Some days ago, Freija Descamps, one of the “winter-overs” taking care of IceCube during the months-long South Pole night, sent to us in the North this great picture of the aurora australis, and I wanted to share it with you.
Serving as a background to the aurora is the pale glow of the Milky Way in the region of Sagittarius, with Scorpius hanging on top of it. Behind the curtain of stars, gas, and dust of the Sagittarius region sits the center of our home galaxy, a candidate source of neutrinos and energetic cosmic rays.
Thanks for sharing this. It’s absolutely wonderful.
Great to hear news about Freija! =)
I was in the same physics class as her, back in 2004–2005…
