galassie a perdere

Not to be confused with our neighbouring Andromeda Galaxy, the Andromeda constellation is one of the 88 modern constellations. More importantly for this image, it is home to the pictured NGC 7640. Many different classifications are used to identify galaxies by shape and structure — NGC 7640 is a barred spiral type. These are recognisable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s centre. Our home galaxy, the Milky Way, is also a barred spiral galaxy. NGC 7640 might not look much like a spiral in this image, but this is due to the orientation of the galaxy with respect to Earth — or to Hubble, which acted as photographer in this case! We often do not see galaxies face on, which can make features such as spiral arms less obvious. There is evidence that NGC 7640 has experienced some kind of interaction in its past. Galaxies contain vast amounts of mass, and therefore affect one another via gravity. Sometimes these interactions can be mild, and sometimes hugely dramatic, with two or more colliding and merging into a new, bigger galaxy. Understanding the history of a galaxy, and what interactions it has experienced, helps astronomers to improve their understanding of how galaxies — and the stars within them — form.

quanti segni nell’ombra
quante voci
senza traccia perdute

steli e stelle disseminate
galassie a perdere
spirali e torrioni nell’infinito
nero del tempo

meteore ripescate dal nulla
vertiginosi viaggi nell’oltre, ammassi
in lattea diffusione – risucchi
in formazione rapida
già
polverizzati

Van Gogh

Van Gogh

Camminerò verso un mare notturno
sotto stelle rotanti e lune arancio
come in un quadro di Van Gogh

il pizzicato di un violoncello solleverà
onde a virgola, bianche e aguzze
ci saranno gli scogli di Etretat

niente sarà reale
solo il battito del mio cuore

avanzando nel liquido nero
vibrazioni profonde mi laveranno
toccherò il limite tra morte e vita

notti di solstizio ambiguo e lune sfatte,
al franare dei sensi rispondono
segnali di tarlo –
piegata nel vano della finestra
trema la tua figura:
s’apre alla nebbia notturna il vetro
un ricordo ti avvolge, ridi
stelle di neve al suolo
cadono polverizzate
