For this summer 2018, the planets Mars and Saturn are located relatively close to the Earth and so astronomers took the opportunity to observe them with a greater detail, through the space telescope Hubble from the NASA and from the European Space Agency where they obtained images of both planets
. Earth, Saturn could be seen on June 27 and March on July 27. During an opposition, astronomers can see more detailed planet features when a planet is completely illuminated by the Sun, seen from Earth, points out agency N + 1.
On June 6, a month before Saturn's opposition, Hubble was used to observe the planet. At that time, it was about 1400 million kilometers from the Earth, but it was enough for images near its maximum slope to Earth to take a look at the rings and interstices between them.
captured images of six of his 62 known moons: Dione Enceladus Tethys Janus Epimetheus and Mimas . According to scientists, a disastrous little satellite like these has disintegrated 200 million years ago to form Saturn 's ring system.
For the portrait of the planet Mars, the telescope was placed on July 18 as Mars reached its maximum approach to the Earth. In 2018, the planet was approaching 57.6 million kilometers from Earth, the closest since 2003, when it was closer than at any other time in nearly 60,000 years, to 55.7 million kilometers.
In this new image dominates a gigantic sandstorm that envelops the entire planet. The white polar caps are still visible, but these features are lessened by dust in the atmosphere.
Astronomers, who compared these new images of Mars and Saturn with older data from Hubble and other telescopes, can study how cloud patterns and large-scale structures on the planet can be compared. other planets in the solar system change over time.
