For decades, scientists have tried in vain to accurately predict solar flares - intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA's Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when the Sun is about to unleash a large flare.

McGill University researchers have revealed that changes in cloud cover are helping to slightly counteract global warming. While greenhouse gases continue to drive temperatures upward, a reduction in low-cloud cover over land has contributed to a small decrease in the amount of heat retained near the Earth's surface.

The Federal Aviation Administration has paused SpaceX's launch of its Starship rocket as the U.S. agency oversees an investigation by the private company of the breakup after a test launch Thursday.
The upper stage exploded minutes after launch from South Texas, leading the company to declare the uncrewed vessel a "loss" in the seventh test flight of the heavy-lift spacecraft.

The future of timekeeping is being reshaped by optical atomic clocks, which operate with laser frequencies roughly 100,000 times faster than the microwave frequencies of caesium clocks, the current standard for defining the second in the International System of Units (SI). Some of these optical clocks are already 100 times more accurate than caesium clocks and are poised to redefine the second.
