These two exoplanets might be completely covered in water

http://news.harvard.edu/gazette/story/2013/04/water-worlds-surface/

“In our solar system, only one planet is blessed with an ocean: Earth. Our home world is a rare, blue jewel compared with the deserts of Mercury, Venus, and Mars. But what if our sun had not one but two habitable ocean worlds?

Astronomers have found such a planetary system orbiting the star Kepler-62.  This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth that liquid water could theoretically exist on their surfaces. Modeling by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that both planets are water worlds, their surfaces completely covered by a global ocean with no land in sight.”

Wringing out a Washcloth on the ISS

Space Canadian Chris Hadfield continues his quest for interplanetary internet dominance with this incredible experiment submitted by two Nova Scotia high school students: Kendra Lemke and Meredith Faulkner

They wanted to know what would happen if you wrung out a washcloth on the ISS? I won’t spoil the ending for you, but suffice to say it’s about the coolest thing I’ve ever seen.

I love how he doesn’t even have to hold the mic. Great job, Kendra and Meredith! For science!

March 22nd (tomorrow) is World Water day.
From the United Nations website, “World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED). The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.”
