The chaotic early phase of the solar system

Before the Earth and other planets formed, the young sun was still surrounded by cosmic gas and dust. Over the millennia, rock fragments of various sizes formed from the dust. Many of these became building blocks for the ...

Researchers investigate 'the Goose' pulsar wind nebula

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 ...

A nebula (from Latin: "cloud"; pl. nebulae or nebulæ, with ligature or nebulas) is an interstellar cloud of dust, hydrogen gas, helium gas and other ionized gases. Originally, nebula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy was referred to as the Andromeda Nebula before galaxies were discovered by Edwin Hubble). Nebulae often form star-forming regions, such as in the Eagle Nebula. This nebula is depicted in one of NASA's most famous images, the "Pillars of Creation". In these regions the formations of gas, dust, and other materials "clump" together to form larger masses, which attract further matter, and eventually will become massive enough to form stars. The remaining materials are then believed to form planets, and other planetary system objects.
