“Spread Knowledge, It Is Power, It Is Free”
From the lives of the stars to creation theories, functions of the human brain, and the ongoing search for extraterrestrial intelligence, Cosmos asks big questions. When appropriate, Sagan offers big answers, or asks still bigger–and yes, even spiritual–questions at the boundaries of science and religion.
What’s most remarkable about Cosmos is that it remains almost entirely fresh, with few updates needed to the science that Sagan so passionately celebrates. It is no exaggeration to say that Cosmos–for all the debate it may continue to provoke–is a vital document for humanity at a pivotal crossroads of our history.
The complete landmark TV series – 13 one-hour episodes, including:
I: The Shores Of the Cosmos II: One Voice In the Cosmic Fugue III: The Harmony Of the Worlds IV: Heaven and Hell V: Blues For A Red Planet VI: Travellers’ Tales VII: The Backbone of Night VIII: Travels In Space and Time IX: The Lives Of the Stars X: The Edge Of Forever XI: The Persistence Of Memory XII: Encyclopedia Galactica XIII: Who Speaks For Earth?

“Remember the amazing night-time timelapse video that James Drake stitched together from space station photos? Well, he’s gone back through the astronaut photographs and created six more videos. They’re shorter… but they’re AMAZING. Daytime, night time, auroras, it’s all there. Check them out via UniverseToday.”

Nature The Sculptor: Science of Snowflakes
Just as with raindrops, a snowflake begins as a droplet of water which condenses on a speck of dust. The droplet freezes and more droplets condense and freeze on it (remember how ice will stick to your tongue?) If the cloud temperature stays below freezing, enough droplets will freeze and collect to form a snowflake. Because of the way water molecules fit together, most snowflakes are six-sided (hexagonal.) When the snowflake gets heavy enough, it descends to Earth.

PORTUGUESE MAN OF WAR & MAN OF WAR FISH
Physalia physalis & Nomeus gronovii
© Seth PattersonThe Portuguese Man o’ War is not one animal, but is actually comprised of colonies of invertebrate, jelly-like marine animals of the family: Physaliidae glomming together. These pelagic hydroids (or hydrozoans) colonize and are infamous for their very painful, powerful sting.
It would seem wise for marine life to steer clear of the Man of War’s stinging tentacles however it shares an interdependence with a variety of transient marine fish, including shepherd fish, clownfish, yellow jack and one fish specialized to live within its tentacles—the man of war fish.
The man-of-war fish is generally found in open sea or close to the Portuguese man of war, after which it is named. It is found in all tropical and subtropical oceans.
The fish is striped with blackish-blue blemishes covering its body, and the caudal fin is extremely forked. It grows to a length is up to 15.5 inches (39 cm).
As unlikely as it seems, this fish, rather than using mucus (like the clownfish) to prevent stings, appears to uses highly agile swimming to physically avoid tentacles. The fish has a very high number of vertebrate (41), which adds to its agility and uses its pectoral fins for swimming — a feature common in fish who specialize in maneuvering in tight spaces. It also has a complex skin design containing at least one antigen to the man-of-war’s stinging toxin. The fish seems to be ten times more resistant to the toxin than other fish.
