A gas giant the size of Jupiter orbits the pulsar PSR J2322-2650b, heated to 1900°C. Its atmosphere is thick soot of carbon chains, not the usual water vapor. Carbon is a hundred times more abundant than oxygen compared to normal, and ten thousand times more than nitrogen. This doesn't fit the 'blac

Astronomers used pulsars — ultra-precise cosmic lighthouses — to search for elusive dark matter. If it were made of ultralight wave-particles, they would distort the flawless rhythm of these stars. Years of observations showed no disturbances, but for the first time set bounds for two hypothetical f
