New analyses suggest that observations heralded as evidence for the universe’s brief growth spurt don’t conclusively show what researchers thought they did.
A new analysis of Planck data bolsters the claim that the polarization signal heralded as evidence for cosmic inflation is from dust instead.
Astronomers analyzing a new sky survey have found that the distribution of dark matter in the modern universe is smoother than predicted from observations of a far younger universe.
After four years of exquisite observations, the latest mission to study the universe's earliest light has been shuttered. But this end is a happy one and comes with a significant cosmological legacy.
The Planck team has finally released its full-mission data, revealing a remarkably detailed view of our universe and our galaxy.
The ESA's Planck mission has released one of the most detailed maps of the Milky Way's magnetic field.
Planck mission scientists have released the first half of their observations of the cosmic microwave background. The results are a stunning confirmation of today's standard model for how the universe formed and grew. But they also raise some head-scratchers.
Scientist George Efstathiou weighs in on the latest results from the Planck satellite and what they say about cosmic inflation, the first stars, and more.
