NEW ORLEANS — NASA’s Perseverance Mars rover is continuing its mission to collect samples despite uncertainty about how, when or even if those samples will be returned to Earth. At
Plot of the Habitable Zone (HZ) completeness as a function of host star luminosity (in units of Solar luminosity) and distance (in parsecs). Here the AYO results are on the
NASA/Zena Cardman In this Oct. 20, 2025, photo, tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the
Imagine a year filled with the breathtaking beauty of the universe, captured through the lens of humanity’s most advanced telescope—the James Webb Space Telescope. This 2026 Astronomy Wall Calendar invites

Artistic representation of the collision of two planetesimals in the circumstellar disc of the star Fomalhaut. Credit Thomas Müller (MPIA) Young star systems are a place of violent collisions. Rocks,
Comparison result between the DBSCAN algorithm and the KNN algorithm for residual RFI mitigation. Data points marked in red represent signals identified and removed as residual RFI, while those in
The transmission spectrum of TOI-732 c in the NIR. We show the spectrum and retrieved model fits for the one-offset retrieval, as discussed in Section 3.3. This model includes the
Schematic loosely sketching the parameter space accessible using the astrometric technique as compared to the transit methods of exomoon detection in the context of the moon survival rate as a
