Cassini Significant Events 04/18/07 – 04/24/07 April 26, 2007 (Source: Cassini Project) The most recent spacecraft telemetry was acquired on Tuesday, April 24, fromthe Goldstone tracking complex. The Cassini spacecraft is in an excellentstate of health and all subsystems are…
First 3-D Vews of the Sun
For millennia, we on Earth have seen the Sun as a flat disk in the sky. Now, for the first time, we are seeing the Sun in three dimensions, thanks to the recently launched twin Solar Terrestrial Relations Observatory (STEREO)…
Titan Flyby – Apr. 26, 2007
Cassini’s radar eyes imaged additional regions near Titan’s north pole during an April 26, 2007, flyby.
Lakes Drain under Antarctic Ice Sheet
Throughout Antarctica, broad ribbons of ice known as ice streams shed large quantities of ice into the ocean.
The Carina Nebula: Star Birth in the Extreme
BACKGROUND INFORMATION: HUBBLE’S TOP SCIENCE FINDINGS (An interactive version of this document is available in the “Related Links” section of this release.)When Galileo used his homemade telescope 400 years ago to view mountains on the Moon, satellites circling Jupiter, and…
Something Under the Ice is Moving
Satellites measurements of ice sheet elevation reveal a complex network of subglacial lakes in Antarctica. As water flows from lake to lake, the ice sheet above them rises and falls.
Venice, Italy
A space-based perspective of the city of Venice quickly reveals different development and land uses in the region; the major islands in the lagoon surrounding Venice—Laguna Veneta—look different from one another. The island of Venice itself, a dense urban landscape,…
Chankillo Observatory, Peru
About 400 kilometers (250 miles) north of Lima, Peru, lies an enigmatic, 2,300-year-old ruin named Chankillo. Archaeologists have nicknamed the ruin’s central complex the “Norelco ruin” based on its resemblance to a modern electric shaver. The building’s true purpose long…
Earthquake Raises Ranongga Island
In the early morning hours of April 2, 2007, a magnitude 8.1 earthquake shook the Solomon Islands, its epicenter southwest of Ranongga Island. The huge quake pushed much of the island up, raising the coral reefs that ringed the island…
Dust Storm in Southern California
Along historic Route 66, just southeast of the little town of Amboy, California, lies a dried-up lake. Dry lakebeds are good sources of two things: salt and dust. In this image, the now-parched Bristol Lake offers up both.
Sweat Farm Road Fire, Georgia
According to reports from the Southern Area Coordination Center, the Sweat Farm Road Fire in southern Georgia exploded from 1,000 acres to more than 20,000 acres in less than 24 hours between April 16 and 17, 2007. Strong winds whipped…

Dust Dampens Hurricane Formation
Warm sea surface temperatures help fuel hurricanes, and in 2006, those temperatures were cooler than expected. Why the difference between 2005 and 2006? William Lau of NASA Goddard Space Flight Center and Kyu-Myong Kim of University of Maryland-Baltimore County think…
