A star seldom just flies apart – at least not when it’s in the prime of life. But some of them come close. One of the best examples is Regulus, the brightest star of Leo. It’s rotating so fast that it’s barely holding itself together.
Regulus consists of four stars, but only one of them is […] Allan Sandage once said that when he became a graduate student at Caltech, in the late 1940s, he was a “hick who fell off the turnip truck.” He fell at the feet of Edwin Hubble, the most famous astronomer of the time. Hubble was ill, so Sandage gathered data for him at the world’s largest […] As the Moon orbits Earth, its gravitational pull creates the ocean tides. As the “bulge” in the water laps against the continents, it creates drag that slows our planet’s rotation. That increases the length of a day by about 2.4 milliseconds per century. That doesn’t sound like much, but […]StarDate StarDate, the longest-running national radio science feature in the U.S., tells listeners what to look for in the night sky.
