Astronomers have discovered auroras around a set of brown dwarfs — including one that wanders the galaxy by itself — indicating surprisingly strong magnetic fields in these failed stars.
This week in astronomy: Simulations show what kind of cataclysmic impact shaped the ice giant Uranus's evolution, new observations from Juno reveal complex auroral patterns due to Jupiter's moons, and NuSTAR provides conclusive evidence that the superstar Eta Carinae acts as a cosmic-ray accelerator.
Hubble reveals a relic galaxy, Dawn sees the surface of asteroid Ceres changing, and scientists probe an auroral phenomenon named "Steve."

The Aurora Borealis is one of those magical items on everyone’s bucket list. Here at Gordon’s Park we are fortunate to be far enough north and far enough from a major city to be able to view the Aurora Borealis from our Dark Sky Preserve throughout the year, with the best viewing times being in…
The story of Steve, the mysterious pink-ribbon aurora, shows how citizen scientists are making important contributions to research and discovery.
