«But on Pluto, with its thin atmosphere, I think any condensed particles would be very small, perhaps microns in size, so they would probably not
form as snowflakes.
Not exact matches
It starts out
as micro being individual
snowflakes that are falling and gather stacking one on top of another
forming a mass just waiting for a single dog bark or branch crack to set it off down the mountain in very macro fashion.
The size and shape of a
snowflake depends mainly on temperature and the amount of water vapor available
as they
form.
Libbrecht is interested in what happens on a molecular level when ice crystals
form, but he sees it
as an old - fashioned scientific pursuit: «It's really like doing science 100 years ago,» he says, in that he's studying a mystery inherent in the mundane and familiar
snowflakes that flutter from the sky each winter.
But it left an open question: Were airborne microbes
forming ice in the clouds, or were they merely getting mopped up by
snowflakes as they fell to Earth?
In reality, there are many different types of
snowflakes (
as in the clich that «no two
snowflakes are alike»); this differentiation occurs because each
snowflake is a separate crystal that is subject to the specific atmospheric conditions, notably temperature and humidity, under which it is
formed.
When they practically stop moving, the molecules
form crystals, like those you see creating frost on your windows or drifting from the sky
as snowflakes.
Whereas Earth ice, like
snowflakes, always
form hexagonal crystals, space ice can
form many different crystal shapes, such
as this «palm tree» formation [right].
As the inner regions of the protoplanetary disk cooled below 3,000 degrees Fahrenheit, they reasoned, those elements condensed out of the hot vapor to form delicate mineral crystals, just as the intricate branches of a snowflake condense from water vapo

Snowflakes, for instance,
form differently
as they fall, depending on variable conditions such
as temperature and humidity, hence the widely held belief that no two are alike.
At the extremely low surface temperatures on these objects, water ice takes a disordered, amorphous
form instead of the regularly ordered crystals typical in warmer areas, such
as snowflakes on Earth.
The newly revealed infant stars appear
as pink and red specks toward the center and appear to have
formed in regularly spaced intervals along linear structures in a configuration that resembles the spokes of a wheel or the pattern of a
snowflake.
Entering the galleries, visitors are invited to explore connections between a kaleidoscope of seemingly disparate objects such
as Bentley's
snowflake photographs, Shaker spirit drawings, Tibetan mandalas, Kabbalistic diagrams, and a wall - hanging by Iranian artist Monir Shahroudy Farmanfarmaian called First Family — Hexagon (2010) that uses six - sided
forms.
Wilson's intricate works draws inspiration from
forms and patterns already found in nature, such
as diatoms, they fractal
forms of
snowflakes, and from cymatics, the visual patterns of sound and vibration.
