Con il suo combustibile nucleare quasi esaurito, la stella centrale della Hourglass Nebula (a forma di clessidra, appunto) si avvia a diventare una nana bianca e mentre espelle gran parte della propria materia superficiale, le rimane appena il tempo (su scala cosmica) per un’ultima strizzata d’occhio.

In the 1970s, NASA’s Ames Research Center gathered artists and asked them to imagine how feasible space colonies, able to accommodate about 10,000 people, might look. The results are here (here in high resolution) and this an example. Please note that Rendezvous with Rama by Arthur Clarke was first published […]
Il libro di Oliver Sacks, Musicofilia (Adelphi Ed., 2008-2009), è una miniera di aneddoti e considerazioni sulle più disparate affezioni che coinvolgono la percezione e l’apprezzamento della musica. Neurologo e psichiatra, ma anche membro onorario dell’Institute for Music and Neurologic Function, che ha contribuito a fondare, Sacks ha avuto fra […]
In particular conditions the sound waves can become visible. This Atlas V launched from Kennedy Space Center at Feb. 11 2010, fly through a sun dog. A sun dog is a prismatic bright spot in the sky caused by sun shining through ice crystals. The Atlas V rocket exceeded the […]
Nota: mi rendo conto che, in questi ultimi tempi, vi sto parlando un po’ poco di musica contemporanea e un po’ più di altre cose. Ciò è dovuto ad una certa noia che sto provando nell’ascoltare parecchie produzioni recenti. Passerà. Nel frattempo vi passo qualche consiglio che vi sarà di […]

ATLAS is a particle physics experiment at the Large Hadron Collider at CERN. Starting in late 2009/2010, the ATLAS detector will search for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning […]
May 16 1960: Theodore Maiman presented the first laser (Light Amplification by Stimulated Emission of Radiation) to the world. 50 years later, lasers are used in everyday life in fiber-optic communications, CDs/DVDs players, laser printers, laser medical procedures, and many more applications.
