Cumulonimbus Cloud over Africa
Perhaps the most impressive of cloud formations, cumulonimbus (from the Latin for “pile” and “rain cloud”) clouds form due to vigorous convection (rising and overturning) of warm, moist, and unstable air. Surface air is warmed by the sun-heated ground surface…
Cassini Spacecraft to Dive Into Water Plume of Saturn Moon
Cassini Spacecraft to Dive Into Water Plume of Saturn Moon March 10, 2008 (Source: NASA/JPL) This graphic shows the trajectory for the Cassini spacecraft during its close brush with the icy outpost of Enceladus on March 12, 2008. At closet…
Ries Crater, Germany
Germany’s Ries Crater (or Nördlinger Ries) is not easily discerned in space-based images. The crater’s existence was probably just as subtle to the medieval Europeans who established a settlement inside it and unknowingly matched their 1-kilometer- (0.6-mile-) wide city to…
Tropical Cyclone Jokwe
The compact Tropical Cyclone Jokwe had just skimmed past northern Madagascar and was moving south into the Mozambique Channel when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this photo-like image on March 7, 2008. Loose bands…
Amazon Fires on the Rise
In 2006, fires and smoke in the Amazon declined significantly for the first time in nearly a decade. Is Amazon burning under control?
Deforestation in Monarch Butterfly Reserve
Each year millions of monarch butterflies migrate thousands of miles back and forth from wintering grounds in Mexico to their breeding locations in the eastern United States and Canada. In the fall, the monarchs return to just 12 forested mountaintops…

Cassini Significant Events 02/27/08 – 03/04/08 March 7, 2008 (Source: Cassini Project) The most recent spacecraft telemetry was acquired on Tuesday, March 4, from the Madrid tracking complex. The Cassini spacecraft is in an excellent state of health and all…
Fire Damages Kenya’s Lake Nakuru National Park
In late February 2008, Kenya’s Lake Nakuru National Park suffered a major blow when an accidental fire scorched a large section of the relatively small park.
Enceladus: What Lies Beneath?
Until recently, Saturn’s tiny moon Enceladus was thought to be cold and dead. But close observations by the Cassini spacecraft have revealed dramatic features and made this frozen world a new target in NASA’s search for life. With a diameter…
Saturn Science Waits for No One
Todd J. Barber, Cassini lead propulsion engineer Hello again from Cassini flight operations! Like most of America, I’ve been somewhat incapacitated by the virulent flu bug making the winter rounds this year. Please forgive my three-week hiatus from this column…
Algae Bloom in Antarctic Sea Ice
In polar environments, tiny algae and other plant-like organisms that are the foundation of the ocean food web grow not just in the open ocean, but also within brine-filled pores and cracks in the sea ice. In the winter, sea…
Dust Storm over East Asia
March often brings an increase in dust storms to East Asia, and 2008 proved no exception. In early March 2008, the characteristic “yellow dust” from the Gobi Desert blew eastward over the Beijing region, the Yellow Sea, and North and…
The Last Confessions of a Dying Star
Probing a glowing bubble of gas and dust encircling a dying star, NASA’s Hubble Space Telescope reveals a wealth of previously unseen structures. The object, called NGC 2371, is a planetary nebula, the glowing remains of a Sun-like star. The…
