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 ...

This week, see how new telescopes may reshape how astronomers view the cosmos, discover forgotten medieval cities, learn ...

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 ...

NASA's SPHEREx mission won't be the first space telescope to observe hundreds of millions of stars and galaxies when it ...
