The NASA SPHEREx mission has revealed an extraordinary surge of sublimation activity on the interstellar comet 3I/Atlas ...

What, precisely, should constitute a “clean test” in the event of some fast-moving interstellar object sprouting a sunward-pointing tail and a halo of gas inconsistent with familiar expectations?

NASA's Europa Clipper and the James Webb Space Telescope have revealed the chemical secrets of interstellar comet 3I/ATLAS, even as the hunt for alien radio signals ends in silence.

The interstellar object, 3I/ATLAS, was first discovered in July 2025, and made its closest approach to the sun (perihelion) ...

The international team of astronomers reports that all of the types of ice in the comet appear to be sublimating. This is the phase change where a solid turns into a gas, skipping the liquid phase.

A redesigned low-cost catalyst shows unexpected durability while converting CO₂ into a useful energy carrier. Researchers from Yale and the University of Missouri report that catalysts made with ...

“Basically, the buffer system is the body’s way of keeping the pH stable. So, if we’re blowing out, if we’re having problems ...

Getting to zero carbon emissions won’t save the world. We’ll have to also remove carbon from the air—a massive undertaking unlike anything we’ve ever done. Scientists monitor a mesocosm—an ...

Challenging long-held assumptions, Aarhus University researchers have demonstrated that the protein building blocks essential for life as we know it can form readily in space. This discovery, ...

There’s folk wisdom in just about every culture that teaches about renewable energy — things like “make hay while the sun shines”. But as an industrial culture, we want to make hay 24/7 and not be at ...
