Another snapshot of our strange universe: astronomers recently caught a pulsar — a particular kind of dense star — switch off its radio beacon while powerful gamma rays brightened fivefold. “It's almost as if someone flipped a switch, morphing the system from a lower-energy state to a higher-energy one,” stated lead researcher Benjamin Stappers, an […]

But defining a Sun-like star may be just as difficult. A solar twin […]
