Más allá del infinito

This image, taken with the Wide Field Planetary Camera 2 on board the NASA/ESA Hubble Space Telescope, shows the globular cluster Terzan 1. Lying around 20 000 light-years from us in the constellation of Scorpius (The Scorpion), it is one of about 150 globular clusters belonging to our galaxy, the Milky Way. Typical globular clusters are collections of around a hundred thousand stars, held together by their mutual gravitational attraction in a spherical shape a few hundred light-years across. It is thought that every galaxy has a population of globular clusters. Some, like the Milky Way, have a few hundred, while giant elliptical galaxies can have several thousand. They contain some of the oldest stars in a galaxy, hence the reddish colours of the stars in this image — the bright blue ones are foreground stars, not part of the cluster. The ages of the stars in the globular cluster tell us that they were formed during the early stages of galaxy formation! Studying them can also help us to understand how galaxies formed. Terzan 1, like many globular clusters, is a source of X-rays. It is likely that these X-rays come from binary star systems that contain a dense neutron star and a normal star. The neutron star drags material from the companion star, causing a burst of X-ray emission. The system then enters a quiescent phase in which the neutron star cools, giving off X-ray emission with different characteristics, before enough material from the companion builds up to trigger another outburst.

 por Magus, poeta invitado

Siento el silencio

que traspasa edades y laberintos

no se escucha

ni el palpitar de un lamento

ni el crujir de una hoja

solo un vacío solitario

donde la eternidad es un punto indefinido

que nunca se repite

todos los misterios han sido develados

el parir de las estrellas

la levedad del tiempo

siento en mí todo el dolor ajeno

pero también

me llenan las alegrías

de todos aquellos que vivieron

de los que están

y de los que un día vendrán

a cosechar sus propios recuerdos,

llevo grabadas en mí

todas las estaciones de la tierra

el calor ferviente del verano

la lucidez infinita de la primavera

las hojas caídas del otoño

las forma cadenciosas de la nieve en invierno,

yo, que ya lo he vivido todo,

puedo seguir viviendo a través de tus ojos

que me muestran lo que dejé atrás

lo que aflora de la belleza de la tierra

y la música que hace el mundo

al vibrar contra las estrellas,

tengo más cosas para decir

pero por ahora mis sentidos yacen abrumados

sabiendo lo que hay más allá del infinito…
