Listening for Gravity Waves, Silence Becomes Meaningful Aug 27, 2009
ARMED FOR DISCOVERY: At the LIGO site in Louisiana, a pair of four-kilometer-long arms [one of which stretches toward the top of this photograph] awaits the telltale elongation or compression of a passing gravity wave. A similar observatory in Washington State is also on the case. (Scientific American)
Star bright, star light: Planet Venus is back in all her blinding glory Jun 5, 2009
When Venus is visible it is called an elongation: an eastern elongation when it can be seen in the evening and a western elongation when it can be seen in the morning hours. "On June 16 Venus will be three degrees away from a crescent moon in the sky,'' Schmidt said. "It won't look like a round disk at all. (Racine Journal Times, WI)

Hence Venus becomes even better placed for Northern Hemisphere observers many weeks after its greatest elongation from the sun on June 5. At latitude 40 degrees north, for example, the planet will rise three hours ahead of the sun on July 31, attaining an altitude of 32 degrees at sunrise. (MSNBC -- Technology)

So now, about four days after it passed nearly in front of Saturn and cast its shadow onto the planet, you'll find Titan is at its western elongation, about four ring-lengths to Saturn's west. Friday, April 17. (SkyAndTelescope.com)
Desperately seeking Mercury Apr 4, 2009
It reaches greatest eastern elongation its greatest angular distance east of the sun (20-degrees) on April 26. Shining then at magnitude +0. (MSNBC -- Technology)

Friction decreasing outward from the center of the edifice can explain the overall "circus tent" shape, whereas friction decreasing from southeast to northwest accounts for the shortening and elongation of the respective quadrants. The most likely origin for the basal low-friction zone is in a layer of clay sediment, overpressured by pore water. (Science Daily)
