Major discoveries reshape understanding of galactic history and planetary habitability while space policy and environmental concerns dominate the agenda.

The Milky Way was flipped on its side approximately 10 billion years ago following a cataclysmic collision with the Gaia Sausage dwarf galaxy, according to Durham University researchers who analyzed gravitational effects from this direct impact.

Mars once featured rivers of magma bubbling beneath its crust, a finding from Oxford researchers that expands the catalog of rocky planets potentially capable of supporting past life and habitable conditions.

Physicist Laura Grego warns of an unregulated 'doomsday system' in orbit as Elon Musk pursues satellite ownership, competing powers develop space warfare capabilities, and governments struggle to establish meaningful regulatory frameworks for space activities.

The next Space Force chief expressed skepticism toward the concept of space privateers, signaling institutional resistance to privatized military operations in orbit amid broader debates over commercial space militarization.

A previously observed slowdown in Arctic sea ice melt has ended, with scientists recording the largest winter decline on record, indicating the earlier slowdown was temporary rather than a sustained reversal of climate trends.

Sperm whales off Dominica demonstrate linguistic adaptation by changing their clicking 'vowel' sounds when marine traffic approaches, showing behavioral modification in response to human-generated ocean noise pollution.

The US and Saudi Arabia announced a nuclear cooperation deal that could permit Saudi uranium enrichment, drawing opposition from US lawmakers and Israeli officials concerned about potential weapons development.

Scientists warn that a slowdown in Arctic sea ice melt—previously attributed to climate stabilization—has reversed course, with current rates exceeding historical records and reversing two decades of relative stability.

Research demonstrates that monkeys understand geometric shapes using intuitive reasoning nearly identical to humans, challenging long-held assumptions about geometric cognition as uniquely human.
