Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories

Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories This week's science news. It's been an eventful week in science news. Astronauts on the ISS were briefly ordered to shelter in place after the discovery of an air leak in the transfer tunnel, NASA officially declared its MAVEN space probe dead and scientists announced the creation of a "universal vaccine" designed by AI.

Tessera AI model offers accessible way to view Earth

Tessera AI model offers accessible way to view Earth Lisa Lock Scientific Editor Andrew Zinin Lead Editor A foundation model trained on Earth observation data from Copernicus Sentinel-1 and Sentinel-2 has been made widely available to researchers, it was announced at a computer industry conference this week in Denver, U.S. Tessera, an advanced artificial intelligence (AI) model, offers high-accuracy datasets that encode what the satellite "sees" of Earth's surface during the course of a...

Global warming hit 1.37°C in 2025, with Earth accumulating heat at an accelerating rate

Strong and consistent evidence shows that the entire climate system is continuing to heat, driving rapid global warming. Human activities pushed global warming to 1.37°C in 2025, and its level is projected to surpass 1.5°C in about four years. Crucially, the rate at which heat is accumulating in Earth's system suggests high levels of future warming.

Space station dust maps slash climate uncertainty over iron-rich particles

Space station dust maps slash climate uncertainty over iron-rich particles Lisa Lock Scientific Editor Robert Egan Associate Editor New research from a team of scientists led by Cornell is transforming how researchers understand one of the atmosphere's most abundant and least understood constituents: mineral dust. Mineral dust, composed of tiny particles lifted from arid regions including the Sahara, Middle East and East Asia, plays a complex role in Earth's climate system. These particles...

The Role of Source Geometry and Atmospheric Propagation in Global Bolide Infrasound Detectability

Announce Type: cross Abstract: Global infrasound monitoring provides a persistent means of detecting energetic bolide atmospheric entries, complementing optical observations and extending coverage over remote regions. We present a global assessment of the physical factors governing bolide infrasound detectability by correlating 623 bolide events reported by the Center for Near-Earth Object Studies between 2007 and 2025 with waveform data from the International Monitoring System. We identify...

Glass Box at Orbit: A Constitutional AI Verification Framework for Trustworthy Autonomous CubeSat Intelligence

arXiv:2606.02967v1 Announce Type: new Abstract: The space industry is quietly building toward something nobody has fully reckoned with: orbital data centers running thousands of autonomous AI workloads with no human in the loop, 550 km above the Earth. Microsoft, AWS, and a growing list of orbital computing ventures are moving cloud-scale processing off the ground and into orbit. What none of them have answered yet is the governance question -- when autonomous AI systems at orbital data...

Amplified Arctic iceberg traffic reshapes benthic biodiversity

Abstract The Arctic is undergoing rapid warming, resulting in retreating sea ice and glaciers1, yet how cryospheric changes propagate into the deep ocean remains poorly understood2. Here we identify a climate-driven mechanism linking accelerating glacier disintegration to an increase in deep-sea hard-bottom habitats far beyond calving fronts. Seafloor observations in Fram Strait show a localized increase in the density and patchiness of dropstones delivered by debris-laden icebergs.

Global mangrove forests rebound, offering hopeful sign for climate and coastal resilience

Global mangrove forests rebound, offering hopeful sign for climate and coastal resilience Sadie Harley Scientific Editor Robert Egan Associate Editor Mangrove forests, once considered one of the world's most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset by regrowth and expansion. The study, based on four decades of satellite data and published in the journal Science, finds...
