SH2-170.jpgSH2-17082 visite"...Non so che farmene del tuo Dio.
Anzi: non so che farmene di un Dio, il tuo come quello di qualsiasi altro.
Un "Dio" che guarda e che, dall'alto della Sua Onnipotenza, Bontà e Saggezza, lascia che le sue pecore si scannino fra loro nel nome di Lui o nel nome dell'interesse del gregge a cui esse appartengono, è solo un vigliacco, un ipocrita, un nulla.
Il Dio nel quale credi tu e tanti altri assieme a te, non è nulla più di una parola, vuota ed abusata.
Accetta la realtà: c'è molto più Dio nella Fede di coloro che sono morti nel Suo Nome e nelle pietre usate per erigere le Sue Cattedrali, di quanto io ne veda nella candida immagine che tu, vanamente, continui a temere e supplicare...".

Nebulae.jpgThe "Ant Nebula" & companions69 visite"...Nelle immagini dipinte nei miei ricordi - immagini che ora vedo più limpide che mai - lo Spazio, il Tempo e la Natura stessa, parevano flettersi davanti al potere della mia Speranza, della mia Voglia, della mia Immaginazione.
Rondini e passeri si confondevano nell'azzurro del cielo; e prati verdi e fioriti, freschi di rugiada, accoglievano i miei passi titubanti.
Silenzi scolpiti nella Terra e raggi di Sole, gialli ed intensi, scherzavano sull'acqua delle fontane.
Attraente, guizzante ed inafferrabile, come un sogno troppo bello, il Futuro mi stava aspettando..."

Timeline.jpgThe Timeline of the Universe77 visiteThe Universe is expanding gradually, now, but its initial expansion was almost impossibly rapid as it likely grew from quantum scale fluctuations in a trillionth of a second. In fact, this cosmological scenario - known as "Inflation" - is now reported to be further quantified by an analysis of 3 years of data from the WMAP Spacecraft. WMAP's instruments detect the Cosmic Microwave Background Radiation - such as the afterglow light from the early Universe. WMAP's amazing success in exploring the first trillionth of a second and favoring specific inflationary scenarios, lies in its ability to make unprecedented, precise measurements of the properties of the Microwave Background. The subtle properties are distilled from conditions in the early Universe and related to its first moments of existence. Schematically, this diagram traces the 13,7 BY (plus a trillionth of a second) history of the Universe from the quantum scale to the formation of stars, galaxies, planets and WMAP itself.

Z machine_sandia_big-1.jpgThe Heart of a Star...On Earth: the Z Machine129 visiteWhy is this plasma so hot? Physicists aren't sure. What is known for sure is that the Z Machine running at Sandia National Laboratories created a plasma that was unexpectedly hot. The plasma reached a temperature in excess of two billion Kelvin (!), making it arguably the hottest human made thing ever in the history of the Earth and, for a brief time, hotter than the interiors of stars. The Z Machine experiment, pictured above, purposely creates high temperatures by focusing 20 million amps of electricity into a small region further confined by a magnetic field. Vertical wires give the Z Machine its name. During the unexpected powerful contained explosion, the Z machine released about 80 times the world's entire electrical power usage for a brief fraction of a second. Experiments with the Z Machine are helping to explain the physics of Solar flares, design more efficient nuclear fusion plants, test materials under extreme heat, and gather data for the computer modeling of nuclear explosions.

OGLE.jpgOGLE 2005-BLG-390Lb - ExtraSolar Planet74 visiteThis Artist's illustration shows an icy/rocky planet orbiting a dim star. Astronomers detected an Extrasolar Planet that is five times as massive as Earth, circling a red dwarf - such as a relatively cool star - every 10 years. The distance between this Planet, designated OGLE-2005-BLG-390Lb, and its host is about 3 times greater than that between the Earth and the Sun (means about 240/250 MKM).
The Planet's large orbit and its dim parent star probably make its surface temperature a frigid -364° Fahrenheit (about -220° Celsius).

D-RAD.jpgDeinococcus Radiodurans: the "Terra-Farmers"...88 visiteThese bacteria could survive on another planet. In an Earth lab, Deinococcus Radiodurans (D. Rad) survive extreme levels of radiation, extreme temperatures, dehydration, and exposure to genotoxic chemicals. Amazingly, they even have the ability to repair their own DNA, usually within 48 hours.
Known as an extremophile, bacteria such as D. Rad are of interest to NASA partly because they might be adaptable to help human astronauts survive on other worlds. A recent map of D. Rad's DNA might allow biologists to augment their survival skills with the ability to produce medicine, clean water and oxygen.
Already they have been genetically engineered to help clean up spills of toxic mercury. Likely one of the oldest surviving life forms, D. Rad was discovered by accident in the 1950s when scientists investigating food preservation techniques could not easily kill it.
In the picture above: Deinococcus radiodurans grow quietly in a dish.
