Using NASA's Chandra X-ray observatory and Australia Telescope Compact Array (ATCA), astronomers have investigated a pulsar wind nebula, dubbed "the Goose," powered by a young pulsar known as PSR J1016–5857. Results of ...
Helium-3, a rare isotope of helium gas, is leaking out of Earth's core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a solar nebula, which has ...
