The climate throughout Mars’ early history has long been debated – was the Red Planet warm and wet, or cold and icy? New research published in Icarus provides evidence for the latter.

Research led by the University of Sydney shows that under warm water events the nutritional balance of fish and squid changes and is of lower quality, while under cold water events it is of higher quality.

When NASA's Aqua satellite passed over Aletta in the Eastern Pacific Ocean it had just become the first hurricane of the season. Infrared imagery showed that Aletta appeared more organized. The National Hurricane Center noted that Aletta could become a Category 4 hurricane later on June 8.

While avoiding the worst dangers of climate change will likely require sucking carbon dioxide out of the sky, prominent scientists have long dismissed such technologies as far too expensive.

The number of drug-resistant malaria cases is increasing — posing a serious world health threat.

A computer program that uses artificial intelligence to sort through historical meteorological data is being developed to help predict where and when future forest fires will take place so they can be prevented.

Changes in diet have been proposed as a way to reduce carbon emissions from the food system. But there has been little research on the affordability and feasibility of low-carbon food choices in the U.S. and how these choices could affect diet and climate change.

Tropical Cyclone Ewiniar made landfall on mainland China and as the center of circulation has moved back into the South China Sea and reorganized, NASA-NOAA's Suomi NPP provided a look at the storm.

Spiral galaxies such as the Milky Way have discs which are really thin, in which the major fraction of their stars are found. These discs are limited in size, so that beyond certain radius there are very few stars left.

Tropical Storm Aletta is spinning more than 440 miles off the southwestern coast of Mexico and using satellite data, NASA peered into the storm to uncover where the heaviest rain was falling.
