“Massive galaxies warp space-time around themselves, bending light rays so that we can see around them. They’re the Universe’s own telescopes, but these gravitational lenses are very rare: we need your help to find them!”
Corporate marketing from IBM - “A Boy And His Atom: The World’s Smallest Movie.” Even though I usually don’t reblog corporate content, it is still pretty interesting.

“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.”
President Obama Stresses Importance of Science and Technology to the Nation’s Future.
“On April 29, 2013 - President Barack Obama reiterated his strong support for science and technology in this speech to members of the National Academy of Sciences at its 150th annual meeting. Science, technology, engineering, and medicine are critical to the nation’s prosperity, Obama said, noting that investments made today are bound to pay off for many years to come.”

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!

April is Earth Month, so says NASA. The image is from NASA, too.
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.”

Want to see a comet in the next week or two? Comet PANSTARRS will be visible starting today till the end of the month. The image is from the University of Hawaii. Another good place to find observing information is at Sky & Telescope magazine.
