With the sun out, you can see again—and here we see all the flags surrounding the marker at the ceremonial pole. They didn’t just appear out of the darkness, though. They were recently replaced for the summer season after being taken down for the winter. […]
Flags serve an important purpose at the Pole, marking out routes between places for when visibility is poor. Here you can see the IceCube Lab (ICL) in focus behind a flag line in the foreground. […]
The IceCube Collaboration fall 2016 meeting ends today at Johannes Gutenberg Universität Mainz in Germany. Professors Sebastian Böser and Lutz Köpke hosted the weeklong meeting.
“It’s been a total thrill to see how fast we as a collaboration are moving forward on so many fronts in parallel,” says Sebastian Böser. “I hope everyone has enjoyed the meeting in Mainz as much as we’ve enjoyed hosting the collaboration.” […]
Up, up, and away. That’s a NOAA balloon launch shown in a time-lapse photo—pretty nice! Last week at the Pole was all about the camera. […]
A new temperature record for 2016 was set at the Pole last week—a low of –107.9 °F. The extremely cold temperatures didn’t stop one station inhabitant from climbing the outdoor staircase is short sleeves. […]
The IceCube Collaboration has just announced the results of a search for point-like sources using track-like neutrino candidates detected by IceCube over seven years, from 2008 to 2015. No source has been identified, but the sensitivity keeps improving at a fast pace and will allow IceCube to test accurate models that suggest that sources could soon be observed. These results have just been submitted to The Astrophysical Journal. […]
One unique aspect of living at the Pole for a year is experiencing only one sunset, at the equinox in March, and only one sunrise, which occurs in September, while you’re there. Since the sun rises just once during the whole year, it’s kind of a big deal. It’s also a slow process, with daylight increasing little by little as the sun’s arrival nears. […]
Despite the encroaching twilight, this photo of a Scott tent near the South Pole marker also captured some faint auroras. Auroras have been caught in many shapes and forms, conjuring up cinnamon rolls and question marks, but in this case, it’s a grumpy face. At least, once it has been suggested, it’s difficult not to see it. […]
The IceCube Collaboration has expanded dark matter studies with a search for annihilations in the center of the Earth. Researchers have used one year of data—May 2011 to May 2012—and have not found an excess of neutrinos above the expected background. The results have set new limits on the annihilation rate of WIMPs in the Earth that are an order of magnitude stronger than previous results by AMANDA and that also improve the IceCube spin-independent cross section limits for a WIMP mass of 50 GeV. This study has just been submitted to The European Physical Journal C. […]
A full moon is doing just as good a job as the sun in lighting up the sky. Here the moon, surrounded by a clear halo, is shown hiding behind one of the frosty towers of the ICL. A large snow drift looms in the foreground. […]
