"We have discovered a galaxy that has been 'perfectly preserved' for billions of years, a true archaeological find that tells ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

Hints of the very first stars to light the Universe might be discovered in a faint radio signal feebly beaming from the dawn of time. The cosmological 21-centimeter signal emitted by the neutral ...

The figures illustrate the revealed sequential disk formation in this study: thick disk only galaxies dominate the early epochs (bottom panel), while galaxies exhibiting both thin and thick disks ...

New simulations reproduce high-redshift galaxies seen by JWST and propose a radical cosmological shift beyond ΛCDM. To simulate the universe with ...

Guided by fast radio bursts, astronomers at the Center for Astrophysics have mapped how ordinary matter is distributed in the ...

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that ...

A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already ...

Scientists have discovered the farthest-ever 'mini-halo,' a sea of charged particles around a distant galaxy cluster that ...

Such a mini-halo consists of highly energetic charged particles in the vacuum between galaxies in a cluster, which together emanate radio waves which we can detect from Earth. The discovery shows that ...

A cloud of high-energy particles surrounding a distant galaxy cluster offers a rare glimpse into the forces shaping the early ...
