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.
Jun 13, 2024 · A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.
Jun 17, 2024 · The result is what we call a nebula, and they are among the most spectacular sights in astronomy. In fact many of the most iconic Hubble telescope images, such as the "Pillars of Creation", are...
May 31, 2024 · nebula, any of the various tenuous clouds of gas and dust that occur in interstellar space. The term was formerly applied to any object outside the solar system that had a diffuse appearance rather than a pointlike image, as in the case of a star.
Credits: NASA, ESA, M. Robberto (STScI/ESA), and the Hubble Space Telescope Orion Treasury Project Team. A famous example of an emission nebula is the Orion Nebula, a huge, star-forming nebula in the constellation Orion. The Orion Nebula is home to a star cluster defined by four massive stars known as the Trapezium.
Aug 23, 2021 · The nebula, cataloged as NGC 1999, is a reflection nebula, which shines by reflecting light from a nearby star. Unlike emission nebulae, whose reddish glow comes from excited atoms of gas, reflection nebulae have a bluish cast as their interstellar dust grains preferentially reflect blue starlight.
Feb 7, 2024 · Today, Hubble has observed many of these nebulas and found a wide range of complicated and extraordinary shapes, from tunnels to interlocking rings. The Cat's Eye Nebula, for example, consists of 11 bubbles of gas. The Helix Nebula looks like a giant eye staring at us through space.
