NASA: Our SOLAR SYSTEM has a friggin’ TAIL.
I say goddamn! Now our solar system is yet another entity I’m in love with that has a tail. Them fucking tails are so seductive. Like, great for balancing. And sticking into input units and shit. Wait — it isn’t a literal tail?
Our solar system, home to Earth and the other seven planets, may be the equivalent of our own backyard in astronomical terms, but it’s still full of surprises. The latest, according to NASA, is that the entire solar system has a humongous tail, estimated to be a cool 93 billion miles long (1,000 times further than the distance from the Earth to the Sun). Called the “heliotail,” the structure is made up of solar wind, or particles originally released by the Sun, some of which travel billions of miles past all the planets and escape the magnetic field surrounding the solar system. The particles are invisible to the naked eye by the time they reach the edge of the field. Nonetheless, scientists had long suspected that our solar system had such a tail based on telescopic observations of similar tails trailing other star systems, but our heliotail had never been accurately detected — until now.
Credit for the reveal goes to NASA’s Interstellar Boundary Explorer (IBEX) mission, an unmanned particle-detecting spacecraft launched in 2008 and which remains in orbit around the Earth. “We did not have any data prior to IBEX to tell us if a tail existed, what it looked like, or how various particles behaved within that region,” noted Dave McComas, IBEX’s principal investigator, in a blog post today. But after three-years-worth of observations, the mission finally compiled enough data on neutral particles streaming back into the solar system from the tail, for scientists to be able to identify it and map its structure.

None the less, pretty rad ass. Makes me think of circles within circles. We’re rocketing through space on Earth. We’re rocketing through space in our solar system. We’re rocketing through space as the Milky Way Galaxy. #InceptionHorn or something.
