Jedan od motiva za otvaranje ove teme je upravo ova izjava mog najomiljenijeg SF autora i naucnika.

I ja delim njegovu nadu, mada mi je “strepnja jaca od nade” kako rece jedan od onih na koje se upravo ovi citati odnose.

“We all know the narrow, limited type of mind that is interested in nothing beyond its town or village and bases its judgments on those parochial standards. We are slowly – perhaps too slowly – evolving from that mentality toward a world outlook. Few things will do more to accelerate that evolution than the conquest of space. It is not easy to see how the more extreme forms of nationalism can long survive when men begin to see the Earth in its true perspective as a single small globe among the stars.”

“The future is built on the rubble of the past; wisdom lies in facing that fact, not in fighting against it.”

Nikad nisam citao Clarka, ali me je zato odusevio Kosmos u orahovoj ljusci, Stivena Hokinga.... Iako su mi pojedina poglavlja ostala potpuno out of reach, ona ostala koja sam razumeo su me potpuno fascinirala......

Hubble Telescope Captures 'Light Echo'

Feb. 7, 2005 — The Hubble Space Telescope has captured images of never-before-seen interstellar dust patterns as a brightening star illuminates its surrounding dust clouds.
The red supergiant star, called V838 Monocerotis (V838 Mon), suddenly became 600,000 times more luminous than our sun for several weeks in early 2002, like a flashbulb set off in a dark room, according to a NASA press release.
A previous explosion of the star, similar to the 2002 pulse, may have ejected the dust that surrounds V838 Mon, NASA said.
The effect, called a light echo, happens when light from a stellar explosion expands outward, illuminating different parts of the surrounding dust, NASA said, likening it to the echo of sound through air. Eventually, the light will disappear.
V838 Mon is located at the outer edge of our Milky Way galaxy, about 20,000 light-years away from Earth in the direction of the constellation Monoceros.
Hubble has taken images of V838 Mon and its light echo several times since the star's outburst. Each time the telescope observes the event, different thin sections of the dust are illuminated as the light continues to expand away from the star.

The Life Story of Two Bright Stars

Standing upright and shining down upon us through the frosty air, high in our southern sky at around 8 p.m. is the brightest and grandest of all the constellations, Orion, the Mighty Hunter.
Three bright stars in line in the middle of a bright rectangle decorate Orion’s belt, which points northward to the star clusters of the Hyades and Pleiades of Taurus, and southward to the Dog Star Sirius [discussed last week]. It is here that we also find two immense stars, Rigel and Betelgeuse.
Rigel (the "Left Leg of the Giant"), is a blue-white supergiant star, one of the rarest breeds in our galaxy. But with their enormous brilliance – up to 100,000 times that of the Sun – these stars remain conspicuous over great distances.
In contrast, red supergiants like Betelgeuse ("The Armpit of the Giant") are gigantic bloated globes of cooler gas. If such a star were to replace the Sun in the solar system, it might extend beyond Mars’ orbit.
