"This happens to be an opposition where Mars is both closer to the Earth than normal".
During the month of July, Earth and Mars have been getting increasingly closer to one another and will be at their closest point since 2003 beginning this Friday, July 27. Known as "opposition" because we see the planets rise in the east as the sun sets in the west this event gave astronomers a unique chance to capture detailed images of the planets, thanks to their proximity and full illumination from the sun.
On Earth, microorganisms have been found in the subglacial lakes of Antarctica that have existed in isolation from the external Antarctic environment for 35 million years or more and, since numerous 400 subglacial lakes that have been identified so far appear to be hydraulically connected, it is reasonable to conclude that microbial life may exist almost everywhere beneath the Antarctic ice, Clifford said. The past six years of research shows that a salt lake should exist there, 1.5 kilometers underground.
Hubble's view also resolves a hexagonal pattern around Saturn's north pole, a stable and persistent wind feature discovered during the Voyager flyby in 1981. This may be responsible for a string of bright clouds visible near the northern polar region that are the remnants of a disintegrating storm.
While observing the planet Hubble also managed to capture images of six of Saturn's 62 now known moons: Dione, Enceladus, Tethys, Janus, Epimetheus, and Mimas. The moon will appear larger and Mars will be right beneath it, slightly smaller.

The report warns that the "relentless targeting of hyper-partisan views" accross awide range of areas is a threat to democracy. Cambridge Analytica whistle-blower Chris Wylie attends a demonstration in Parliament Square, London , in March.
The search for life on Mars-and the quest to send humans to Mars-just got one step closer.
Earth passes between Mars and the sun every two years and 50 days.
Mars reaches opposition, meaning the Red Planet will roughly align with Earth and the sun. The Kohl telescope at the Martz-Kohl Observatory will be able to magnify surface details as well as the storm. Also, since Mars orbits in a much more elliptical pattern, its distance to the Earth and the sun can vary quite a bit during its orbit.
In an interview with Notimex, Chicana Nuncebay said that on this occasion, the stretch between the "red planet" and the "blue planet" will be close to 57.6 million kilometers, the shortest in the last 100 years. In 2016 the martian atmosphere was clear. Three-dimensional models created from NASA's Viking mission illustrate how the northern hemisphere was tilted away from Earth in 2018.
