The HAWC Collaboration has made the first detailed measurements of two pulsars touted as possible sources of the positron excess observed in 2008 by the spaceborne detector AMS-02. By catching and counting particles of light streaming forth from these nearby stellar engines, reserachers have showed that these two pulsars are very unlikely to be the origin of the excess. The results are published today in Science.
Flight canceled? Well, that happens. But, canceled … again? Welcome to plane travel at the Pole. The changeable weather patterns in the harsh climate of Antarctica make flights in and out susceptible to delays. It’s part and parcel of the whole experience.
Lots of firsts as a new summer season begins at the South Pole. Last week saw the first LC-30 to arrive, seen here as it’s being marshaled in and later after landing and releasing a group of red parkas onto the ice, the first group of many to come. The changing-of-the-guard period at the Pole has begun.
Shoveling snow might not be that much fun, but at least at the South Pole, afterward you can walk away with a pretty “epic” beard, as the winterovers recently put it. Well, if you have a beard to begin with, that is.
IceCube is proud and excited to be a part of the Wisconsin Science Festival this year. The Discovery Expo will take place at the Discovery Building and will begin on Thursday, November 2nd.
After a long, cold winter at the South Pole, it might be hard to decide which is more exciting: the first plane of the season or its contents. Apparently, people get pretty excited at the sight of a bowl of tangerines after going without any fresh fruit for eight or nine months.
