For the first time, an international collaboration of scientists has detected extremely high-energy gamma rays, the most powerful type of light, coming from the outermost regions of an unusual star system within our own galaxy. The source is microquasar SS 433, a black hole that gobbles up stuff from a nearby companion star and blasts out powerful jets of material. The team’s observations, described in the October 4 issue of the journal Nature, represent the most energetic radiation ever detected from a microquasar in our galaxy.

And then there were four.  Last week saw the arrival of IceCube’s two new winterovers, Kathrin and Benjamin, joining departing winterovers Raffaela and Johannes before they leave the Pole.  On their first visit to the ICL, they set up a camera timer to capture a group photo.  But the timer was a bit fast for getting back into their planned arrangement atop a giant snowdrift—so, antics ensued.

IceCube was quiet and well behaved last week, but the week was full of all sorts of other activity now that the summer season is officially underway.  Here we see IceCube winterover Raffaela getting ready to help park the first passenger aircraft of the season.

Ok, so you’ve completed that giant 18,000-piece jigsaw puzzle, now what? Well, you might not want to take it apart again, at least not for a while. The folks at the South Pole decided to give theirs a place of honor on the wall in the B2 science lab.

In a new measurement published recently in The Astrophysical Journal, HAWC has looked deeper into the region between 2 and 73 TeV and has also studied the large-scale anisotropy and the energy dependence between both the small- and large-scale features.

Bad weather at the Pole last week kept the first flights from arriving, but it also meant lots of snow shoveling and fuel line testing to continue their readiness for incoming flights once conditions do improve.
