After five years, NASA has unveiled new fascinating images of our planet captured from space. In 2012 was the last time when NASA shared a global map of planet Earth during the night time. Now, scientists have amazed us with the new breathtaking captures. Even if many recent discoveries regarding distant planet and possible alien life appeared to be more interesting for us, we should not forget the beauty of our planet.
NASA has released some fascinating images of Earth during nighttime
The immensity of space, though beautiful, may sometimes be scary and we remember that there is no place like home. We are so preoccupied about discovering new planets and new solar systems that we forget about the wonderful planet we live on. NASA has analyzed how light is emitted, distributed and reflected by atmospheric, land and ocean surfaces.
The main challenge when capturing images during the nighttime is to account for the moon phases which determines a light variation when it comes to the amount of sunlight shining on our planet. NASA has named the new set of images “Black Marble,” being the counterpart of the “Blue Marble” which were captured back on December 7, 1972, by the Apollo 17 crew.
The imaging project could help scientists track cyclical modifications related to human activities
Mike Massimino, who is a former astronaut, explained the astonishing pictures. The advancement of technology helped specialists take these fascinating images which unveil the areas that are among the most populated ones via the amount of light seen in one place during the nighttime. For instance, these lights indicate that people in Australia inhabit the areas along the coast.
Some countries appear to be less illuminated than America, being a little darker than the rest of affluent countries. Massimino stated that America is brighter than a Christmas tree, especially when it comes to the West and East coasts. During the nighttime, space is an incredible wonderland which makes all humans feel small compared to its vastness.
The NASA team, which is now equipped with more precise nighttime environmental products, is bound to transform this process into an automated one for people to see nighttime imagery within a certain timespan. Thus, this method might be helpful for disaster response and limited-term weather forecasting.
Dr. Miguel Roman, a scientist at NASA Goddard Space Flight Center in Greenbelt, Maryland, argued that they could use this imaging project to monitor cyclical modifications that occur due to human activities, like season migrations or holiday lighting. They are also bound to track gradual changes which appear as the result of urbanization, economic changes, electrification, and out-migration.
