Telescope’s Ultra Deep Field ... Red light has the longest wavelength. The so-called “redshift” measured by JWST’s NIRCam for four galaxies was 10.38, 11.58, 13.20 and 12.63 ...

Space Telescope Science Institute sent out a tweet ... The quasar shown in the image is a 17th magnitude object at redshift z = 2.133 (10.6 billion light years away).

Its mission is to cover the full range of modern astrophysics, from exoplanets to the high-redshift universe, but the road to first light was not an easy one for the binocular telescope.

The next great space telescope will study distant galaxies and faraway planets from an orbital outpost about a million miles from Earth. But first it has to be put together, piece by piece ...

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the ...
