Mars' climate is a tale of two planets. Evidence suggests a warm and wet early Mars. A thicker atmosphere, likely rich in carbon dioxide, trapped heat and allowed liquid water to flow, carving river valleys and potentially vast oceans. This era may have been fueled by volcanic eruptions or a strongeRead more
Mars’ climate is a tale of two planets. Evidence suggests a warm and wet early Mars. A thicker atmosphere, likely rich in carbon dioxide, trapped heat and allowed liquid water to flow, carving river valleys and potentially vast oceans. This era may have been fueled by volcanic eruptions or a stronger sun.
Over billions of years, Mars lost its magnetic field, leaving it vulnerable to solar wind stripping away the atmosphere. The planet turned frigid and dry, with remaining water locked as ice caps or underground. The thin atmosphere now allows dramatic temperature swings and dust storms.
The sculpted surface reflects this history. Cratered plains hint at heavy bombardment early on. Dried-up riverbeds and lakebeds are ghostly reminders of a watery past. Volcanic giants like Olympus Mons tower over the landscape, a testament to past activity that may have influenced Mars’ climate.

Early astronomy instruments and methods were greatly influenced by astrology. Astronomical theories and the study of celestial events were closely related in ancient societies like Babylon, Egypt, and Greece. More precise observational instruments were required because astrologers aimed to forecast earthly events by comprehending the movements of planets and stars.
To anticipate eclipses and planetary placements, for example, the Babylonians developed early astronomical tables and improved observing tools such as the gnomon, which was the ancestor of the current sundial. Similarly, astrological considerations had a significant influence on the work of Greek astronomers like Hipparchus, who is often regarded as a pioneer in the creation of trigonometry. The necessity to comprehend celestial body placements for astrological forecasts drove him to create star catalogs and systems for predicting celestial events.
All things considered, astrology served as the inspiration and the basic structure for the creation of astronomical instruments and methods. As a result of the quest for astrological information, observational astronomy advanced, setting the stage for the ultimate separation of astronomy and astrology and the development of contemporary scientific techniques.
