00:00:00,060 --> 00:00:04,140
When the sun goes down, the lights of human activity shine bright. 

2
00:00:04,140 --> 00:00:08,320


3
00:00:08,320 --> 00:00:12,420
NASA scientists have just released the first new global map of Earth at night since 2012.

4
00:00:12,420 --> 00:00:16,590


5
00:00:16,590 --> 00:00:20,700
The VIIRS instrument on board the NASA-NOAA Suomi NPP satellite captures a high-resolution view of...

6
00:00:20,700 --> 00:00:24,950
city lights...

7
00:00:24,950 --> 00:00:29,030


8
00:00:29,030 --> 00:00:33,040


9
00:00:33,040 --> 00:00:37,080
boats on the water...

10
00:00:37,080 --> 00:00:41,220
how people follow geography...

11
00:00:41,220 --> 00:00:45,250
population patterns...

12
00:00:45,250 --> 00:00:49,460


13
00:00:49,460 --> 00:00:53,530


14
00:00:53,530 --> 00:00:57,650
The new global map of night lights is a composite image

15
00:00:57,650 --> 00:01:01,980


16
00:01:01,980 --> 00:01:06,150
but later this year NASA scientists will release the first daily night lights data

17
00:01:06,150 --> 00:01:10,190


18
00:01:10,190 --> 00:01:14,310


19
00:01:14,310 --> 00:01:23,264
allowing scientists to better aid disaster response and study energy use.
