Description
This is my interpretation of the WR 104 system, is a binary star system located about 7,500 light years from Earth. The primary is a Wolf-Rayet star and the secondary is a Main Sequence OB Star.WR 104 is surrounded by a dusty pin-wheel 'nebula' over 200 astronomical units long formed by interaction between the stellar winds of the two stars as they rotate and orbit around the centre of mass in the system.
Comments please.
No stealing.

If the case for the future of the Sun as a deadly red giant near the end of its life isn't bad enough, then the Earth will still face some disasters from outside the Solar System, mostly from this spiral full of binary stars.
Quite possibly, millions of years from now may one of these stars in this spiral explode into straight, directional beams of gamma rays; ready to strike the Earth from far away while humanity as a Type 3 civilization are still busy of colonizing the Milky Way galaxy.
If the gamma rays from WR 104 headed straight towards the Earth, then it would have reduced the ozone layer and made the Earth more exposed to the UV radiation from the Sun, thus causing deprivation of life, and mass extinctions. Some theorized a gamma ray burst had hit Earth in about 400 million years ago in the Ordovician epoch.

Indeed. The threat of the Sun entering the Red Giant phase of its life is still many years away, with the closer threat of the growing power and luminosity of the Sun being more of an issue, as Humans are forced from Earth to live on other bodies within our Sol System due to the Habitable Zone moving away from the Earth.
Yes, Binary Stars are a different animal, due to the Type 1a Supernova they produce when one member of the Binary System steals matter from its neighbour.
Gamma Ray Bursts are deadly, but they don't happen very often as most Stars don't produce them due to some not being massive enough, and the axis of the Star isn't typically pointed in our direction. If Humanity can reach a Kardashev Scale's Type II Civilisation, then they wouldn't need to worry over so much over a Gamma Ray Burst or Supernova, as they aren't confined to one planet like we are now.
Yes, I recall an episode of The Universe (TV series), talking about how they theorised that a Gamma Ray Burst struck the Earth and caused the Ordovician Extinction. As a Gamma Ray Burst would strip the Ozone Layer and create Nitrogen Dioxide, creating a blanket of smog around the Earth, further killing life due to lack of warmth, and light that aids in the Photosynthesis of plant life which some animals utilise as food.

A pretty, but deadly spiral~

Oh yes. :3
Same here, I do love that subject. :3

Ever heard of a Thorne-Zytkow object?

Yes, they are a red giant, or supergiant star, which contains a neutron star at its core. Although they're still under debate, I think, although they discovered a strong candidate last year, if I remember correctly.

You know your stuff.
I once thought about an HR diagram with an extra axis of mass.
