This past week on Mars, Perseverance made a pit stop near Overlook Mountain to abrade a rock called Old Faithful Geyser. This target is situated within the Western side of […]
Europa, the second inner Jovian Galilean satellite, is believed to contain a global liquid water ocean covered by an ice shell likely 10s of kilometers thick. The paucity of impact […]
![Pyrite sulfur δ34S values as a function of the natural logarithm of pore water sulfate concentration (r2 = 0.52). Colors correspond to TOC concentration. The solid black line is the line of best fit, with the equation y = −8.4ln([SO4]) − 3.4. The two dashed black lines are parallel to the line of best fit and run 20 ‰ above it and 16 ‰ below it. -- Johns Hopkins University](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/An-Unlikely-Hero-In.png?resize=1200%2C720&ssl=1)
One of Earth’s most consequential bursts of biodiversity—a 30-million-year period of explosive evolutionary changes spawning innumerable new species—may have the most modest of creatures to thank for the vital stage […]
New Curtin-led research has found evidence that fresh water on Earth, which is essential for life, appeared about four billion years ago – five hundred million years earlier than previously […]
Editor’s note: From the paper’s Introduction: “At the time of this writing, PIXL’s adaptive sampling capability has been operating on Mars for over 951 sols (martian days), with over 52 […]
A magma ocean (MO) is thought to be a ubiquitous stage in the early evolution of rocky planets and exoplanets. During the lifetime of the MO, exchanges between the interior […]
To prepare for exploring the Moon during NASA’s Artemis campaign, the agency is conducting a week-long field test in the lunar-like landscape of San Francisco Volcanic Field near Flagstaff, Arizona […]
NASA engineers, managers, and flight directors recently traded their cubicles and conference rooms for an ancient volcanic field in the northern Arizona desert to participate in a field geology course […]
Determining compositions of low-mass exoplanets is essential in understanding their origins. The certainty by which masses and radius are measured affects our ability to discern planets that are rocky or […]
Hadean zircons provide a potential record of Earth’s earliest subduction 4.3 billion years ago. It remains enigmatic how subduction could be initiated so soon after the presumably Moon-forming giant impact […]
