A new assessment of the Cosmic Microwave Background shows that the oldest stars ignited 150 million years later than previously thought. It's a realization that's forcing cosmologists to rethink the 13.8 billion year history of the Universe.
The swirls, loops and arches in this image may look like a new artwork—but they are in fact the results of the first ever all-sky observations of polarized light emitted by interstellar dust in the Milky Way, and they represent the galaxy's magnetic fingerprint.
From slow-mo footage on YouTube to deep-space satellite imagery to weird washcloths on the International Space Station, this was a big year for beautiful science. Here for your visceral viewing pleasure are thirty-three of our favorite photos and videos from 2013.
This week, the Planck Satellite team announced major findings from over a year of observations of the Cosmic Microwave Background (CMB), or the radioactive sludge that lingers in our universe from the beginning of time, right after the Big Bang. And while there's a lot to digest, I wanted to give you some high points…
I can't get over how fantastic this image is. It was originally captured in 1927 at the fifth Solvay Conference, one of the most star-studded meetings of scientific minds in history. Notable attendees included Albert Einstein, Niels Bohr, Marie Curie, Erwin Schrödinger, Werner Heisenberg, Wolfgang Pauli, Paul Dirac…
Back in late 2010, astrophysicists spotted two gargantuan, gamma-ray emitting bubbles mysteriously coming out of the galactic center. Now the bubbles have an equally baffling companion: a strange haze of microwaves that extends through the galaxy, and "defies explanation."
