Pleiades, in astronomy, a cluster of stars in the constellation Taurus. With a telescope, several hundred stars are visible in the cluster. However, only six stars can be easily seen with the unaided eye. On a very clear night, several more can sometimes be seen. Alcyone is the brightest star in the Pleiades. Bright nebulae (clouds of gas and dust) surround several of the stars in the cluster.
Relying on a collapsed star to power our lives on Earth might seem like a good solution to our energy crisis, but there's just one tiny problem: The process might be lethal.
It's not uncommon for planets to wander alone through the universe like big, sullen teenagers. But how do they end up flying solo, and could they still harbor life?
