Sagittarius Wants to Kill You

One of the reasons why Ive had a hard time completely rejecting astrology is the fact that Im such a stereotypical Sagittarius: the optimistic, free-spirited (clumsy, arrogant, slutty) philosopher. The Archer is a friendly constellation, flanked by stinging Scorpio, the cosmic douchebag, and Capricorn, which is some sort of bizarre goat-fish abomination. Screw those guys. The wise centaur Chiron whom Sagittarius represents smiles upon mankind, offering the blessings of knowledge, and through Sagittarius lies the center of the Milky Way, which Im sure is symbolic of something. In a nutshell (terrible joke), I am down with the Archer.
Imagine my dismay when I learned that deep in my natal constellation whirls Wolf-Rayet 104, a binary star system in the final stages prior to supernova. This so-called Death Star was discovered by University of Sydney astronomer Peter Tuthill, who so delightfully informs us that, upon supernova, It could emit an intense beam of gamma rays coming our way. The beautiful spiral images that we have of WR104 are the result of our pole-on view of the star system; when it goes into supernova, it looks awfully possible that the gamma ray burst its bound to emit is pointed in our direction. Totally sweet.
Now, if youre like me, you only know a few things about gamma rays: that they make you quite irritable and that they cause some sort of an irrepressible need to wear purple shorts. Terrified at the consequences for my wardrobe, I investigated further:
In the worst-case scenario of an aligned GRB, what then?
Consequences are mainly related to global impacts on the biosphere and climate-change triggered by the large dose of radiation.
The good news is that we are not all *that* close to WR 104. For a fully-fledged GRB, we may be within the dangerous range but it is by no means a point-blank shot. If SN/GRBs form a continuum of events ranging from highly directed gamma beams through to slightly egg-shaped supernovae, then this means that we are safe from all but the more extreme focussed beam events. To carry a lot of clout over larger distances, a smaller cone angle is needed, tilting the odds and making it increasingly less likely that Earth is in the beam.
From the WR104 Technical FAQ.
So, according to Dr. Tuthill, if were in firing range, were headed for mass extinction. But its not certain (and it may happen a few thousand years from now), so yall can (probably) rest easy.
Or not.
Because at the heart of Sagittarius also lies the closest black hole to Earth, merely 1,600 light years away. Not content with just one, Sagittarius also houses another black hole, Sagittarius A*, the closest supermassive black hole to Earth, conveniently located at the galactic center. Both offer us invaluable information about the activities of black holes due to their proximity. Because, you know, black holes are definitely the outer space phenomenon that we want to be close to. Awesome.
So, basically Sagittarius wants to shoot us with cancer rays, and if we get near it, well get eaten by a black hole.
Why is Sagittarius such a fucking asshole?
So here I type, disenchanted with the Archer whom I once gazed upon happily, probably stoned, with a bunch of astronomer friends from Portland in my seemingly distant youth. Now I look cynically upon the stars, knowing that the constellation for which I once held such affection just wants to kill me.
But the Universe is just and poetic. The closest galaxy to our own is the Sagittarius Dwarf Galaxy, discovered in 1994. It is slowly being torn apart by the gravitational forces of the Milky Way.
So, to that I say:
MILKY WAY #1! MIL-KY WAY! MIL-KY WAY! WOOOOOOOO!
Flux knows that the black holes in Sagittarius dont really pose much of a threat to us, but she still thinks that Sagittarius is a total dick. Which, come to think of it, only makes it an even more appropriate zodiac sign for your intrepid correspondent.
