Teamwork! Two Telescopes Combine Forces To Spot Distant Galaxy Clusters

by Elizabeth Howell February 12, 2014

Doing something extraordinary often requires teamwork for humans, and the same can be said for telescopes. Witness the success of the Herschel and Planck observatories, whose data was combined in such a way to spot four galaxy clusters 10 billion years away — an era when the universe was just getting started. Now that they […]

How Massive Is A Neutrino? Cosmology Experiment Gives A Clue

by Elizabeth Howell February 10, 2014

There have been a lot of attempts over the years to figure out the mass of a neutrino (a type of elementary particle). A new analysis not only comes up with a number, but also combines that with a new understanding of the universe’s evolution. The research team investigated the mass further after observing galaxy […]

This Very Old Cosmic Light Has A Bend To It

by Elizabeth Howell October 1, 2013

Leftover radiation from the Big Bang — that expansion that kick-started the universe — can be bent by huge cosmic structures, just like other light that we see in the universe. While the finding seems esoteric at first glance, scientists say the discovery could pave the way for finding a similar kind of signal that […]

Watch Live Webcast: Oldest Light in the Universe from Planck

by Nancy Atkinson July 31, 2013

Earlier this year, a new map of the Cosmic Microwave Background from the Planck spacecraft revealed our Universe was a bit older and is expanding a tad more slowly that previously thought. Additionally, there are certain large scale features that cosmologists cannot readily explain. In fact, because of this finding — possible because of the […]

Meet Hopper: A Key Player in the Planck Discovery Story

by David Dickinson March 22, 2013

Behind every modern tale of cosmological discovery is the supercomputer that made it possible. Such was the case with the announcement yesterday from the European Space Agencies’ Planck mission team which raised the age estimate for the universe to 13.82 billion years and tweaked the parameters for the amounts dark matter, dark energy and plain old […]
