WR-104 is 2 Wolf Rayet stars in a very tight orbit 8000 light years away, normally that would be far too distant to cause the Earth any trouble but there are indications that when it goes supernovae (or more likely hyper-nova) it may produce a highly directional gamma Ray Burst, and if it does we know from examining the orbits of the 2 stars that the Earth would be very close to the center of the beam, and although the burst would only last a few seconds it could cause a lot of damage. Some think something similar happened during the Ordovician–Silurian mass extinction 440 million years ago and have started calling WR-104 The Deathstar.
