Astronomers long expected the Milky Way and Andromeda to collide in about 4.5 billion years — but a 2025 study in Nature Astronomy, using Hubble and Gaia data, estimated only a roughly 50–50 chance of the galaxies merging within the next 10 billion year - Space Daily
The 2025 estimate depended on uncertain motions and neighbouring galaxies. A 2026 follow-up put the merger probability higher, showing why the forecast remains sensitive to the measurements.
Astronomers using Hubble found a new roughly 104,000-mile-wide ten-sided storm forming at Saturn’s south pole, a geometric twin to the famous hexagon that has long circled the north - Space Daily
Saturn's symmetry breaks: a ten-sided storm now mirrors the planet's legendary hexagon, suggesting these geometric puzzles obey deeper physics we're only beginning to understand.
Antarctica gained a record 695 billion tons of ice. Scientists found the surprising reason - Science Daily
East Antarctica gained an astonishing 695 billion tons of ice between 2021 and 2023, temporarily slowing Antarctica’s long-term decline. Researchers found that warming thousands of miles away in the tropical ocean altered atmospheric circulation and funneled …
Triton likely formed in the outer solar system before Neptune captured it, largely destroying the planet’s original moon system. JWST observations published in July 2026 suggest today’s inner moons reassembled from the wreckage — although Nereid may be - Space Daily
Webb spectra suggest Neptune’s inner moons were rebuilt from destroyed icy interiors, while separate evidence casts eccentric Nereid as a possible original survivor.
Arctic Rivers Are Defying What Scientists Thought They Knew About Erosion - ScienceAlert
Scientists have to follow the data, even if it doesn't make sense.
Enceladus is just 504 kilometres across — roughly half the length of Great Britain — yet a 2026 study traced its electromagnetic Alfvén-wave wake at least 504,000 kilometres downstream through Saturn’s magnetosphere, farther than the Moon ever travels fro - spacedaily.com
Cassini data reveal that tiny Enceladus drives a main and reflected Alfvén-wave system through Saturn’s magnetosphere for at least half a million kilometres.
Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning - Phys.org
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study published in the journal JGR Solid Ea…
The only spacecraft ever to visit Uranus arrived during solar-wind conditions seen just 4% of the time, compressing the dayside volume of its magnetosphere by up to 78% — meaning textbook descriptions of Uranus’s magnetic environment may be based on a - Space Daily
A reanalysis suggests Voyager 2 encountered Uranus during rare solar-wind compression, temporarily shrinking the dayside magnetosphere and reshaping its plasma environment.
On this day in space! Sept. 6, 1947: The US Navy launches 1st V-2 rocket at sea in ballistic missile test - Space
The test, while unsucessful, did show that Navy ships could be floating launch pads for a new kind of weapon: the ballistic missile.
SpaceX Falcon 9 rocket launches 27 Starlink satellites, lands on ship at sea (video) - Space
It was the 103rd Falcon 9 launch of the year.
The extinct American 'cheetah' was not a cheetah after all - Phys.org
With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal Current Biology, researchers reveal th…
Fusion in the Sun’s core releases neutrinos and high-energy photons together: a neutrino can reach the surface in about two seconds, while the photons’ energy may take roughly 170,000 years to escape after countless scatterings, absorptions and re-emissio - Space Daily
Solar neutrinos escape from the core in seconds, while radiant energy diffuses through dense plasma for roughly 170,000 years before it can leave as sunlight.
