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. For this reason, some nebulae are called
"star nurseries."


Yellow is the color between orange and green on the spectrum of visible
light. It is evoked by light with a dominant wavelength of roughly
570-590 nm. It is a primary color in subtractive color systems, used in
painting or color printing. In the RGB color model, used to create colors on
television and computer screens, yellow is a secondary color made by combining
red and green at equal intensity. Carotenoids give the characteristic yellow
color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg
yolks, buttercups, and bananas. They absorb light energy and protect plants
from photodamage. Sublight has a slightly yellowish hue, due to the surface
temperature of the sun.
