Formed when a red giant star burns through its nuclear fuel and sheds its outer layers, the nebulae (which have nothing to do with planets) expand outward in striking patterns. Some of these exhibit strange properties, according to a new paper, which studied 136 nebulae using the European Southern Observatory’s Very Large Telescope in Chile.Many nebulae close to the galactic bulge – the central sec ...read more

Ever since neutron stars were discovered, researchers have been using their unusual properties to probe our universe. The superdense remnants of stellar explosions, neutron stars pack a mass greater than the Sun’s into a ball about as wide as San Francisco. A single cup of this star matter would weigh about as much as Mount Everest.These odd celestial bodies could alert us to distant disturbances in the fabric of spacetime, teach us about the formation of elements, and unlock the secrets of ho ...read more
