Scientists from NASA have created a video of the Earth, in which it is captured from the perspective that hypothetical aliens would see from space
The American Deep Impact spacecraft, sent towards the comets, has created a series of unique images of the Earth around which the Moon orbits.
The planet was captured from a distance of about fifty million kilometers, showing it for the first time in dynamics with sufficient clarity that makes it possible to distinguish oceans and continents on Earth, and huge craters on the surface of a natural satellite, according to Dni.ru.
Based on these photographs, which were taken at 15-minute intervals during one revolution of the planet around its axis, NASA scientists have created a video showing the celestial body from a rare angle. Only aliens from outer space or astronauts who went to the depths of the solar system can see the Earth in this form.
The resulting film was published by NASA on its website. The same film is posted on the Yotube portal.
In the video, the Earth makes a full revolution on its axis. During the recording, the Moon passes between the camera and the Earth. The mini-movie was created from separate static photographs taken by the Deep Impact ship on May 28 and 29, 2008, with a frequency of one shot every 15 minutes.
At the time of filming, "Deep Impact" was at a distance of about 49 million kilometers from Earth.
The resulting video was created not only for popular science purposes. Scientists hope the video will help them find Earth-like planets. The guideline for researchers should be the radiation of the Sun, which is reflected from the Earth's surface. By studying the changes in its brightness as it “passes” over oceans, land or clouds, scientists will be able to judge the existence of Earth-like planets by analyzing the light that came from space.

The ship "Deep Impact", which took the photographs for the film, was launched on January 12, 2005. Its tasks included a "meeting" with the comet Tempel-1 and launching a copper blank to it on July 4th, 2005. After this goal was achieved, although not completely, NASA extended the "Deep Impact" project until November 4, 2010, when the ship should meet with comet Hartley II. The new mission was named "EPOXI", which combines two abbreviations, each of which reflects one of the mission objectives. The first part of the word - "EPO" comes from Extrasolar Planet Observations and Characterization - EPOCh (search and characterization of planets outside the solar system). The second - "XI" - from the abbreviation DIXI (Deep Impact eXtended Investigation - extended research with the help of the ship "Deep Impact").
