NASA sees Tropical Storm Karina get a boost

NASA's TRMM satellite saw Tropical Storm Karina get a boost on August 22 in the form of some moderate rainfall and towering thunderstorms in the center of the storm.

NASA sees massive Tropical Storm Lowell close enough to trouble Baja California

NASA sees massive Tropical Storm Lowell close enough to trouble Baja California

Although Tropical Storm Lowell is not over land the storm is large enough to cause strong ocean swells in Baja California. NASA's Terra satellite passed over Lowell and captured an image that shows how it dwarfed Tropical Storm Karina.

The National Hurricane Center noted that swells generated by Lowell will affect the west coast of the Baja California, Mexico, peninsula and portions of the coast of southern California through the weekend of August 23 and 24. These swells are likely to cause life-threatening surf and rip current conditions.

Powerful thunderstorms in newborn Tropical Storm Marie were seen stretching toward the top of the troposphere in infrared imagery from NASA's Aqua satellite.

Electric sparks may alter evolution of lunar soil

Electric sparks may alter evolution of lunar soil

The moon appears to be a tranquil place, but modeling done by University of New Hampshire (UNH) and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system.

Cause of global warming hiatus found deep in the Atlantic Ocean

Cause of global warming hiatus found deep in the Atlantic Ocean

Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. At first this was a blip, then a trend, then a puzzle for the climate science community.

Lowell is now a large hurricane in the Eastern Pacific and NASA's Aqua and Terra satellites double-teamed it to provide infrared and radar data to scientists. Lowell strengthened into a hurricane during the morning hours of August 21.

Despite being the eleventh tropical cyclone of the Eastern Pacific Ocean Hurricane Season, Karina looked like a giant number nine from NASA's Aqua satellite.

Spectacular supernova's mysteries revealed

New research by a team of UK and European-based astronomers is helping to solve the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year.

The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance at the University of London Observatory. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve.

Toothpaste fluorine formed from our sun's dead ancestors

The fluorine that is found in products such as toothpaste was likely formed billions of years ago in now dead stars of the same type as our sun. This has been shown by astronomers at Lund University in Sweden, together with colleagues from Ireland and the USA.
