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 […]

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 […]

ALMA Spots a Nascent Stellar Monster

by Jason Major July 10, 2013

Even though it comprises over 99% of the mass of the Solar System (with Jupiter taking up most of the rest) our Sun is, in terms of the entire Milky Way, a fairly average star. There are lots of less massive stars than the Sun out there in the galaxy, as well as some real […]

A Mega-Merger of Massive Galaxies Caught in the Act

by Jason Major May 22, 2013

Even though the spacecraft has exhausted its supply of liquid helium coolant necessary to observe the infrared energy of the distant Universe, data collected by ESA’s Herschel space observatory are still helping unravel cosmic mysteries — such as how early elliptical galaxies grew so large so quickly, filling up with stars and then, rather suddenly, […]
