Organic carbon detected in Bright Angel rock formation on Mars
Organic carbon — the fundamental building block of life — has been unambiguously confirmed in rocks from Mars' Bright Angel formation, according to a new study published in Science Advances. The discovery builds on a potential biosignature flagged by NASA's Perseverance rover in September 2025, providing a more detailed chemical picture of the organic matter present. While the findings do not confirm life existed on Mars, they mark a significant step in understanding the planet's potential to have supported it.

A NASA satellite caught a giant tsunami doing something no one expected
A magnitude 8.8 earthquake off Kamchatka sent a tsunami racing across the Pacific, and for the first time, scientists had a NASA satellite in position to watch it unfold in real time. What they saw defied expectations: the waves behaved differently than established models predicted, and the data pointed to a far larger seismic rupture than initially estimated. The findings stand to reshape how researchers model and forecast tsunamis going forward.

The universe should look the same in all directions at large scales, but DESI data suggest otherwise
The cosmological principle — the bedrock assumption that the universe is uniform in all directions at large scales — may be wrong, according to new research published in Nature. Analyzing DESI's landmark survey of 47 million galaxies spanning 11 billion light-years, astronomers Francesco Sylos Labini and Marco Galoppo found evidence of large-scale directional variation in the universe's structure. If confirmed, the finding would force a fundamental rethink of modern cosmology's foundational framework.

Euclid mission view of Milky Way's heart previews upcoming survey by NASA's Roman
The European Space Agency's Euclid telescope has captured a sweeping new image of the Milky Way's core, previewing the same region NASA's Nancy Grace Roman Space Telescope will survey after its launch this summer. The overlapping coverage means astronomers can combine data from both missions, extracting far more scientific insight than either instrument could deliver on its own. The collaboration sets the stage for a major leap in our understanding of the galaxy's densely packed central region.

New electrocatalyst helps turn polluted water into fertilizer and polymers
Researchers at Tohoku University have developed an electrocatalyst that converts nitrate pollutants and plant-derived materials into fertilizers and industrial polymers in a single electrochemical process. The system tackles two problems at once — cleaning contaminated wastewater while generating commercially valuable chemicals. The approach offers a more sustainable alternative to energy-intensive conventional manufacturing methods.
