Understanding Nebulae

A nebula is a giant cloud of dust and gas in space, often appearing as colorful art. Nebulae are far from Earth, and scientists use telescopes to capture their images. They can form from supernovae or be star nurseries. Nebulae consist of dust and gases, mainly hydrogen and helium, which gravity pulls together to form stars. The Helix Nebula, 700 light-years away, is a remnant of a dying star. Future research with telescopes like the James Webb Space Telescope will enhance our understanding of nebulae and star lifecycles.

What is a nebula primarily composed of?

• Light and energy

• Dust and gas

• Water and ice
