Not-So-Clumpy Dark Matter Poses Cosmological Challenge
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.
The Kavli Foundation Q&A: What Has Planck Taught Us About the Early Universe?
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.
Planck Upholds Standard Cosmology
The Planck team has finally released its full-mission data, revealing a remarkably detailed view of our universe and our galaxy.
Dust Makes Cosmic Inflation Signal Iffy
A new analysis of Planck data bolsters the claim that the polarization signal heralded as evidence for cosmic inflation is from dust instead.
Big Bang Inflation Evidence Inconclusive
New analyses suggest that observations heralded as evidence for the universe’s brief growth spurt don’t conclusively show what researchers thought they did.
Planck's Magnetic Map of Our Galaxy
The ESA's Planck mission has released one of the most detailed maps of the Milky Way's magnetic field.
Planck Spacecraft Shut Down
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.
Planck: Best Map Yet of Cosmic Creation
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.
