Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. This landscape of "mountains" and "valleys" speckled with glittering stars is actual...
Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a dying star—possibly one like the Sun. It is approximately 700 light-yearsaway from Earth. That means even if you could travel at the speed of light, it would still take you 700 years to ...
Astronomers use very powerful telescopes to take pictures of faraway nebulae. Space telescopes such as NASA's Spitzer Space Telescope and Hubble Space Telescopehave captured many images of faraway nebulae.
Learn about nebulae, the giant clouds of dust and gas in space where stars are born or die. Watch a video, see images and find out how nebulae are formed and where they are located.
True color image of the Trifid Nebula, showing complex gas and plasma structure. A nebula (Latin for 'cloud, fog'; pl.: nebulae, nebulæ, or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust.
