For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today.
K2-18b, a temperate sub-Neptune, has garnered significant attention due to claims of possible biosignatures in its atmosphere. Low-confidence detections of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) have sparked considerable […]
By fitting its sunshield and solar panels, engineers have completed the construction of Plato, the European Space Agency’s mission to discover Earth-like exoplanets. Plato is on track for the final […]
Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of […]
![(a) Top panel shows [Eu/α] independent of the temperature bias as a function of [α/H]. Small orange triangles represent data from DM and small green triangles represent data from BB. The cross matched sample of 68 stars described in Section 3.1 is shown in big red squares. Stars from the solar twins analysis by Spina et al. (2018), Bedell et al. (2018) are shown as big blue circles. A black star is used to represent the solar abundance value. The red dashed line at [Eu/α] = 0.06 represents the critical value for an extended dynamo failure given by the model from Nimmo et al. (2020). Outliers in [Eu/H] abundances discussed in Section 6.2 are outlined in black. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/Distribution-of-Europium.png?resize=1200%2C711&ssl=1)
The energy provided in the radioactive decay of thorium (Th) and uranium (U) isotopes, embedded in planetary mantles, sustains geodynamics important for surface habitability such as the generation of a […]
Jezero Crater on Mars is a critical site for investigating ancient aqueous environments due to its preserved delta and lacustrine features.
Giant impacts, the collisions between planetary embryos, play a crucial role in sculpting the planets and their orbital architectures.
Enceladus is among the most intriguing bodies in the solar system due to its astrobiological potential.
The search for life beyond Earth has long been guided by two dominant paradigms: astrobiology, which seeks environments capable of supporting life as we know it, and planetary engineering, which […]
Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are […]
