Giovanni Schiaparelli’s 1878 map of Mars has a distribution of features interpreted as land (white) and sea (blue). Many of the names Schiaparelli gave to locations on Mars are still

Figure 3b shows key word frequency over time. Like co-occurrence network map, the term Extremophiles with the highest increase, reaches a cumulative frequency by 2023. As the second most frequently

NASA’s Curiosity Mars rover captured this view looking back down at the floor of Gale Crater from its location on Mount Sharp on Feb. 7, 2025, the 4,447th Martian day,

Side-by-side comparison of TOI (left) and KOI (right) radius vs orbital period. The red dashed line marks the 14-day orbital period. TOI detected more giant planets with shorter orbital periods,

In the location map, dashed lines represent the magnetic anomaly lineations. Note the scale change in the N/K and N/Na ratios marked by the dashed lines. — Nature University of
