NASA Media Preview Of The Europa Clipper Astrobiology Mission
NASA will host a news conference at 11 a.m. EDT Tuesday, Sept. 17, at the agency’s Jet Propulsion Laboratory in Southern California to discuss the upcoming Europa Clipper mission to […]
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, […]
A Gigantic Asteroid Impact Shifted The Axis Of Ganymede
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher realized that the Solar System’s biggest moon’s axis has shifted as a result […]
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 […]
Astrobiology Fleet Update: Video: Europa Clipper’s Super-Size Solar Arrays
NASA’s Europa Clipper spacecraft recently got outfitted with a set of enormous solar arrays at the agency’s Kennedy Space Center in Florida. Each measuring about 46½ feet (14.2 meters) long […]
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 […]
The Evolution Of A Young Ocean Within Mimas
The fractured, young surfaces on confirmed ocean worlds such as Europa and Enceladus suggest that ocean-bearing moons with relatively thin overlying ice shells should be easy to identify. Hence, the […]
