Damien Chazelle’s “First Man,” Reviewed | The New Yorker

Chazelle, true to the title, and more intimate in his dramatic scope than Kaufman, is consumed by the curious case of Armstrong, forsaking all others. Long before he becomes the only man on the moon, he looks like the loneliest man in America.

If Armstrong is merely a name to you, take a look at the real Neil: those broad unfazeable features, the undemanding steadiness of the gaze, and a mouth that is happy, if conditions are favorable, to curve into a smile. Now consider Gosling—the sad-eyed heartthrob, a veteran of The Notebook (2004), and a tender presence who can’t help drawing us into his plights.

Recruiting Gosling to its emotional cause, First Man proceeds on the assumption that folk who are modest in displaying their feelings, like Armstrong, must by definition be deeply repressed and taut with untold misery. But they’re not. They’re just modest.

If Earth-like planet Proxima b has life, what might it be like? | New Scientist
With one face permanently turned to Proxima Centauri, Per Ardua’s “substellar point”, directly beneath the star, is a focus of climate patterns. Around it lie concentric bands of types of life, adapted to set levels of starlight, with analogues of tropical forest at the centre, and temperate forest and taiga further out. From space the planet looks like an archery target broken up across oceans.

An Exoplanet Too Far - The New Yorker
Anglada-Escudé and his colleagues estimate that Proxima b is at least 1.3 times as big as Earth and is most likely a terrestrial planet, with a surface. It orbits its star at a dizzying pace, once every eleven days, at a distance twenty times closer than Earth is to the sun. But, because the star is much dimmer than the sun, the average temperature on Proxima b could potentially be temperate and the orbit “is within the range where water could be liquid on its surface,” the researchers write in their Nature paper.

The planet is also likely tidally locked, like our moon, with one side permanently in light; good luck to anyone doomed to live on the frigid dark side.

In fact, it wouldn’t even be there by the time we arrived. Stars wander ever so slightly, and the cosmos as a whole is expanding; in the next eighty thousand years, Proxima Centauri and its planet will have moved two light-years farther from Earth, adding another forty thousand years to the trip. “The universe is moving,” Pedro Amado, of the Instituto de Astrofísica de Andalucía, said yesterday.

NASA releases new composite image of Titan, showing Earth-like surface of Saturn's largest moon - ABC News (Australian Broadcasting Corporation)
Cassini flew as close as 10,000 kilometres to the "rich and complex" world of Titan during the November 13 flyby, which was considerably higher than typical flybys at 1,200 kilometres but allowed the spacecraft to capture moderate-resolution views over wide areas, with a resolution of a few kilometres per pixel.

The colours in the image are false and represent the wavelengths of light collected by Cassini's visual and infrared mapping spectrometer (VIMS) instrument, from blue at 1.3 microns, through green at 2.0 microns, to red at 5.0 microns.

Visible light is centred around 0.5 microns.

Methane, a compound of carbon and hydrogen, is broken down by cosmic radiation in Titan's upper atmosphere, contributing to the orange haze that obscures the surface from visible light.

Home, sweet exomoon: The new frontier in the search for ET
Then there is the effect known as tidal heating. In a system with more than one moon, varying gravitational pulls as the bodies orbit the central planet can stretch and squeeze a moon’s interior, causing friction that can generate enormous internal heat. (Our moon’s smaller pull doesn’t generate much heat, but does create ocean tides.) Such effects could extend the region around a star in which liquid water can exist well beyond the habitable zone towards a “habitable edge” much further out.

Our Cosmic Selves -
That discovery is relatively recent. Four astrophysicists developed the idea in a landmark paper published in 1957. They argued that almost all the elements in the periodic table were cooked up over time through nuclear reactions inside stars — rather than in the first instants of the Big Bang, as previously thought. The stuff of life, in other words, arose in places and times somewhat more accessible to our telescopic investigations.

Since most of us spend our lives confined to a narrow strip near Earth’s surface, we tend to think of the cosmos as a lofty, empyrean realm far beyond our reach and relevance. We forget that only a thin sliver of atmosphere separates us from the rest of the universe.

Up to half the water on our planet is older than the solar system itself. Ancient water molecules assembled in the chilly confines of a gigantic gas cloud. That cloud spawned our sun and the planets that orbit it — and somehow those ancient water molecules survived the perils of the planetary birth process to end up in our oceans and, presumably, our bodies.

Together, these findings raise the odds that life’s building blocks were concocted in space and blended into the material that formed Earth and its planetary siblings.

Amid the material comforts and the relentless distractions of modern life, the universe at large may appear remote, intangible and irrelevant, especially to those of us who are city dwellers. But the next time you catch a glimpse of the Milky Way in its true glory, from a dark outpost far from city lights, think of those countless stars as nuclear factories and the starless hazy patches as molecular breweries. It is not much of a stretch to imagine the inchoate seeds of life emerging in the distance.

Can science prove the existence of God? — Starts With A Bang! — Medium
In other words, life is a fantastic bet, but intelligent life may not be. And that’s according to reasonable scientific estimates, but it assumes we’re being honest about our uncertainties here, too. So the conditions for life are definitely everywhere, but life itself could be common or rare, and what we consider intelligent life could be common, rare or practically non-existent in our galaxy. As science finds out more, we’ll learn more about that.

The truths of the Universe are written out there, on the Universe itself, and are accessible to us all through the process of inquiry. To allow an uncertain faith to stand in as an answer where scientific knowledge is required does us all a disservice; the illusion of knowledge — or reaching a conclusion before obtaining the evidence — is a poor substitute for what we might actually come to learn, if only we ask the right questions. Science can never prove or disprove the existence of God, but if we use our beliefs as an excuse to draw conclusions that scientifically, we’re not ready for, we run the grave risk of depriving ourselves of what we might have come to truly learn.

Bound for Pluto, Carrying Memories of Triton -
Triton was a fitting capstone to the Voyager adventures, at least here in the solar system. Voyager 2 and its twin, Voyager 1, were launched in 1977 to take advantage of a rare once-in-175-year alignment of Jupiter, Saturn, Uranus and Neptune to tour the outer solar system. In addition to cameras and other gear, each carried a gold record (and instructions on how to play it) with sights and sounds of Earth, including a kiss, as greetings for whoever or whatever was Out There.

Voyager 1 departed the tour early, having detoured to inspect Saturn’s misty moon Titan, and then headed for the stars. Voyager 2 kept going past Uranus and Neptune before looping outward past Triton. The Voyagers cruised on, during wars, recessions, the inauguration of the space shuttle, the crack cocaine epidemic and Ronald Reagan’s “morning in America.” At every planetfall the Voyager scientists, like a graying tribe, reassembled at the Jet Propulsion Laboratory in Pasadena, Calif., for a refresher course on nature’s repertoire.

Today astronomers agree that the leading candidates besides that old standby Mars for harboring life outside Earth – at least in our solar system – are moons of Saturn or Jupiter: the ocean of Europa, jets of water squirting from Saturn’s moon Enceladus, or even in the methane snowdrifts and lakes of Titan.
