Barnard 68

Barnard 68

Where did all the stars go? What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud. Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help make the interiors of molecular clouds some of the coldest and most isolated places in the universe. One of the most notable of these dark absorption nebulae is a cloud toward the constellation Ophiuchus known as Barnard 68, pictured above. That no stars are visible in the center indicates that Barnard 68 is relatively nearby, with measurements placing it about 500 light-years away and half a light-year across. It is not known exactly how molecular clouds like Barnard 68 form, but it is known that these clouds are themselves likely places for new stars to form.

Canción del día (290)

Escribo ésto con la esperanza puesta en ese piso tan cuco que hemos encontrado, en alegrarte al ver que me preocupo por ti y en este fin de semana, colofón de una semana agotadora, con mucho, mucho ajetreo.

Mañana nuevas visitas, concierto, bocatas y abrazos. No puedo pensar en nada más que en el deseo de que sea mañana…
