Haumea, a dwarf planet on the edge of our solar system, doesn’t have the same kind of moons as its well-known cousin Pluto according to a new study.

O-type stars are the hottest and brightest stars known. NASA’s Chandra X-ray Observatory has revealed that the magnetic field at the surface of NGC 1624-2 is 20,000 times stronger than at the surface of our Sun. NGC 1624-2 contains a raging storm of extreme stellar winds and dense plasma that gobbles up X-rays before they can escape into space.
