Pareidolia (/ ˌ p ær ɪ ˈ d oʊ l i ə, ˌ p ɛər-/; [1] also US: / ˌ p ɛər aɪ-/) [2] is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one detects an object, pattern, or ...
Earth-based telescopes equipped with charge-coupled devices can produce useful images of Mars, allowing for regular monitoring of the planet's weather during oppositions. [ 93 ] X-ray emission from Mars was first observed by astronomers in 2001 using the Chandra X-ray Observatory , and in 2003 it was shown to have two components.
An 1877 map of Mars by Giovanni Schiaparelli. North is at the top of this map. In most maps of Mars drawn before space exploration the convention among astronomers was to put south at the top because the telescopic image of a planet is inverted. The first detailed observations of Mars were from ground-based telescopes.
This week, explore the technology that could allow humans to live on Mars, uncover the truth of a Neanderthal flower burial, see a leggy birdlike dinosaur, and more. New mosaic of Mars could ...
Microscopic images of the soil taken by Opportunity revealed small spherically shaped granules. They were first seen on pictures taken on Sol 10, right after the rover drove from the lander onto martian soil. When Opportunity dug her first trench (Sol 23), pictures of the lower layers showed similar round spherules. But this time they had a ...
Finding Mars is easy this week, as it shines brightly in the eastern sky, offering observers a chance to see a stunning view of Mars. While observing Mars, look to the east, and remember to also ...
A City on Mars is a counterbalance to the growing optimism over space exploration.
The maximum angular separation of the Earth and Moon varies considerably according to the relative distance between the Earth and Mars: it is about 25′ when Earth is closest to Mars (near inferior conjunction) but only about 3.5′ when the Earth is farthest from Mars (near superior conjunction). For comparison, the apparent diameter of the ...
