Probing the Surroundings of Tycho’s Supernova
A supernova that Tycho Brahe studied in 1572 may yet have something to tell us about what causes supernovae.
The speeding binary that shouldn’t exist
A mysterious pair of stars speeding through the outskirts of our galaxy together puzzles astronomers
Have we been hit by a supernova?
Today’s paper describes models of what a nearby supernova would do to a young planetary system, and looks at whether the same may have happened to our own solar system.
Supernova Archeology with Radioactive Eyes
Today’s bite looks at how the ratio of various elements can inform our view of what happens during a supernova.
Sensing a Pulsar’s Sense of Rotation
It should be easy to figure out which way a pulsar is spinning, right? Wrong.
Exploding stars and sleight of hand: A case of magnetic misdirection
Supernova remnant magnetic fields may play a key role in accelerating electrons to relativistic velocities. West et al. investigate the magnetic field conditions inside young supernova remnants and discover that they may not be as well-behaved as they appear.
