European astronomers have recently studied the chemical composition of the low-mass globular cluster designated NGC 6362. Their detailed analysis of chemical abundances for 17 elements in the cluster provides important insights ...
When a star like our sun gets to be very old, after another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining, it will shrink to a fraction ...
