Astrobiology, while traditionally focused on understanding the origin of life on Earth and the potential for life elsewhere, offers powerful tools and insights for addressing urgent challenges on our planet.
Future planetary exploration missions will rely heavily on efficient human–robot interaction to ensure astronaut safety and maximize scientific return.
The detection of viable life is a key objective for both in situ astrobiological experiments on extraterrestrial bodies, and for planetary protection protocols on Earth following sample return.
![Maximum predicted emission frequency and radio flux density for known exoplanets (triangle symbols; data from [8]). The uncertainties on the predictions are estimated to one order of magnitude for the flux density and a factor of 2-3 for the emission frequency12. The sensitivities for the ground-based (UTR-2, LOFAR, NenuFAR, SKA-Low, VLA, GMRT) and space-based (FARSIDE, LCRT, FARVIEW ) radio telescopes are labeled (for 10 min of integration time and a bandwidth of 24 MHz). The FARVIEW and LCRT sensitivity curves are taken from [19] and [2], respectively. The LuSEE-Night sensitivity curve is averaged over the entire two-year mission and includes post-processing using a LombScargle periodogram (see text for details). The possible detection of τ Boo b from LOFAR23 is shown as a red star. This figure is adapted from [9]. -- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/Studying-Exoplanets-in.png?resize=1200%2C720&ssl=1)
Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently.
![Comparison of elemental abundances from the literature and this work (filled circles) for the same stars. The y-axis shows the difference in abundance, [X/H]literature – [X/H]this work, plotted against the Tc of each element on the x-axis. Potassium (K) is excluded as it was not reported in the literature. The open squares and downward triangles show a direct comparison of abundances measured from HARPS and MIKE spectra using the same spectral lines and analysis methods applied in this study. The differences reflect both instrumental systematics and manual measurement variability between HARPS and MIKE. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/Planets-Around-Solar-TwinsAnalogs.png?resize=1200%2C720&ssl=1)
Context. Previous studies have suggested that the Sun is relatively depleted in refractory elements compared to other solar twins or analogs, potentially as a result of planet formation. However, such […]
Ancient Antarctic microbial mats harbour viable bacteria that have been exposed to extreme cold and arid conditions for hundreds of years.
The ongoing exploration of planets such as Mars is producing a wealth of data to define habitable environments beyond the Earth.
Understanding the mechanisms of protein preservation in extreme environments is essential for identifying potential molecular biosignatures on Mars.
However, traditional atmospheric retrieval frameworks are too computationally intensive to explore the high-dimensional parameter spaces such missions will generate.
Gossans are formed through the oxidation of sulfide ore deposits by fluids, such as meteoric water or hydrothermal solutions, leading to locally acidic conditions.
