Parece que no somos alienígenas

Pues eso, es curiosa la noticia que se ha propagado, donde se especulaba con la posibilidad de que en realidad nuestro Sistema Solar no pertenece a la Vía Láctea, sino a la galaxia enana Sagitario, que está siendo engullida por la propia Vía Láctea. En concreto, se puede leer en

o en
http://www.20minutos.es/noticia/253275/0/galaxia/sagitario/tierra/

En la misma se cita a Steven R. Majewski como responsable de esta "noticia". Hasta el punto que en la página de este investigador (http://www.astro.virginia.edu/~srm4n/), el mismo escribe:

IF YOU ARE LOOKING AT THIS WEBPAGE BECAUSE YOU WANT TO CONTACT ME REGARDING FALLACIOUS NEWS REPORTS ABOUT THE SUN BEING FROM THE SAGITTARIUS DWARF GALAXY:

1. DO NOT BELIEVE EVERYTHING YOU READ ON THE INTERNET! WE HAVE NEVER MADE THE CLAIM THAT THE SOLAR SYSTEM IS FROM THE SAGITTARIUS GALAXY, AND REPORTS TO THE CONTRARY ARE A GROSS DISTORTION OF OUR RESEARCH!

2. IF YOU ARE A JOURNALIST, PLEASE FOLLOW TRADITIONAL JOURNALISTIC STANDARDS AND DO PROPER SOURCE AND FACT CHECKING! (IF OTHER SUPPOSEDLY RELIABLE NEWS AGENCIES HAD SUBSCRIBED TO THESE BASIC PRINCIPLES, YOU PROBABLY WOULD NOT BE WASTING TIME RIGHT NOW CHASING DOWN THIS ILLEGITIMATE NEWS STORY!)

3. THE WEBSITE http://www.badastronomy.com/bablog/2007/06/27/is-the-sun-from-another-galaxy , WRITTEN BY A Ph.D. ASTRONOMER, DOES A REASONABLE JOB OF ADDRESSING THE MISINFORMATION BEING CIRCULATED AROUND THE WORLD IN THIS "NEWS STORY" HOAX.

4. If after reading the above referenced wesbite you still wish to ask questions either about the ACTUAL science involved in our research, or my opinions about how shoddy reporting (at least reporting of science) has become in the mainstream press, please feel free to send me an email.

PS: It is ironic that journalists, who constantly rail against blogs as illegitimate sources of news, elected here to rely on a blog from someone with no scientific credentials (but a lot of imagination) as the sole source for breaking fanciful, but completely incorrect stories on something purporting to be as important as "one of the most pivotal discoveries of our time"....

También se refuta esa "noticia" aquí.

Bueno, lo que sí que no tiene desperdicio y está totalmente contrastado es el canibalismo galáctico que se está produciendo entre la Vía Láctea (la depredadora) y la galaxia enana Sagitario (la pobre presa). La noticia fue divulgada en 2001 por el Instituto de Astrofísica de Canarias, y es espectacular. Podéis consultarla en:
