Mars may once have had a much larger moon
  • Recent studies suggest that Mars may have once possessed a much larger moon, which could have influenced the planet's hydrological features, including lakes and seas, through its gravitational pull. Currently, Mars is orbited by two small moons, which may be remnants of this larger celestial body.
  • Understanding the historical presence of a larger moon around Mars is significant as it could reshape current knowledge about the planet's geological and hydrological history, providing insights into its past environments and potential habitability.
  • This revelation aligns with ongoing research into Mars' climatic history, including findings of bleached rocks that indicate past tropical conditions, suggesting a complex interplay between celestial bodies and planetary evolution that may have implications for understanding other celestial bodies in the solar system.

How Mars' ancient lakes grew shields of ice to stay warm as the Red Planet froze
NeutralScience
Recent findings suggest that ancient lakes on Mars developed ice shields to maintain warmth, potentially explaining how liquid water persisted on the planet despite a colder climate. This discovery sheds light on Mars' hydrological history and its capacity to support water in various forms.
T. rex took 40 years to become fully grown
NeutralScience
An analysis of growth rings in the leg bones of 17 Tyrannosaurus rex individuals indicates that these dinosaurs took approximately 40 years to reach full maturity, suggesting a slower growth rate than previously believed. This finding contributes to the understanding that T. rex may not represent a single species but rather a more complex evolutionary lineage.
