For the first time, scientists have directly observed twisting Alfvén waves in the Sun’s corona using the Inouye Solar Telescope. The discovery could explain why the Sun’s outer atmosphere is millions of degrees hotter than its surface, offering key insights into solar energy transfer and space weather prediction.

Scientists at NTU Singapore propose carbon-neutral data centers in low Earth orbit powered by solar energy and cooled by the vacuum of space. The concept could help meet rising AI demands while reducing land use and emissions, offering a sustainable alternative for the global computing industry.

SpaceX is developing a simplified Starship mission for NASA’s Artemis III Moon landing, targeting a quicker and safer return of astronauts. As NASA reopens the lander contract amid delays, SpaceX says its refined Starship design could take on more mission roles, advancing lunar exploration toward the first crewed landing this decade.

Scientists have detected two unusual black hole mergers showing signs of “second-generation” origins — meaning each large black hole likely formed from an earlier merger. The gravitational-wave signals also matched Einstein’s predictions on spinning black holes, offering fresh proof of general relativity and new insights into how black holes grow in crowded star systems.

Meta has introduced passkey support for encrypted WhatsApp chat backups, letting users restore encrypted chats using fingerprint, face, or screen lock instead of passwords or 64-digit keys. Passkeys are securely stored in a password manager for safer, simpler access. The feature, rolling out globally soon, enhances end-to-end encryption introduced in 2021. Users can enable it via Settings > Chats > End-to-end encrypted backup on Android or iOS. Notably, encrypted WhatsApp backups aren’t included in regular iCloud or iTunes backups on iPhone.

Scientists using the Daniel K. Inouye Solar Telescope have detected Alfvén waves in the Sun’s corona, potentially solving the long-standing mystery of its extreme heat and helping refine models of solar and stellar energy transfer.
