The moon is more geologically complex than previously thought, scientists report Sept. 17 in two papers published in the journal Science.

Their conclusion is based on data from the Diviner Lunar Radiometer Experiment aboard NASA's Lunar Reconnaissance Orbiter (LRO), an unmanned mission to comprehensively map the entire moon. The spacecraft orbits some 31 miles above the moon's surface.

NASA's Aqua and TRMM satellites have been watching Karl's clouds and rainfall as he moved across Mexico's Yucatan Peninsula and into the Gulf of Mexico today, powering up into a hurricane.

Hurricane Igor is a monster hurricane in terms of strength and size. To get a perspective on its size, it is the same distance from one end of the storm to the other as it is from Boston, Mass. to Richmond, Va., some 550 miles. That's a 10-hour drive from one end to the other, and NASA satellites captured that entire distance in one image.

Hurricane Julia intensified rapidly overnight and is now a Category 4 hurricane on the Saffir-Simpson Scale and NASA's Aqua, Terra and TRMM satellites captured clues as they passed over her from space.

Tests of a potential vaccine against "Ich" — the dreaded "white-spot" disease that plagues fish in commercial fish farms, public aquariums, pet fish retail outlets, and home aquariums — are raising hopes for finally controlling the disease, scientists reported at the 240th National Meeting of the American Chemical Society.

NASA's Aqua satellite captured the birth of Tropical Storm Karl on Sept. 14 as it passed overhead at 3:05 p.m. EDT in the Caribbean. This morning, Karl made landfall in the east coast of the Yucatan Peninsula, Mexico.

An astronomer may have caught a cannibalistic star in the act of devouring a companion and making a second generation of exoplanets from the resulting orbiting disk.

GOES-13 captured a look at System 92L this morning as it continues moving through the central Caribbean, and it's looking more and more like a tropical depression.

Evidence that a star has recently engulfed a companion star or a giant planet has been found using NASA's Chandra X-ray Observatory. The likely existence of such a "cannibal" star provides new insight into how stars and the planets around them may interact as they age.

MIAMI -- September 14, 2010 --There is a significant disparity between knowledge and attitudes on the dangers of skin cancer among male and female medical students in Florida according to a new study by a joint team of researchers from Ben-Gurion University of the Negev and the University of Miami Miller School of Medicine. The study was published in the American Medical Association's Archives of Dermatology.

NASA Satellites have noticed two distinct features in Igor that both indicate how powerful he has become, icy cold, high cloud tops and very heavy rainfall. NASA's Aqua and TRMM satellites have provided that insight to forecasters who are predicting Igor's next move as a powerful Category 4 Hurricane.
