NASA gives Hurricane Fernanda a close-up

Hurricane Fernanda is moving through the deep tropics and there's nothing in its way to prevent it from becoming a major hurricane. NASA's Terra satellite took a closer look at the strengthening storm.
On July 13 at 1:30 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a close-up visible-light image of Hurricane Fernanda as it continued moving west through the Eastern Pacific Ocean. The visible MODIS image showed a concentration of strong thunderstorms wrapped around the low-level center and a large, thick band of thunderstorms spiraling into the center from the west. Although the image did not reveal an eye, a ragged eye formed later in the day and was seen in satellite imagery using infrared light.
By July 14 at 5 a.m. EDT (0900 UTC), the center of Hurricane Fernanda was located near 11.0 degrees north latitude and 117.9 degrees west longitude. That's about 975 miles (1,570 km) southwest of the southern tip of Baja California, Mexico. Fernanda's maximum sustained winds had increased to 100 mph (155 kph). Fernanda was moving toward the west near 12 mph (19 kph) and this motion is expected to continue over the next couple of days

Evidence of Ancient Lake on Mars

NASA's senior rover, is currently examining the edge of a crater on the red planet that may once have been a lake of liquid water and found rocks at the edge of Endeavour Crater that were either transported by a flood or eroded in place by wind.
The Opportunity mission has been investigating sites on and near the western rim of Endeavour Crater since 2011. The crater is about 22 km across.

Antarctic Sea Ice Loss

As per a new study, a series of unprecedented storms over the Southern Ocean likely caused the most dramatic decline in Antarctic sea ice seen to date.
Antarctic sea ice, frozen ocean water that rings the southernmost continent, has grown over the past few decades but declined sharply in late 2016. By March of 2017, the end of the Southern Hemisphere’s summer – Antarctic sea ice had reached its lowest area since records began in 1978.

Earth Warming to Tipping Point

A monthly analysis of global temperatures by NASA scientists has revealed that May 2017 was the second warmest May in 137 years of modern record-keeping, indicating that our climate is changing and quickly.
The monthly analysis by the scientists at NASA's Goddard Institute for Space Studies (GISS) in New York is assembled from publicly available data acquired by about 6,300 meteorological stations around the world, ship-and buoy-based instruments measuring sea surface temperature, and Antarctic research stations.
The modern global temperature record began around 1880 because previous observations did not cover enough of the planet.
