Fighting to the end
After wreaking havoc on the East Coast, Hurricane Sandy was spotted by a NASA satellite as it weakened into a remnant low pressure system over Pennsylvania on Halloween.
Sandy was a Category 1 hurricane as it approached the coast of New Jersey on Oct. 29, packing winds of up to 90 mph (145 kph) that spread over a vast distance. The hurricane then became a post-tropical cyclone and merged with a cold front to become a hybrid nor'easter.

A series of satellite photos of Hurricane Sandy have captured eye-popping views of the frightening storm from space, showing the tempest in relation to the entire planet Earth, as well as its appearance at night.
The new satellite views of Hurricane Sandy were snapped Sunday (Oct. 28) by the GOES-13 weather satellite and the powerful Suomi NPP Earth-watching satellite. Both satellites are used by NASA and the National Oceanic and Atmospheric Administration to monitor Earth's weather.

Under cover of night
All of NASA's electronic eyes in space seem trained on Hurricane Sandy's march across the Northeast and Mid-Atlantic.
NOAA's GOES-13 satellite captured a visible image of post-tropical cyclone Sandy rolling overland this morning (Oct. 30) at 6:02 a.m. EDT. The powerful storm lost its hurricane status on Monday as its source of power shifted from warm ocean waters and air to interacting with a cold front along the coastline.

In the immediate aftermath of Hurricane Sandy, more than 8 million people were thought to be without power. Some 90 percent of Long Island lost power, as well as numerous communities in New Jersey and all of Lower Manhattan ?which created strange views of the island's iconic skyline from neighboring boroughs and New Jersey.
