In this episode of SpaceTime, we dive into groundbreaking discoveries on Mars, the intriguing atmosphere of Makemake, and the awe-inspiring total lunar eclipse that captivated millions.
Potential Biosignatures on Mars
NASA scientists have revealed that samples collected by the Perseverance rover from Jezero Crater may hold the best chance yet of uncovering evidence of past microbial life. The samples, taken from the rock formation known as Chiava Falls, exhibit characteristics that could indicate potential biosignatures. These findings suggest that Mars may have been habitable for longer than previously thought, challenging earlier assumptions about the planet's history.
Atmosphere Discovered on Makemake
In a remarkable discovery, astronomers have detected indications of a methane gas atmosphere on the distant dwarf planet Makemake. This finding, made using NASA's Webb Space Telescope, suggests the presence of a tenuous atmosphere or possibly cryovolcanic activity. Makemake, which resides in the Kuiper Belt, is now only the second known trans-Neptunian object, after Pluto, to have confirmed gaseous presence, revealing its dynamic nature and potential for active geology.
Total Lunar Eclipse
A stunning total lunar eclipse has mesmerised observers across Australia, Europe, Africa, and Asia. This celestial event transformed the full moon into a blood-red spectacle as Earth’s shadow obscured it. The eclipse lasted over five hours, showcasing the beauty of orbital mechanics and providing a thrilling experience for stargazers.
