On 18 March 2013, NASA reported evidence from instruments on the Curiosity rover of mineral hydration, likely hydrated calcium sulfate, in several rock samples including the broken fragments of "Tintina" rock and "Sutton Inlier" rock as well as in veins and nodules in other rocks like "Knorr" rock and "Wernicke" rock. The amount of Martian deuterium is eight times the amount on Earth, suggesting that ancient Mars had significantly higher levels of water. Other geological features, such as deltas and alluvial fans preserved in craters, are further evidence for warmer, wetter conditions at an interval or intervals in earlier Mars history. Observers with a very low southwestern horizon might be able to see Fomalhaut, ranked 18th, in Piscis Austrinus the Southern Fish.

m. local time at month's end, but the earlier sunsets of autumn will deliver several hours of excellent evening viewing all month long. Indigenous groups have their own names for the full moons, which lit the way of the hunter or traveler at night before modern conveniences like flashlights. Uranus' small, blue-green dot will also appear slightly larger in telescopes for about a week centered on opposition night. When the telescope became available, the diurnal parallax of Mars was again measured in an effort to determine the Sun-Earth distance.From Brahe's observations of Mars, Kepler deduced that the planet orbited the Sun not in a circle, but in an ellipse.

Therefore, their closest approaches, the inferior conjunctions, are the second closest for Earth after those with Venus, and the closest for Mars to any other planet.Structural analysis of the Valles Marineris fault zone: Possible evidence for large-scale strike-slip faulting on Mars".

Night sky, October 2023: What you can see tonight [maps]

Regions of low albedo suggest concentrations of plagioclase feldspar, with northern low albedo regions displaying higher than normal concentrations of sheet silicates and high-silicon glass. Along craters and canyon walls, there are thousands of features that appear similar to terrestrial gullies. Impact glass, formed by the impact of meteors, which on Earth can preserve signs of life, has also been found on the surface of the impact craters on Mars. Both the Mars Reconnaissance Orbiter and Mars Express continued exploring with new instruments and supporting lander missions.Because Mars lacks a global magnetic field, the types and distribution of auroras there differ from those on Earth; [126] rather than being mostly restricted to polar regions as is the case on Earth, a Martian aurora can encompass the planet. The high altitude, extreme cold, dry air and new sensations can overwhelm the human brain as it adjusts to the new environment. In September 2015, NASA announced that they had found strong evidence of hydrated brine flows in recurring slope lineae, based on spectrometer readings of the darkened areas of slopes. By the period of the Neo-Babylonian Empire, the Babylonian astronomers were making regular records of the positions of the planets and systematic observations of their behavior. Images from the Thermal Emission Imaging System (THEMIS) aboard NASA's Mars Odyssey orbiter have revealed seven possible cave entrances on the flanks of the volcano Arsia Mons.

The planet will travel eastward from Libra, through Scorpius and southern Ophiuchus before entering Sagittarius on Nov. When large sunspots develop on the sun, they can be seen without a telescope — as long as you use proper solar filters, such as eclipse glasses. Mars is scarred by a number of impact craters: a total of 43,000 craters with a diameter of 5 kilometres (3. A third possibility for their origin as satellites of Mars is the involvement of a third body or a type of impact disruption.Mars is usually close enough for particularly good viewing once or twice at 15-year or 17-year intervals. The November Full Moon, traditionally known as the Beaver Moon or Frost Moon, always shines within or near the stars of Taurus and Aries. The largest exposed crater is Hellas, which is 2,300 kilometres (1,400mi) wide and 7,000 metres (23,000ft) deep, and is a light albedo feature clearly visible from Earth. Its local relief, from the foot of the cliffs which form its northwest margin to its peak, is over 21km (13mi), [85] a little over twice the height of Mauna Kea as measured from its base on the ocean floor. The canali were independently observed by other astronomers, like Henri Joseph Perrotin and Louis Thollon in Nice, using one of the largest telescopes of that time.
