NASA finds a tiny tropical storm Kiko

(NASA/Goddard Space Flight Center) NASA’s Terra satellite is one in a fleet of NASA satellites that provide data for research. Terra captured an image of Tropical Storm Kiko in the Eastern Pacific Ocean which showed the extent of the small storm.

NASA estimates Tropical Depression Imelda’s huge Texas rainfall

(NASA/Goddard Space Flight Center) Northeastern Texas has borne the brunt of Tropical Depression Imelda’s heavy rainfall and NASA estimated that rainfall with an algorithm that incorporates data from satellites and observations.

Are Saturn’s rings young or old?

Cassini data suggested that Saturn’s rings were only 10 to 100 million years old. A new study suggests that a “ring rain” onto Saturn makes the rings look younger than they really are, and that in fact Saturn’s rings date back billions of years.

Low sea-ice cover in the Arctic

(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by sea ice any more, according to researchers from the Alfred Wegener Institute and the University of Bremen.

Mako shark tracking off west coast reveals ‘impressive’ memory and navigation

(NOAA Fisheries West Coast Region) The largest effort ever to tag and track shortfin mako sharks off the West Coast has found that they can travel nearly 12,000 miles in a year. The sharks range far offshore, but regularly return to productive waters off Southern California, an important feeding and nursery area for the species.

Satellite data record shows climate change’s impact on fires

(NASA/Goddard Space Flight Center) While every fire needs a spark to ignite and fuel to burn, it’s the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn.

Have astronomers found a hyper-volcanic exomoon?

Astronomers have found evidence for a possible exomoon orbiting a gas giant planet 550 light-years away. If they’re interpreting the evidence correctly, this moon would be a place of destruction, even more volcanically active than Jupiter’s famous volcanic moon, Io.
