Cassini Liked It So He Put A Ring On It

If you've seen a recent photo of Saturn (such as the one above), it's likely from the Cassini spacecraft. The 10th anniversary of the Cassini spacecraft reaching the Saturn system (the planet and its moons) occurred on June 30th.  The spacecraft is named after Giovanni Cassini, an accomplished scientist who, among other things, noted a gap between the rings of Saturn now known as the Cassini Division. This is the dark area within the rings of the above photo.

Ten years later, and our understanding of our system has been greatly enhanced by the discoveries of the Cassini spacecraft. Check out an infographic followed by the top 10 accomplishments of the program:

Below are the top accomplishments from the Cassini spacecraft in the past 10 years:

-- The Huygens probe makes first landing on a moon in the outer solar system (Titan)

-- Discovery of active, icy plumes on the Saturnian moon Enceladus

-- Saturn’s rings revealed as active and dynamic -- a laboratory for how planets form

-- Titan revealed as an Earth-like world with rain, rivers, lakes and seas

-- Studies of Saturn's great northern storm of 2010-2011

-- Studies reveal radio-wave patterns are not tied to Saturn’s interior rotation, as previously thought

-- Vertical structures in the rings imaged for the first time

-- Study of prebiotic chemistry on Titan

-- Mystery of the dual, bright-dark surface of the moon Iapetus solved

-- First complete view of the north polar hexagon and discovery of giant hurricanes at both of Saturn's poles

#Cosmos E13 - World B Free

Well ... that's it. Cosmos is done!  On one hand, it means that I can return to regular science blogging on this site.  I am sad though - it's truly been a great experience to share this show with you and others that realize the impact that science has in your life.  Congratulations to Fox, Seth McFarlane, Neil deGrasse Tyson, Ann Druyan, and everyone else that made this series possible.

Check out a video from the show discussing the Alexandria Library.  Below the video is the Storify live tweet that I hosted on Sunday.

#Cosmos E12 - Let's Get Free

Episode 12 of Fox's Cosmos focuses on the scientific rationale for climate change. The greenhouse effect, which was one of the main scientific endeavors of the original Cosmos host Carl Sagan, is when gas in the atmosphere traps sunlight bouncing off of the Earth's surface. Modern civilization burns fossil fuels which adds more carbon to the air, helping the atmosphere get even warmer.  Check out this video below for a visual explanation of the greenhouse effect.

 

Look below for more video blurbs from Cosmos, as well as the live Storify twitter chat that we held during the show's viewing.

#Cosmos E11: Eternalists

(I live tweet Cosmos every Sunday @ 8pm CST. For all of my Cosmos recaps, please click here)

Episode 11 of Fox's Cosmos, "The Immortals", focuses things that stand the test of time - the first written word, stories, and organisms that can survive for millenia. All these things stand the test of time - and could possibly have extraterrestrial origins.

Early in the formation of our solar system, Earth and the other planet were slammed by asteroids and other rocks.  Rocks were flying all over the place, and organisms were along for the ride - possibly exchanging life between the planets.

#Cosmos E10: Electric Circus

Before this week's Cosmos, I was featured on the Black Girl Nerds podcast with Danielle Lee.  We talked Cosmos and other science issues - check it out the podcast below as well as the accompanying Storify!

 

Episode 10 of Fox's Cosmos is titled "The Electric Boy" - and luckily has no tie in Jamie Foxx's Electro from The Amazing Spiderman 2. We see how the first electric motor and generator were created based on the observations and experiments of scientists such as Michael Faraday and Humphry Davys. With the added math of James Maxwell, the world was ready to harness the part of electricity in useful ways.
