Rare ‘Pinwheel’ Stars Are a Beautiful Astronomical Puzzle

“We could see it go supernova anywhere from tomorrow to 500,000 years from now,” astronomer Grant Hill told Forbes.Melott estimates that if WR 104 were to hit us with a burst 10 seconds or so long, its gamma rays could deplete about 25 percent of the world’s ozone layer, which protects us from damaging ultraviolet rays.WR 104 is a binary star system located about 7,500 light years from Earth, surrounded by a distinctive pinwheel nebula. Gamma-ray bursts (GRBs) are short-lived bursts of gamma-ray light, the most energetic form of light. The brighter of the two stars might, just maybe kinda possibly, be ready to go GRB on us.

WR 104 is about 5,200-7,500 light years away, which is not far enough to be safe. Energy from the explosion is beamed into two narrow, oppositely-directed jets. Photo: ESO/Callingham et al.

How likely and severe is the threat of a gamma ray burst to earth?

Recent theory suggests that some gamma-ray bursts (GRB's) are core-collapse supernovae viewed nearly pole-on.

Gamma-Ray Burst

I lampi gamma, abbreviati GRB dalla locuzione inglese gamma ray burst (esplosione di raggi gamma), sono, in astronomia, un fenomeno transiente rappresentato da intensi lampi di raggi gamma la cui durata è estremamente varia: da pochi millisecondi a diverse decine di minuti e perfino ore (GRB 11209A).Our best present guess is that a full-fledged Gamma-Ray Burst from WR 104 is unlikely, although just how much energy might be beamed our way when it does go supernova is . Within the next few hundred thousand years, the system has a small probability of firing a gamma-ray burst in the general direction of the Earth.Composed mostly of high-energy gamma rays, they can carry more energy in them than the Sun will put out in its entire lifetime.Balises :WR StarWr 104 Gamma Ray BurstWolf-Rayet StarGRBArtist's illustration of a bright gamma-ray burst occurring in a star-forming region.But astronomers say the only way WR 104 could appear as an almost perfect spiral is if those of us on Earth were looking down the spin-axis of the system.

This is problematic since gamma ray bursts appear to be shot straight from the axes or poles of an object, which appears to put us straight in the firing line of the WR 104 system.Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion .
