Iceworld Update: Grim Outlook For Antarctica’s Thwaites Glacier

A vast area of the Antarctic Ice Sheet continues to retreat as a UK-US group of scientists reveal new findings about how and when it might suddenly move towards collapse.

Molecular Biosignatures In Planetary Analogue Salts: Implications for Transport of Organics in Sulfate-rich Brines Beyond Earth

Salts formed during evaporation or freezing of brines can potentially incorporate organic matter that can inform about past biological activity. We analysed the lipid fraction preserved within the contemporary Lost […]

Twin Worlds, Divergent Fates: How Obliquity has Differently Shaped Pluto’s and Triton’s Landscapes and Climates

Triton and Pluto are believed to share a common origin, both forming initially in the Kuiper Belt but Triton being later captured by Neptune. Both objects display similar sizes, densities, […]

Astrobiology Fleet Update: Video: Juice’s Lunar-Earth Flyby

On 19–20 August 2024, Juice successfully completed a world-first lunar-Earth flyby, with flight controllers guiding the spacecraft first past the Moon, then past Earth. The gravity of the two changed […]

Locked In A Glacier, Viruses Adapted To Survive Extreme Weather

For decades, the Guliya Glacier, located above 20,000 feet in the far northwestern Tibetan Plateau, has been one of the richest archives available to scientists to investigate large-scale paleoclimate shifts. […]

Three-stage Formation of Cap Carbonates after Marinoan Snowball Glaciation Consistent with Depositional Timescales and Geochemistry

At least two global “Snowball Earth” glaciations occurred during the Neoproterozoic Era (1000-538.8 million years ago). Post-glacial surface environments during this time are recorded in cap carbonates: layers of limestone […]
