Major space and astronomy developments include evidence of Mars's ancient magma systems, the Milky Way's collision history, concerns over space datacenters' environmental impact, and ongoing research into extraterrestrial habitability.

Astronomers at Durham University discovered that the Milky Way was flipped on its side approximately 10 billion years ago following a collision with the Gaia Sausage dwarf galaxy, fundamentally reshaping our galaxy's structure and orientation.

Research suggests Mars once had rivers of magma flowing beneath its crust, expanding the list of rocky planets that could have potentially supported habitable conditions in their ancient past.

Experts warn that space datacenters proposed by SpaceX and Amazon CEO Jeff Bezos could be 'catastrophic' for the planet, with a new US petition demanding environmental review of plans from major tech companies.

Physicist Laura Grego highlights concerns about unregulated satellite proliferation and military applications in space, warning of an emerging 'doomsday system' involving satellites and nuclear weapons with minimal oversight.

The Trump administration proposes changes to EPA public engagement rules that could favor data center expansion reliant on fossil fuels, raising environmental concerns as these facilities increasingly power space and tech operations.

A US-Saudi nuclear deal announced Wednesday could allow Saudi Arabia to enrich nuclear fuel for civilian purposes, prompting warnings from nuclear experts and lawmakers about atomic proliferation risks and potential weapons development.

Recent observations of orcas ramming giant sunfish with explosive force suggest the behavior may serve as entertainment or a teaching mechanism for younger whales rather than purely nutritional feeding.

Studies reveal marine mammals are adapting communication patterns to human activity, with sperm whales modifying their clicking 'vowel' sounds in response to nearby boat traffic in the Caribbean.

A previously documented slowdown in Arctic sea ice decline has reversed, with scientists recording the largest winter ice loss on record, indicating the slowdown was temporary rather than a sustained trend.
