The Vera Rubin Observatory's telescope has begun work in the search for dark matter, the invisible substance thought to make up most of the universe's mass. By surveying the sky in unprecedented detail, it aims to detect subtle gravitational effects that could reveal dark matter's pull. Astronomers hope the mission will transform cosmology.

NASA says a recent attempt to recover the Swift gamma-ray observatory, despite ending in failure, delivered valuable engineering lessons and unexpected scientific returns. The agency is framing the effort as a success for what it learned about servicing aging spacecraft, and Ars Technica reports the story is drawing attention among space enthusiasts discussing the mission's outcome.

NASA has published a summary of lessons learned from the Swift boost mission, an effort to raise the orbit of the Neil Gehrels Swift Observatory. The agency is framing the operation as a test case for future spacecraft servicing and orbit-raising techniques, with findings expected to inform how similar missions are planned and executed.

Edmund Halley House in Oxford, UK is being highlighted as a historic site tied to the astronomer's life. Edmond Halley was appointed Savilian Professor of Geometry in January 1703/4 and is believed to have moved into the house two months later as a sub-tenant under a lease John Wallis had held from New College. An observatory was built there in 1705.

The Conflict and Environment Observatory is pressing for stronger action on the environmental consequences of armed conflict, arguing that full protection of civilians must include safeguarding the environment they depend on. The group says wartime damage to land, water and infrastructure harms civilian health and recovery long after fighting ends, and is calling for this to be recognised in international protection frameworks.

The stratospheric research observatory Sunrise-III has returned new observations revealing intricate magnetic structures on the Sun. Flying high above most of Earth's atmosphere, the observatory captured detailed measurements of solar magnetic fields, findings now reported by science outlets and the Japanese astronomical institute NAOJ. Researchers say the data offers an unusually sharp view of the fine-scale magnetic processes driving solar activity.

A stargazing column reminds readers never to look directly at the sun, noting that only instruments such as the Orbiting Solar Observatory can safely study it up close. The piece highlights how dedicated spacecraft, equipped with protective filters and scientific instruments, observe solar activity that would damage human eyesight, offering a caution and a curiosity for amateur astronomers.

A delegation of ministers and secretaries of state from several countries visited the European Southern Observatory's headquarters in Germany. The visit was led by German Federal Minister of Research, Technology and Space Dorothee Bär, and the group was welcomed by ESO Director General Andreas Kaufer. Such visits typically highlight international cooperation in astronomy and research policy.

A signal originating from deep space has caught the attention of astronomers, according to a report by Root-Nation.com. The origin and nature of the signal have not been detailed, and no space agency or observatory has been confirmed as the source of the finding. Interest in unexplained cosmic signals typically surges when researchers suggest they could merit further study, though most such detections are later attributed to terrestrial interference or known astrophysical phenomena.

The exoplanet HD 224538 b, a gas giant located 258 light-years from Earth, is drawing attention after a profile of its details circulated among space enthusiasts. Discovered in 2016 by multiple observatories, the planet has a mass of roughly 2,076 Earths and an orbital period of about 1,202 days. NASA's Eyes on Exoplanets visualization tool lets users explore the distant world directly.

NASA's Earth Observatory reports that powerful storms continue to move across the Pacific Ocean, documented through satellite imagery of the region. The imagery highlights the scale and persistence of the storm systems churning over Pacific waters. Beyond the headline, no further details are provided about specific locations affected, damage caused, or forecasts for the coming days.

NASA has issued a correction regarding collaborators under the ROSES-25 solicitation, element D.9, which covers the Habitable Worlds Observatory Implementation and Community Activities (HWO-ICA) programme. The notice adjusts who may participate as collaborators on proposals. Researchers and teams preparing bids for the observatory's community activities are expected to review the updated terms before submitting.

Astronomers use powerful lasers to create artificial 'guide stars' in the night sky, helping telescopes correct for the blurring caused by Earth's atmosphere. By shining a laser into the upper atmosphere, observatories can measure atmospheric distortion in real time and sharpen images of distant stars and galaxies. The technique, used at major observatories worldwide, has drawn renewed attention as part of wider coverage of modern telescope technology.

Researchers from Columbia University's Lamont-Doherty Earth Observatory are studying fossil corals in the Cook Islands to reconstruct how global sea levels changed in past warm periods. By dating ancient coral reefs, scientists hope to better predict how quickly ice sheets could melt and seas could rise as the climate warms, informing coastal planning worldwide.

UNESCO has announced an Observatory on Artificial Intelligence in Education for Latin America, a regional initiative to track and analyse how AI technologies are being used in schools and education systems across the continent. The observatory is intended to help policymakers share data, monitor developments in educational AI, and guide responsible adoption of the technology in teaching and learning.
