Neptune’s moon Nereid may be a survivor of an ancient cosmic collision
Astronomers think Neptune’s irregular moon Nereid could be the last intact remnant of a giant collision that also produced Triton, reshaping ideas about the planet’s moon system. The finding adds to evidence that Neptune’s satellites may preserve traces of a violent early history .
NASA builds AI to detect harmful algal blooms from space
NASA says its new AI tool can identify harmful algal blooms even in tricky coastal waters with sediment, vegetation, and runoff. That could improve early warnings for water-quality threats and help local agencies respond faster .
NASA’s Psyche mission captures a striking view of Mars’ Huygens Crater
A new image from NASA’s Psyche spacecraft shows Huygens Crater on Mars while the mission continues its cruise toward the asteroid Psyche. Scientists hope the asteroid will reveal clues about the exposed metallic core of an ancient planetesimal when the spacecraft arrives in 2029 .
Study reports possible dark matter imprint in gravitational waves
Researchers have suggested a tentative dark-matter signature in gravitational-wave data, but they caution that the evidence is far from conclusive. More observations and deeper analysis will be needed before any claim of detection can be made .
NASA’s MAVEN detects first Zwan-Wolf effect deep in Mars’ atmosphere
NASA’s MAVEN orbiter has reportedly observed the first known Zwan-Wolf effect in the Martian atmosphere, adding a new piece to the puzzle of Mars’ upper-atmosphere dynamics. The result could help scientists better understand how energy and particles move through the planet’s tenuous air .
Asteroid 2026 JH2 is set for a close Earth flyby
Astronomers are tracking asteroid 2026 JH2 as it makes a close pass by Earth, prompting public interest in how near it will come. Events like this are routinely monitored to refine orbital predictions and assess any future impact risk .
UN backs landmark climate ruling and pushes stronger global action
The UN General Assembly adopted a resolution endorsing the International Court of Justice’s climate advisory opinion, which says states have legal obligations to address climate change. The resolution urges cooperation, faster climate action, and a transition away from fossil fuels in energy systems .
Australia’s CSIRO faces major cuts to climate-modeling staff
Australia’s national science agency is reportedly preparing to cut about one-third of the team working on the country’s climate model. That model is important for projecting future climate conditions, so the staffing reduction raises concerns about research capacity .
Germany warned it may miss 2030 climate targets
An independent body has warned that Germany is likely to miss its 2030 climate goals and could emit far more CO2 than previously expected. Reuters, as cited in Carbon Brief, says the shortfall may be as high as 100 million tonnes .
India’s power demand hits record levels amid intense heat
India’s peak electricity demand has broken records as a severe heatwave drives up cooling needs and overall power consumption. Reuters and the Economic Times reported that the record was broken more than once this week, highlighting the pressure extreme heat is putting on energy systems .
US EPA moves to delay and roll back PFAS drinking-water limits
The EPA is preparing new rules that would repeal or delay parts of the Biden-era standards for PFAS, the so-called forever chemicals, in drinking water. The plan would keep some limits in place for PFOA and PFOS but extend compliance deadlines and reopen the regulatory process .
Heart attacks may cause brain changes linked to mood and cognition
A University of Ottawa study reported by EurekAlert suggests heart attacks can trigger molecular changes in the brain that may be tied to depression, anxiety, and cognitive effects. Researchers identified methylglyoxal buildup and are exploring a peptide therapy to neutralize it .
