The discovery of primordial gravitational waves through cosmic microwave background (CMB) polarization B-modes remains one of the most significant objectives in cosmology, as it would provide the ...

We can now measure the CMB—our single greatest piece of evidence about cosmic history—with a precision unimaginable at the turn of the millennium. We have mapped the distribution of galaxies ...

Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this ...

These redshifts were then used to measure distances, and allowed cosmologists to map the three-dimensional structure of the universe. One cosmic puzzle ... from the smooth CMB, as it would tell ...

Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create. In the mountains of Uzbekistan, a research ...

Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create. These stunning 3D observations may help scientists ...

These redshifts were then used to measure distances, and allowed cosmologists to map ... cosmic discovery around the turn of the century. Surveys like SDSS, combined with new observations of the ...

"This is just 1% of the map, and yet it is full of a variety of sources that will help scientists discover new ways to describe the universe." The Euclid Space Telescope has revealed the "first ...

These redshifts were then used to measure distances, and allowed cosmologists to map the three-dimensional structure of the universe. One cosmic puzzle in the 1980s ... It was important to know how ...

These objects are thought to be a source of galactic cosmic rays, the origins of which are currently a mystery. Understanding how this microquasar works could also help researchers learn more ...
