The planets are aligning — literally — and the celestial show can be seen in the Las Vegas Valley through the end of February. The event has been dubbed a “planetary parade,” a term referring to ...

I didn’t come to zero-gravity sleeping out of need. It was more of a “why not?” My Bedgear adjustable bed frame, which I’ve owned for years, has a “zero gravity” preset. I’d used it occasionally to ...

There’s a comforting idea in planetary science. That no matter how strange a distant world looks, its beginnings might still feel familiar. For decades, astronomers have argued about how super ...
