This is the perfect time to observe Jupiter.

Mars formed by the action of liquid water

Discovered in 2005, the clays in the southern hemisphere of Mars are often considered as a proof of the survival of liquid water on the Red Planet at a very early period of between 4.5 and 4 billion years. But the work of a Franco-American team led by researchers at the Institute of Chemistry of materials and environments Poitiers (CNRS / University de Poitiers) [1] questioned this interpretation. In an article to be published on September 9 on the website of the journal Nature Geosciences, they show that these clays are likely to be of magmatic origin. The many similarities between the Martian clays and those of volcanic origin collected on the Murrow atoll support their hypothesis.

The Odd Couple of galaxies in space travel

Two very different galaxies drift through space at the same time in this image taken by the Hubble Space Telescope. The curious pair of galaxies Arp 116 is called. Arp 116 is composed of a giant elliptical galaxy known as Messier 60 (or M60) and a much smaller spiral galaxy, NGC 4647. The spiral galaxy NGC 4647 light blue is about two-thirds of M60 in size and much lower mass - about the size of our galaxy, the Milky Way.
