Nebraska Astronomy Applet Project: Extrasolar Planets Lab - Feb 1, 2012

Visit Nebraska Astronomy Applet Project: Extrasolar Planets Lab to try to simulations of how extrasolar planets are detected indirectly--that is, without making an image of the planet.

Also, check out Planet Quest Interactives, and click on one of the simulations. You can choose from Extreme Planet Makeover, Planet Quest Timeline, and Alien Safari.

Bottled tornado - Jan 1, 2012

Make your own vortex at home--see Bottled tornado for how to do it. And be sure you have an adult with you.

Alternately, you can purchase a connector for the two bottles, with a hole in the middle--just google "vortex bottle" to find a vendor.

A Magnet That Drips: Making Ferrofluids - Dec 1, 2011

Ferrofluids like the ones pictured above are not difficult to make--you can prepare your own by following the instructions at A Magnet That Drips: Making Ferrofluids. Since the ferrofluid will be messy, make sure your work area is easy to clean. Also, be sure you have an adult working with you.

Space Topics: Extrasolar Planets--Searching Methods - Feb 1, 2012

There are five ways to detect an extrasolar planet:
--observing periodic changes in the frequency of the spectra lines at the star emits
--observing the periodic dimming of the star when the planet passes in front of the star
--observing periodic changes in the position of the star the planet orbits
--observing an enhanced image of the planet with gravitational lensing
--making a "direct" image of the extrasolar planet

Visit Space Topics: Extrasolar Planets--Searching Methods to learn about each of these methods.

Also, astronomers now believe our galaxy has more planets than stars--see this BBC Report.

How Airplanes Fly: A Physical Description of Lift - Jan 1, 2012

Visit the Florida International University site How Airplanes Fly: A Physical Description of Lift to understand how the wing of an airplane produces lift. You'll see that the frequently-given explanation based on the Bernoulli principle is not correct.

Morpho Towers, Two Standing Spirals - Dec 1, 2011

This YouTube video, "Morpho Towers, Two Standing Spirals," by Sachiko Kodama, shows a ferrofluid work of art. You can see the video at Morpho Towers, Two Standing Spirals, and learn more about it by visiting this webpage.
