RS Ophiuci.jpgRS Ophiuci58 visite"...A novel is balanced between a few true impressions and the moltitude of false ones that make up most of what we call Life.
It tells us that for every human being there is a diversity of existences, that the single existence is itself an illusion, in part...
It promises us meaning, harmony, and even justice..."

Nebulae.jpgThe "Ant Nebula" & companions60 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 Universe65 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.

OGLE.jpgOGLE 2005-BLG-390Lb - ExtraSolar Planet65 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"...77 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.
