Typhoons Mitag and Hagibis Drench the Philippines
Two tropical cyclones, Hagibis and Mitag, dumped heavy rain on the Philippines between November 19 and November 29, 2007. Known in the Philippines as “Lando” and “Mina,” respectively, the two storms caused at least 29 deaths as a result of…
Melting Anomalies on Greenland in 2007
The year 2007 marked an overall rise in the summertime melting trend over the highest altitudes of the Greenland ice sheet. Melting in areas above 2,000 meters (about 6,560 feet) rose 150 percent above the long-term average, with melting occurring…
NASA – Poof! How to Evaporate a Planet
Based on Hubble Space Telescope Release This artist’s illustration shows a dramatic close-up of the scorched extrasolar planet HD 209458b in its orbit only 4 million miles from its yellow, Sun-like star. The planet is a type of extrasolar planet…
NASA – Celestial Fireworks
View all images Resembling the puffs of smoke and sparks from a summer fireworks display in this image from NASA’s Hubble Space Telescope, these delicate filaments are actually sheets of debris from a stellar explosion in a neighboring galaxy. Hubble’s…
NASA – A Revealing Slant on Saturn’s Rings
When Galileo viewed Saturn through his telescope about 400 years ago, he wrote that the gas giant planet had “ears.” Those ears, elongated bulges on either side of the planet, were Saturn’s rings. Galileo could not discern the rings through…
Double Cyclones Strike Philippines
Typhoons Mitag (right) and Hagibis (left) flank the Philippines in this image taken by MODIS on November 25, 2007. At that time, Mitag was about to strike the Philippine island Luzon with winds of 150 kilometers per hour.
Holiday Wishes from the Hubble Space Telescope
Resembling festive lights on a holiday wreath, this NASA/ESA Hubble Space Telescope image of the nearby spiral galaxy M74 is an iconic reminder of the impending season. Bright knots of glowing gas light up the spiral arms, indicating a rich…

Cassini Significant Events 11/14/07 – 11/27/07 November 29, 2007 (Source: Cassini Project) Due to the Thanksgiving holiday, this report covers two weeks instead of the usual one week. The most recent spacecraft telemetry was acquired on Tuesday, Nov. 27, from…
Ferrar Glacier, Antarctica
Remote, frigid, and often treacherous to traverse, Antarctica has always posed a challenge to the explorers and scientists who work there. As a result, remote-sensing scientists have steadily worked to develop detailed, accurate imagery of the continent—both to support research…
Organic ‘Building Blocks’ Discovered in Titan’s Atmosphere
Organic ‘Building Blocks’ Discovered in Titan’s Atmosphere November 28, 2007 (Source: UCL’s Mullard Space Science) The thick, smog-like atmosphere of frigid Titan is a major source of interest for the Cassini mission. Scientists analysing data gathered by the Cassini spacecraft…
Seasonal Swings in Tropical Rainfall
Rainfall is the primary way the atmosphere spreads heat around. Not surprisingly, nearly two-thirds of all rain falls in the tropics, where incoming sunlight is steady year round. Sunlight evaporates water from the warm ocean and land surfaces. The water…
Isla Blanquilla, Venezuela
The small island of Blanquilla is named for its white sand beaches, visible in this astronaut photograph as a bright border along the northeastern–eastern shoreline. Surface currents extending from the western coastline of the island are caused by easterly trade…
Sacramento-San Joaquin River Delta
Many parties—endangered fish, thirsty Californians, and consumers who depend on produce from California’s Central Valley—all have a stake in the fate of Sacramento-San Joaquin River Delta. In the past, the delta would flood each spring with the melting snow pack…
NASA – Researchers Seek ‘Heart’ of Black Hole Mystery
Hubble image of M15 New research, funded by NASA and the University of Tokyo, has shown astronomers may not yet have uncovered the mystery at the heart of one of the Galaxy’s oldest star systems, the globular cluster M15. In…
2007 Rainfall Patterns in United States
The rainfall pattern across the United States during the first eight months of 2007 is a study in contrasts. Drought dominated both coasts, while the Great Plains states saw far more rain than average.
