Apr 22, 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. Watch this video to learn all about nebulae!
Apr 29, 2024 · The Horsehead Nebula is a well-known photodissociation region, or PDR. In such a region, ultraviolet (UV) light from young, massive stars creates a mostly neutral, warm area of gas and dust between the fully ionized gas surrounding the massive stars and the clouds in which they are born.
Feb 7, 2024 · How Do Stars Form in Nebulas? Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots.
Sep 6, 2022 · A Cosmic Tarantula, Caught by NASA’s Webb. In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of never-before-seen young stars that were previously shrouded in cosmic dust.
Stars form in large clouds of gas and dust called nebulae that scatter the visible wavelengths of light our eyes can see. The longer wavelengths of infrared light can pass through the cloud relatively undisturbed. Hubble’s near-infrared capabilities and high resolving power make it an important tool in the study of how stars form. Hubble’s
Mar 7, 2024 · nebulium. bright nebula. Veil Nebula. Helix Nebula. 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.
5 days ago · This region lies between the cold gas of the nebula and the charged gas that surrounds the stars. A close-up of the Horsehead Nebula's "mane" captured by the Webb telescope's Near-Infrared Camera ...
