On the road: AAS January 2013 meeting — supernovae and dark energy
Liz Kruesi
It’s the end of the third full day, and my last, at the American Astronomical Society meeting. In addition to attending press conferences about exploding massive stars and cosmology, I spent time checking out some of the poster presentations and attending science sessions about imaging exoplanets...

On the road: AAS January 2013 meeting — more exoplanets and a donated telescope
Liz Kruesi
As the second full day of the American Astronomical Society (AAS) meeting comes to an end, exoplanets yet again were a major focus. The first press conference of the day included announcements of surprising planetary systems. First, we learned of evidence of a planetary system in the Hyades star cluster...

Higgs boson NOT discovered (yet)
Bill Andrews
Last week, scientists at the European Organization for Nuclear Research (CERN) announced findings related to their search for the Higgs boson , a long-sought elementary particle. In fact, it’s the only elementary particle predicted in the standard model — the current set of theories physicists...

On the road: The Antarctic Science Symposium, April 27, 2011
Liz Kruesi
The Antarctic Science Symposium in Madison, Wisconsin, started off with a few presentations about drilling technology. It’s definitely an important topic because one of the reasons scientists utilize Antarctica as a lab is the ice — either used as a detection material, or a record of climate...

Astronomy in Antarctica
Liz Kruesi
In December 2010, the IceCube collaboration placed its last string of detectors 1.5 miles (2.5 kilometers) into the Ataractic ice. This project consists of 86 strings, for a total of 5,160 detectors embedded in 0.4 square mile (1 square km) of ice. The IceCube project is searching for neutrinos —...

A ridiculously basic problem on the set of "Cosmic Adventures"
Liz Kruesi
Ever wonder what goes on behind the scenes of “Liz and Bill’s Cosmic Adventures”? We just debuted Episode 4 , and reviewing the final draft of the video reminded me how much of a pain it was to film one of the scenes. (Spoiler alert if you haven't yet watched it!) Bill and I...

Road trip: Fermi National Accelerator Laboratory, part 2
Rich Talcott
When you hear the name Fermi National Accelerator Laboratory, or Fermilab for short, cosmology likely isn’t the first thing to cross your mind. But Fermilab researchers are busy building an astronomical camera that could help confirm that dark energy rules the current universe — or the unsettling...

Road trip: Fermi National Accelerator Laboratory
Liz Kruesi
The Fermi National Accelerator Laboratory in Batavia, Illinois, invited press and amateur astronomers to visit on November 17 and view a camera it’s building for a dark-energy study. Senior Editor Rich Talcott and I jumped at the chance to see the lab. Fermilab is about 2.5 hours south of Astronomy...

New video: Dark matter explained
Liz Kruesi
In my newest video, I give you an overview of dark matter , that mysterious stuff that makes up some 90 percent of the universe’s mass. During the last few decades, astronomers have gained convincing evidence that stars, gas, and dust aren’t all there is to the universe. Most of it is “dark” — both dark...

Relativity rap
Liz Kruesi
It’s great how some people communicate science ideas. A few months ago we heard about the science writer at the Large Hadron Collider who filmed a rap video about the LHC and posted it on YouTube. So what does this have to do with Astronomy ? Well, Rob Wheeldon, a reader and fellow astronomy enthusiast...

Are you good with statistics and interested in cosmology? Well, astronomers have issued a challenge to aid in the understanding of dark matter and dark energy — the mysterious stuff that makes up roughly 95 percent of our universe. Thirty-eight astronomers from 19 international institutions are issuing...

Why I love cosmology

Yesterday I spent a bit of time reading through the scientific paper regarding the flow of galaxy clusters pulled by possible dark matter beyond the universe’s horizon. I don’t know what it is about cosmology, but I find it fascinating. It’s weird stuff, completely crazy ideas, and very difficult to...
